Question about RCA D52W19 52" Rear Projection Television
When I turn on power button green lght ciomes on then powers off
My RCA D52W25 brought on Jun 2005 had the same problem 7 months ago: I turn it on and the green light blinked couples of times and then go off... not sound or picture at all. It also had a high pitching sound on the back because the flyback was arcing. I bought a new flyback and replace the old one, but again was arcing.
I talk to a technician and he told me to replace the Vertical IC (Vertical Deflection Booster P/N TDA8177F), That fix the problem with the pic and Sound, but the flyback was arcing and makin a popping sound. So, I took RTV silicone and sealed deep around the red power supply wire and that fixed the problem. Now after 7 motnhs, again I have the same problem with the pic and sound ( no problem with flyback). I will have to replace the IC TDA8177F again). Note: Use the IC with the F letter a the end, I used one without it and didn't work.... they are different.

Replace 2200uf 16v capacitor,and two 220uf 35volts they are located in front of chassis on power board Green and Gold colors noise sound or squealing sound is caused by coil LL037 also on same board.

My d52w19 chassis itc222 as posted most of the time wont turn on and the green light flashes three times every time it makes a small noise. sometimes it does turn on and you hear a little pop and the tv fires up. latley there is a really high pitch noise that will slightly change pitch if you move the tv or put slight pressure on the top or botttom rear part of the chassis. thanks for the help as I have seen that this has been posted before without mention of the high pitch noise.
