Could be a few things..power deflection board, or if your voltages are correct you will need to replace the small signal board..either way it's gonna cost ya...200 to 300 $ for parts alone.

I have a rca hd56w66, my screen shuts off but the audio still stays on. For a few days, it started fading to orange and then to green and then out to black. After about a minute, the picture would come...


Sounds like you lost the power supply to guns, now this doen't mean you have to go looking for it, you will need a repair person to fix it. Word of advise, if you haven't had one of these fixed before it can range in upwards of 600.00 or more to fix now days.

Tv turns on then right back off no pic or sound


It is in shutdown mode. You have an "overvoltage" (regulation) problem or their is a short in one of the many components causing it to be in "over current" mode. Could be as simple as a bad solder connection. This will take someone with some knowledge of the circuits and test equipment to diagnose.

RCA HD56W66 Power Issue


you hear what? is this sound a high voltage static? The fact that you have flashing light means the main fuse is good and your processor is receving power. THe processor is detecting a shutdown situation that causing it to shut down for safety. high voltage situations are the primary causes. but it can be one of about 20 conditions. at the shop we have a computer that reads error codes much like a autombile. the primary things to check for are a shorted horizontal output transisitor. if you hear a high voltage static then it means you tubes are trying to fire but are drawing to much current.

Nothing comes up on tv when i turn ps3 on and controllers wont connect


Read this very carefully. Turn off your ps3 from the back. Then turn it back on wait unit the light is red. Turn on the system through the front keep holding the power on. You will hear a beep one time that just tell you that the ps3 is powering on keep holding the button until you hear the second beep this will rest your video setting. If that dosnt work call me at sony
