This can indicate a problem with the high voltage circuits. Since this is a new set, it should still be under warranty. DO NOT open up the unit as that will void the warranty. Return the set or request warranty service. Note the 8 blinks when you request service as that should allow them to bring the correct replacement parts.

Keep us posted.

SOURCE: hey every one im looking for kdl-w40a12u sony bravia schematic diagrams, can anyone help me with that please.thanks a ton in advance

The world is full of free, useful information but schematics for tv sets are not part of the equation. If you want them, you usually have to pay for them. Maybe if you post the specific problem you're having, I can help point you in the right direction as far as fixing it. Schematics don't fix tv's, people do.

Check the fuses on the power board. there is one fuse on primary side and one on secondary side.
Take of back panel and follow plug into the tv.where it ends is the power board.always use caution.the capacitors in there hold high voltage even after unplugged for a couple of days.Discharge capacitors before servicing the board.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.

Sony Bravia KDl-55EX720 Struck by lightning.Red light shines.Nothing else works.


Claim on your insurance. lightning strikes reach voltages higher than a PCB (printed Circuit Board ) can handle. most of the chips inside will probably be bits of burnt glass now.
