Go for a search in google, there are many who provide free schematic and service manuals.

Sounds like a bad capacitor or resistor off the Microprocessor.Need to find which pin of I.C.regulates the color. Need schematic call the company that made the set to get the diagram.(schematic).

My SONY TV Model : KV-XJ29M50. LED will blink/flash twice right after power turn on and cannot display picture.

If the set has a headphone jack, have you tried plugging in a set of headphones?

If the sound works on the headphones, you may have a bad internal speaker.

If you don't get any sound in the headphones, the audio amplifier may have failed as it drives both the headphone jack & speaker.

Please let me know if I can be of further assistance to you.

Good luck!
