TV won't switch on


1. Your Tv is in need of service.
It sounds like the tube that give light to the screen for visual is defective and needs replacement.

No picture


(i) Disconnect all the cables from the TV including the power cable then reconnect them after a few minutes.
(ii) Make sure that the power cord from the TV is directly connected to a functional wall outlet.

If the standby light keeps flashing then service will be required.

BRAVIA KDL-V32A12U PICTURE LOSS


THREE Blinks
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.
FIVE Blinks
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.

Hi, this is a very common failure, you need to replace 2 IC chips on your power supply board, marked on the top of the IC`s is this number: MCZ3001D you can purchase them here if you are very proficient at soldering & un-soldering, and the board has to come out of the tv to do this, you might want to call a tv man for this one, but it will fix your set, happy holidays, BMW Rider
