anyone know anthing about Philips 42" flat screen? I turned mine off last night, today it turned on for a second, then went blank. Philips says I need to take it to a authorized dealer, which is a rip off in our town. The problem is listed on the faqs under "tv went blank, red led light flashes". Philips thinks it may be a power supply issue. Any ideas or experience?

hello friends,

Does anyone have access to the partslist of the X-SUSTAIN board of a Plasma Panel Daewoo Dsp-4210GM with SP-110 chassis?

I found a shortcircuited Mosfet SSH25N40A (QU4) , also in the Gate of this Fet i found a burnt SMD Resistor RCU20.

Does anybody know the value of this resistor, please? It is totally unreadable.

Thanks for any input!
Grtz,
Techx

Greetings, I have a NEC 4205W that is in great shape, the picture just went off. It powers on and the fans works fine, it took it to a plasma repair and I think he said it needs a digital board or power board, something like that. Can anyone out there help? I would also consider selling it for parts too.

Hello all,
I'm selling an NEC PX-42VM2A (NEC 42MP2) Plasma on ebay if you want some parts. I'm not sure what's wrong with it, it just goes to standby when energized. None of the glass is cracked in any way. If you win the auction and just want the circuit cards, I can remove and send whatever you want. Here is the listing.

I have this Philips 23" plasma hd/tv monitor and as you can tell it has been kicked. The first pic is the screen when its on. It works fine, just the screen is trashed. Is there any one who knows if this screen can be replaced? I'm thinking it can't. Any ideas what the cost will be to fix it or how much I can get for it as-is? If you know a place on the WEB I can sell stuff like this it would sure help me out. Thanks

Hey,

I bought a Phillips High Def plasma tv about a month or so ago. It has a small crack at the bottom of the scree, which can't be seen in the picture. What would be the cheapest process to fix this? And can it be fixed. The model no. is 42FD9954/69C. I am worried it will cost me close to what I paid for it to fix this. It cost me $5000.

Any help is appreciated

cheers

Shannen,

There is absolutely nothing that can be done with a shattered or cracked plasma or LCD panel. There is no miracle glue, no special machines that "buff" out cracks or any other nonesense like that.

Both LCD technology and Plasma technologies are based on disposable panels.

Sure, there are scams and illegal things you can do to get you a new tv set, but if the question is about REPAIRING a panel, that's an easy answer: Not Possible.

We have over 500 broken plasma tvs in stock. If someone wants to tried out that miracle potion, they can buy a broken one from us! hehe ;)

Hi,

Samantha, I think what you are suggesting would loosely be regarded as fraud/theft.

Oh, have you heard of serial numbers? the long number they put on things to give it a unique ID which generally tends to be on the product box aswell? Manufacturers have met your kind before.

Ali, in your stock of 500 broken plasma tv's would you have a Fujitsu PDS4211 or any Fujitsu - I will need some parts for my sick plasma.

I need a PDP for a Fujitsu PDS4214w-s. My Plasma 42" Fujitsu did the loud pop thing and the screen went blank and I took it to an authorized dealer and they said I needed a new PDP # 8110753007. The machine was mounted on the wall and was completely intact when we were watching it - then bingo, it went out. Does anyone want to sell me that part out of one of their broken machines? Please email back - thanks.

If you were in San Diego, California, we would be able to fix this for you with a 2-3 day turn around (we have all the parts in stock). My guess is your video module.

I have a broken 50" Panasonic plasma tv model #TH-50PX25. It's about 2 years old. I moved from San Diego to Atlanta and the damn movers broke it even though they thought it would be fine. Well I heard about the crazy costs of around $1800 but due to time constraints I had to buy a new one. Basically I'm trying to offload the broken plasma tv. The plasma is cracked, not the glass protecting it. When you turn it on a high pitched buzzing and no picture is what you get.

Let me know if you're interested. anthony.leadbetter@gmail.comUpload

I have all the internal cards (carefully removed) including the power supply for an NEC 42MP2 Plasmasync. The glass was broken during shipping. Plasma was about 2 years old and working when it got broke. I'm asking $400US or best offer, and you pay shipping (shipping will be a lot less than sending a Plasma television). If you would like these sent to you, contact me at esisneroz@yahoo.com

I got an NEC 4203MP3 Plasma screen. it is in a metal box and that is in a cardboard box. the Guy I bought it from told me it needs two boards.
and I/o Board and a Power supply.

What is the cost of these two boards?
also this may be out of my league, so I might like to sell the plasma screen.

any offers for the screen, or anyone selling the two boards it needs?

I have a Philips FD429954 which wouldn't power up. I took it to the local "authorized dealer" and turns out the power (port) supply went dead. Cost of the part 1300 plus 300 to repair. I think I found the exact tv with no picture but powers up. Is it very hard to take the part out of these TVs? Hopefully I can save a little bit of cash. Thanks for your help.

There is a guy using a name, Eric Vergas, and live in 13343 nw 3rd LN miami,FL 33182. He will state that he has your replacement screen with a cheap price. Actually he doesn't have anything. This is just a scam.

I wanted anyone who may have experienced a "pop" and loss of image on a Sony Plasma PFM42B1, to know that it is most likely a manufacturer defect and they will fix it for free (if you're in the states). If you own one of these early model Sonys like I do, and it pops and stops working, contact Sony and arrange for them to fix it. They sent me a crate, and sent movers to help put it in the crate and take it to the service center where they fixed it and returned it to me within two weeks!!! For NO cost!! Don't give up on it!!

Original Message posted below:

Hi All, yes I'm one of the suckers who went out and spent an ungodly sum on my Sony 42" Plasma (PFM42B1) about 4 years ago and just last night heard that famous loud POP and now it's dead. So, from what I'm reading I'm guessing I'm screwed? Any suggestions on how to go about finding someone to fix it? Or someone to buy it for parts? THANKS!

I have a Prima 42" Plasma (PS-42T8) that someone broke while trying to steal it from my office, and as it's trashed I'd like to turn it into a coffee table! The front glass is intact, but all the guts are broken.

What do I need to know about the electrical components inside, so that I don't shock myself during disassembly?

thanks for any help you can give,

Anyone trying to rebuild a daewoo is out of his mind....daewoos are disposable tvs no matter what type of tv it is.
toss the thing and just buy a new one its not worth the trouble.
For those of you that have no idea whats wrong with your tv...heres a little tip.

This may seem wrong, but at the time I did it i really couldnt afford to do anything else.

I had a tv that did nothing when turned on.
Not knowing a thing about TVs other than signal stuff because I was a cable tv installer for years, I wanted to find out exactly what was wrong with it.
I called the local in home repairman that gives free estimates.
He came to the house and told me it was the flyback transformer.
Just to make sure, I called another free in home estimate guy out and he said it was the same thing.
They both quoted me a few hundred dollars to fix it.
I told them both I could not afford the repairs at this time.
Then I called the manufacturer as soon as the 2nd guy left the house and had them ship me the part.
I paid 80 bux and the part was at my door the next morning at 11 am.
That night i had worked to remove the old one, and was ready for the new one.
After I installed it, the TV worked like a champ until the day several years later when I gave it away....as far as I know it could still be working.

i understand that it is not economical to attempt to repair my cracked screen 42" panasonic plasma. what i am wondering is if because the PDP is cracked (the glass is not cracked), will the display ever turn on again, is there something i can do to get it to turn on? I would really like to keep this tv and use it as an aux. tv if i can get the display to function, is that possible?

If you heard a loud pop and your plasma then goes dead even though your plasma screen is OK then it's likely a bad Power board. Many in this forum believe it's a capacitor(s) that's gone bad that's caused the popping sound but in fact it's usually one or more defective high voltage MOSFET power transistors that caused the popping sound.

These are notorious for self-destructing with a loud report. Capacitors usually just fizzle as if something were cooking. The HV MOSFET's supply the very high voltage the plasma screen requires and they are extremely susceptible to stray static electric charges. Particularly if the POWER board is not well shielded or grounded.

Sometimes, in environments where static electrical charges are picked up by users who then touch a plasma display or associated components connected to the TV, may trigger the internal HV power MOSFETs and cause them to fail. When they fail, a loud pop and an accompanying acrid smell is often experienced. It's a fairly common problem with Plasma TV's although not readily admitted to by the manufacturers.

For those with electronic experience and know how, many of the PS modules can be repaired by replacing the HV MOSFETs and all the driver transistors and nearby components. There are usually three to four of these HV Power MOSFETs on the same heatsink assembly. When one goes it's usually standard practice tto replace all three or four because if one goes there is a cascading effect that ruins the others nearby. Best practice is to replace all of them. Search the web for replacement HV Power MOSFET's suppliers. Get the part number off one that hasn't self destructed. I bought ten of these for less that $50 on the web.

I've successfully repaired several power boards for different manufacturer plasma displays and brought them back to life. All without service manuals or schematics!

For those that are electronically literate this may help you save the cost of replacing your Power board, or at the vey least tell your service personnel to check out the HV power MOSFETs.

It's a shame that in today's world most technicians are clueless about basic electronic theory and are only capable of replacing entire board modules or subassemblies rather than identifying defective individual components.

Hope this helps someone.

Found this thread on a google search. I recently accquired a NEC PX-42VP1A. It powers on and after about 3 seconds it shuts back off. The display comes up but only for a second. According to the manual this indicates a non-working fan or short circuit. The fans work so I'm left thinking its a short circuit. I am looking for a RPS-9281 Rubycon board to replace it. Other numbers on it are: D9281M-01 KS N80 ; 79646681

If anyone has one, can you let me know the cost if its used but working? Are there any other tips anyone can give me as to why this doesn't work aside from the board? If it helps there is a red light that comes on (in the back of the tv with the outer shell off I can see it on the Analog power board) Is this normal?

Does anyone know any sites to buy the needed PSU board?

Just as an update, I spoke with a repair shop and the board part number has been changed for my particular plasma TV to 79646683 and I found one for sale on some website for 800 bux. If anyone has the matching part number and can save me some dough, please let me know.

Advice Needed Please!!

I have a Philips 42FD9932 that is about 3 years old. It did the loud pop, red blinking light thing a few months ago, but after powering down a few hours, it came back to work another 3 months with no trouble. Popped again last week, and is no longer working. Heard about the Power Supply board issue and was ready to buy one, but a local tech offered to open it up with me and check the boards for $50.00. Appears the P/S board is ok, but 2 of the "chips" on what he calls the "scan board" have what appear to be small burn holes on them. This board has a ribbon cable that seems to be permanently attached to the screen, and I was told that the board in these older models is non replaceable, and the chips are not removeable either, and that essentially the TV is now a boat anchor.

Can anyone concur?

Thanks!

I don't concur.
Those holes may be normal as I don't see any discoloration around them.

If you heard a loud pop, it's highly likely that a MOSFET Power transistor blew on the PS board. IC's rarely go "pop" when they malfunction. Have the tech re-examine the PS board and visually check all the transistor with heat sinks to determine if any are discolored or ruptured. Use a magnifying glass and a flashlight and visually check every component that has a heat sink for physical damage and discoloration.
If you find one get a tech that knows how to replace it and has a schematic diagram or simply get a new PS board. Also check any fuses on the PS board.

I have a broken NEC PX-50XM2A monitor.

The proper image appears but at what looks like low intensity. There were a number of strip artifacts as it failed and some popping coming from the right side of the screen as viewed. I opened it up and was able to verify voltages but since I have no manual was unable to verify waveforms. I believe that the horizontal controller board as failed. It is at the right side of the screen and seems to control the entire image.

Does anyone have a service manual? Have parts available? Advice?

I have a Zenith 60" P60W26. I have lines that have recently appeared on the upper half of the screen. Some lines are red, green, blue, etc., but they remain on the upper half.

As the screen heats up, the lines become less noticeable. The TV has less than 8,000 hours of viewing time on it. Any advice? Is it serviceable? Any help is appreciated.

I have an Akai 42" PDP4225 plasma which has green pixels around dark areas and in many other places as well. When I power it on it is bad. Seems to go away for awhile after 10 minutes and comes back later. Sort of like rings of green pixels that denote a particular color gradient.

Is there a hidden menu for professionals to go in and adjust color temp etc?

What could this be?

Bob- Many plasmas do have a service menu that allows access to adjust the color decoders. Depending on the plasma, the actual number of decoders may vary. Panasonics have three, current pioneers have six. IN any case, may be you should call an iSF certified calibrator and see if they are familiar with Akai plasma ( who sources the glass and electronics--Akai doesnt make plasma glas as an FYI--they are getting it from somewhere else) or call Akai and see if they know the answer to the color decoder question. Also, keep in mind that white light should be adjusted first. If its off, then the colors cant ever really be collectively accurate.

Thanks.

I had an older Pioneer that had a problem with green pixels that started appearing along the top after the plasma had been on for an hour or more.

I found out how to get to the service menu, not available to normal users, and was able to use the service menu to lower the power level going to the screen and turn no the fans full time instead of intermittedly. That solved the problem.

Can't help but thinking this is similar. But it is not associated with heat buildup like I think the Pioneer was. This Akai has the problem all over the screen when you first turn it on. Later it goes away but returns. It is almost like it was a reverse of the heat problem, that is it happens when the set is cool not hot.

I am hoping it is a setting and not a board problem.

Hi I am new to this forum, I have been looking for some help with this technology. I have recently acquired a 42" Panasonic plasma TV monitor. All I have is the TV portion of the whole assembly. ( Someone threw it away) I plugged it in and the screen does light up, but the unit powers down after a minute or so. I heard something rattling around, and last night I got ambitious, opened it up and found a screw bouncing around inside. I found a missing screw on a ground strap on one of the boards, gave it a shot and put it back together. To my surprise I was able to get it powered up and I got a picture. Problem is the picture kept cutting in and out. I am wondering if the screen is interchangeable with other Panasonic units. It was manufactured in 05. I have found several damaged in shipping "new" units on Ebay.( that way I get the stand, remote etc.) I have a good screen, just a bad board somewhere. It would be easiest to swap the screen and have all new internals. They look very similar in the pictures. How much damage do the boards take when a screen is damaged? Is there an interchangeability list somewhere? Or do I need to look for the exact same model? I would like to fix this on the cheap, maybe make one good unit out of two....Any suggestions? Thanks K

Hello All,

I have a Samsung 50" DNIE HPN-5039. I have had it for about 3 years with no problems. We use the plasma on a average of about 4 hours a day. Everything was fine and one night the picture just went in the middle of a program. There is sound, but no picture. The plasma is mounted on a wall profesionally and I had upgraded cables installed to the speakers and DVD., it's in tac and looks brand new. Any ideas what this could be. I know nothing about plasma and could use some help, Thanks..

I have a Dell 36' plasma TV that is on my wall, when I was moving it it bumped up against the end of TV stand and the top right of the screen was damaged. It's not cracked or anything and looks perfectly fine when it's turned off. When I turn it on there is a circular crack and many cracks that break off from it. Also, I can't turn the channel or anything. From what I've seen about broken Plasma TVs, it's usually actual "cracks".

Does anyone know the problem and if it can be fixed?

I have a non-working 42" NEC PlasmaSync 42VP4 for parts or repair. Was told by NEC tech support that it probably needed a new "PDP" module. I'm including the wall mount. Listed on eBay starting bid of $99. (Item #130133683413). Hopefully someone on this board can fix it and put it to good use. Thanks!

Hey Kewlguy28. I had a NEC PX-42VP1A and it had about the same issue. I was told by several repair shops that because of its age, it probably isn't worth fixing. I ended up posting it on craigslist and sold it for $300 in a week. Maybe you can give that a try to and see if you can get more money out of it. Either that or sell the parts individually on ebay (worth more that way). TV repair shops are generally looking for that kinda stuff.

I really need someone to reply to my post, my Dad is going to kill me if I don't find a way to fix it. It was laying on a table thing face down for a second then I heard a small crunch sound and it was like that. It's not physically cracked and you couldn't tell it's broken if it was turned off.

Kevin,
Check the sides of the tv (or your user's manual). I had the same issue with the power button on the tv not working because I had them disabled. It was a little button I could press on the side of the tv. As for no display, only thing i can think of is to check your source and make sure its on. Try a different source to verify that works, and if it does, you might have a bad board.

Hi, I bought a new 42'' panasonic plasma and it came with a long crack across the display panel, and another piece is broken.
My wife didnt check the content when she signed the delivery (I was on a business trip) which would have saved us the whole frustration cause she could refused the delivery.
Im going to contact the company tomorrow - has anyone faced this situation?

On their site they mention that they have no liability if customer accepted and signed the delivery?

The plasma is still in the box as we got it.

any ideas? please advise!!!

Hi, I am a HP, Vizio, Dell, Pioneer tech along with other brands. I am looking for junk plasma's and LCD's in the Texas area to purchase for used parts. Don't bother asking a $1,000 out of your TV you will never get that much when ebay sells 50-60" broken plasma's for about 100-200 each. You can contact me at cowboypoet@gvtc.com with the specs and your asking price. I will then contact you and let you know if I will pick up your TV. Also if you have a board problem, you can also contact me about repairs, I do board work to repair these and I am resonably priced. I am in the San Antoio area to let you know where you can ship or drop off your TV for repairs.

Hi all... Hoping I can get a little help and save alot of $$. I have a Panasonic TH-42PD50U with a thin white line running up and down the left side of the screen. I have identified (I think) the cause, and need help with a fix. Inside the set, there is a series of ribbon type cables that "plug" into the bottom of the screen. The cable itself appears fine, so I'm thinking (hoping) there is an impediment on the inside contact. How can I clean these contacts?

First of all, you can go to radio shack and get a can of contact cleaner that will do that job you are wondering about. Secondly your problem sounds more like a board problem and not with the ribbons at all. It would probably help you to call the manufactur's tech support and just ask them general questions about the possiable problem. I am betting they will tell you that either the X or the Y board will need to be replaced.

Thanks Dale. Hope you got my email yesterday. I'm going to try the cleaner. Another tech had told me that this could be a problem with an IC controller (or something like that). I noticed when I pull this ribbon cable out completely, I have a wide swath of white screen. When it's in, there is only a white stripe. Hoping it's just oxidized and can be cleaned...

It has good audio but bad video after a power outage. Vertical colored stripes with varying color per in the stripe per picture. Channel display makes white strips. Some guys say YSUS board and 2 driver boards bad, another guy says CTL board and 2 associated boards. Need to undertand what board does what and which is bad. Too expensive to experiment with buying wrong boards.

I took mine to Ali at Discount-Merchant.com (see earlier post in this thread). I blasted the internet for advice on fixing my plasma and got totally differing suggestions. So taking it to him was the only sure bet. Luckily it seems two Y driver boards were bad - the cheapest boards and he had them in stock. There are also some voltage adjustments suggested after boards are swapped and you likely will not have the equipment to do them.

Oh, also, given the problem you cite, it sounds like what is called a chip on flex. The chip is on the flex circuit that goes to the plasma tube directly. I am not sure how they fix that. Do a Google search for PDP42V6.pdf and download it - look at page 13. (too big to attach here)

I have a 42" Plasma Monitor PFM-42B1 that goes blank usually after several minutes and occasionally goes all day without fail. The picture when working is great.
When it goes blank, I don't hear any perceptible sounds. The standby led light red starts to blink 6 times and then repeats. The 5 or so internal fans also stop and no power seems to go to the display or circuit boards.
I have taken the back panel off and inspected all components, boards and wiring and found no visble damage. I've cleaned the back panel and all the circuit boards with a PC Spray can made for cleaning circuit boards.
Can someone help me find the problem?
If you know of someone who can fix the problem or that has components that will fix it, please contact me at nkrjhr@gdinet.com. Wisconsin

Hello all I have a Panasonic th-42px60u that needs fixed. The TV has a line about a inch wide going down the left side about 6 inchs in on the TV. I took it to the local shop and he told me it would cost over a thousand for the repair. I have already purchased all the boards from ebay to fix this problem because I thought that it was a issue with a board. Any help would be great, I think the service person told use that it would cost alot because the TV looks trashed after getting it back. David

David, the reason it will cost so much is because the plasma panel itself will need to be replaced. I had the same problem, bought new boards, and then found out that the cables that were bad and causing the white line were integrated into the screen itself, and not user replaceable or repairable.. Sorry for the bad news...

Problem probably with chip on flex (COF). If you find a broken screen unit cheap you may be able to take the chip off it and put it on yours. But it is surface mount work and very tricky to do. Might also be a driver board but you would want to find someone that has them to try a swap. What area are you located?

I'm really good with this and working on boards I have exp with Computers and such and after looking at the TV I thought I could fix it. At this point I'm going to tear into it and try to see if I can because if not its just going in the trash so later when I'm at home I'll take a picture and post it. Thanks for all the info.

I have a Panasonic TH-37PWD4 that is not functioning properly. A few days ago the top half of the screen started blanking out intermittently. I called Panasonic and they told me to do a hard reset by unplugging the unit. It started fine after this, but then went back to black on the top. I again turned it off, and when I turned it back on the top of the screen was multi-colored. The pixels weren't forming the image. The closest repair shop wants $100.00 just to look at it, and that's if I bring it to them. I build my own computers, etc. so if it's just a board I can order and replace that myself. Can anyone help?

For all of you with Broken plasmas or LCDs I feel for you. My daughter broke my new 47" lcd right before christmas.. basically an 1800 dollar loss. My suggestion.. pick up a screen protector from http://www.tv-armor.com It stops people from cracking the screen accidently. Now I dont worry about her playing near the TV.

Hi Paul,
regarding your 50" Pioneer PDP screen issue,.... no, there's nothing you can do except have the screen replaced, which unless you can find a good used one from a reputable source, is too expensive, and not worth it.

All, a lot of the problems for plasmas are power supply problems. the displays are expensive so they cheap out on the power supplies. the best way to see if it is a power supply issue is to remove the back, power turn it on, and look at any LED power indicators on the boards. If you see the power led flickering on a power supply board or other board, its a power supply issue. In this case, its usually bad capacitors and sometimes a chip. Take it someplace that actually fixes TV's and you can GitRdone for about $300 or less.

Note: when the power supply is going out, you may notice that it takes an increasingly long time before you get a viewable picture. during warmup you might see stripes, colored boxes, or other nonsense.
