Re: ProScan wont turn on

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
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.

Splitting a RCA Proscan 60 in 2

If there are plastic plugs on the sides of the tv (4) then you can take them out and expose a screw that if taken out will allow for this, otherwise you will have to get creative. good luck

Green Screen

put a fan behind it, if it works then its heat related if not then you probably need a new main board.

On and off switch won't respond manually or with remote.

Sounds like you have high voltage, I would have to guess the vertical IC has failed. its in the high voltage board and should be done by a qualified tech.
