BRAVIA KDL-V32A12U PICTURE LOSS
B+ over voltage protection (OVP), unit goes to the standby
mode then displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
AKB circuit (AKB), the timer/standby indicator blinks for about
30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,
try turning up screen slightly.

Sony bravia 32" lcd tv won't power up
Crack open your power supply again and take a look to make sure all caps are intact and not blown or bulging. Next check the main board for any possible caps and resistors, not likely as there is an external ps but possible. If you don't see anything odd then there may be an issue with the controller chip in which case you could replace but it would probably work out to the same price as buyin a new tv

The remote will not turn the tv off or on
If you have dropped some food crumbs in there or dryed up coffee??...it might have stopped pressing on the PCB board..
open the case carefully with screw driver....
you may have to break a glue bond to...
clean the insides carefully and put back together.

I have a Sony Bravia: KDL 32S3000.I loved the TV until recently, when suddenly the picture was a green one. What happened? Is this repairable? All other functions seem to work well"
In past years the Television used Analog components throughout the TV internals. There was RGB Circuitry (Red Green Blue) and all sorts of things that could be adjusted (and go wrong). Thats not the case any more. It's all digital just like your computer and memory. So... lots of high density IC's (chips) and not much to fiddle with or adjust. The HD Display reflects what is stored in the computer video memory. All Large Scale Integrated Circuits.
There are ribbon cables & connectors that get loose or bad connections and then there are the electrolytic capacitors that leak or chemically break down. So unless you are an electronics guy & know something about components there isn't a lot you can do.
Reset the Bravia box. Power Off / On Etc.
Check the connections on the back. Perhaps a loose HDMI connector if the signal is coming in from another source. Unlikely though. Try bumping the TV from different angles or a slap on the back. If there is a bad internal connection then the colour may return in an instant. This would be an immediate clue to the cause.
If all this fails to make a difference... Then it's probably a chip failure from something like internal overheating. Take it to a dealer or technician (cheaper) rather than have them come to you. They have better facilities in the workshop and they will need to open it up. In most cases they will not fix to component level any more. They will just replace the motherboard or whatever with a factory replacement.
Hopefully repair is covered by Warranty or Insurance.
