Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
I am trying to establish if there is a standby power problem.
Yes it has a stand by light and it is red . once the power on is started it checks the rest of the command lines from micro and starts the initialization process once all are satisfied it un mutes the picture
. however it appears your fighting a one problem and possibly compounding the problems now .

Two major problems occur to cause this, and both are on deflection p.c.b. First, after removing the back look for two or three capacitors in the power supply that are bulging or have exploded in power supply and replace. You can see this looking down on chassis and this occurs on the top of the components in question. Second, look for burn marks or arcing around high voltage transformer, or simply a shorted horizontal output transistor. You will need an ohm meter to test the transistor. These solutions have fixed every identical set to yours,(20 or so) If you would rather replace the board try PTS out of bloomington or google your model number for replacement parts. Good luck.

Liz, yes it is a power supply problem, better question is; low voltage or high voltage power supply ? count the blink code, it should repeat the code, once you have the code call your local tv shops and give them the model number of your tv and the blink amount and they`ll tell you price to fix, gl, video-tek
