Hitachi Convergence adjustment...blurry corners

 

Jeffro
I have an older model hitachi 55" projection TV and im having some convergence problems...the center portions or the TV look great, but torwards that lower left hand corner, its pretty blurry...whats the problem??
 

The red convergence on my 48" (hitachi) TV is not lining up. The picture comes up some-what blury. The red lines appear blury. Please take my note into deep consideration, and tell me what i can do to fix my problem. My home phone is 610-292-0693. Thank you for your time.

Did you manually adjust the convergence??? On my 57", i can manually adjust red/blue via manual convergence in menu..It comes out much better this way then with the "magic focus" button

TAKE OFF THE FRONT PANEL AND FIND THE FOCAS ELECTRONIC FOCAS CONTROLS. USUALY BETWEEN THE LEFT SPEAKER AND THE FIRST CRT GUN. PAUSE A DVD WHEN THE CREDITS GOING. OR USE A MENU IN YOUR SAT RECEIVER TO LOOK AT. USEING THE GRID IN THE TV SOMTIMES IS NOT ACCURATE. YOU WILL SEE 6 SMALL KNOBS (RED,GREEN,BLUE)FOCUS AND(RED,GREEN,BLUE)SCREEN DRIVE .FOLLOW THESE STEPS
1 TURNDOWN RED AND BLUE SCREENDRIVE
2 FOCUS THE GREEN (YOU SHOULD SEE SCANLINES)
3 TURN DOWN THE GREEN SCREENDRIVE
4 TURN UP THE RED SD UNTILL YOU SEE RETRACE LINES THEN BACK IT OFF TILL THEY ARE GONE.
5 FOCUS RED (UNTILL YOU SEE SCANLINES)
6 TURN RED DOWN AND TURN UP BLUE
7 FOCUS BLUE (BLUE WILL NOT BE AS GOOD AS RED+GREEN
NOW YOU ARE IN FOCUS, NOW YOU NEED TO GET SCREENDRIVE BACK
THE BEST WAY IS TO, PAUSE A DVD ON A BLACK SCREEN
SELECT PLAY MOVIE AND HIT PAUSE RIGHT AFTER . TURN ALL THE LIGHTS OFF IN THE ROOM AND USE A SMALL FLASHLIGHT TO ADJUST SCREENDRIVE SO YOU DONT MOVE FOCAS BY MISTAKE.
THE TRICK IS TO END UP WITH A VERY FAINT GRAY SCREEN WITH EACH COLOR UP AS FAR AS YOU CAN WITHOUT SEEING ANY COLOR ON THE TV. WHEN YOU GET THIS TRY PLAYING THE MOVIE. MAKE SURE THE BRIGHTNESS AND CONTRAST IN THE TV ARE AT A NORMAL LEVEL BEFORE YOU START . COLOR,BRIGHTNESS,AND FOCUS IS NOW SET TO YOUR DVD PLAYER.DO A FINAL CONVERGANCE AND YOU ARE DONE!

IF YOU CAN'T GET A COLOR TO FOCUS YOU MAY HAVE TO DO THIS MANUALY. SOME TV'S YOU CAN LOOSEN THE NUT ON THE CRT LENS AND MANUALY FOCUS IT. (LIKE AN OLD CAMERA). IF YOU GET THIS FAR YOU MIGHT AS WELL CLEAN THE LENS WITH A VINEGER BASED GLASS CLEANER (SPRAY THE RAG NOT THE TV) TAKE A LOOK AT THE MIROR, CLEAN IF NEEDED. IF THE MIRROR IS REAL DIRTY THEN THE SCREEN MUST BE BAD TOO.TAKE THE SCREEN OFF AND CLEAN THE BACK SIDE IF NEEDED. LOOK INTO THE LENS AT THE PICTURE TUBE YOU SHOULD SEE A NICE BRIGHT CLEAN PICTURE IF IT LOOKS CLOUDY YOU NEED TO CHANGE THE LIQUID IN THE CRT GUNS.I DON,T THINK YOU WAN'T TO TRY THIS YOURSELF.
TIP(I USE A LITTLE ARMOR ALL WHEN I CLEAN LENES, THIS REPELS DUST LIKE IN YOUR CAR) IF YOU CHANGE YOUR FLUID AND WANT TO KNOW WHERE TO GET NEW FLUID I PUT CLEAR ANTIFREEZE IN MY PIONEER TV 3YEARS AGO AND STILL LOOKS GREAT "NOT KIDING"
HOPE ALL THIS HELPS SOMEONE

That's a good way to screw up you TV. Please have you TV repaired proffesionally.

I would agree with you ,Derek. you can really mess things up if you are not carefull. but if you want to try it, there it is. some people can't afford a service tech to come to there house. adjusting screendrive and focus is about at far as you should go. if you have problems with convergance you'll need a tech to tell you how to get in the service menu to do fine adjustments. sometime you can find it on the net.
