I have a ProScan PS52690 52" projection TV (CTC188 series) that won't power up. From what I have read here and other places, the most common cause of this is the HV splitter. Actually, when the unit was 3 years old, the HV splitter went out and had to be replaced but it was under warranty at the time. I have found that the part I need is 205064 and runs around $40-$70. It is not worth it to me to have a repairman charge me $300+ to fix it. I want to do it myself but would like a little more information.

A post in another thread said that you could test to see if the HV splitter is really the problem by disconnecting the HV anode (big red wire) from the flyback (not the splitter since that will arc), plug the TV in, power it up, and if the power stays on and you hear sound, replace the HV splitter to fix the problem.

I have created a web page with pictures of the unit at

I will post everything I do and the final result to my web site when I finish this project. Thanks for any help.
