Re: Sony Bravia KDL-46EX640 no power
as a summary for this specific problem of No power No standby problem:
1.) Bought power supply board from Shop Jimmy, problem is still the same.
2.) Bought Mainboard from another vendor though not brand new, the result is Power is
now OK as well as the standby voltage is now present. The "only" problem is the
that there are some "green lines" appearing on the screen. Please refer photos
posted. This Mainboard is actually from the 55" model of this TV series. Second, I
cannot change some parameters even following the manual on how to change some
parameters.
3.) Bought and LVDS cable from another vendor (another pullout from the same tv model)
Result is still the same.
4.) Bought T-Con board from another vendor (still another pullout), same result.
5.) Not yet convinced, bought another T-Con Board from Shop Jimmy, same result.Comment

Did you manage to clear that Main Power error?
Some electronics, return to normal operation after clearing a previous error code.Comment

Re: Sony Bravia KDL-46EX640 no power
Ask shopjimmy how to update the firmware on this board.
You should probably open up the firmware somehow and edit the version of the firmware.Comment

Re: Sony Bravia KDL-46EX640 no power
This is the Only Sony KDL post I can find.Sorry if I posted in the wrong place.
My Sony KDL-37EX403 LCD tv,won"t switch on anymore.When pluged in the power socket the Green light comes on for 2 seconds and then goes off and the Standby light comes on then Blinks for 7 times,if I press the power on on remote or side of tv the standby light blinks 3 times then pauses and repeats 3 blinks.
I dont know anything about tv"s but would be willing to repair the board if there is a KIT for my model.
Any Help would be great.Comment

7 red flashes- main board over heating, can be short on power board or main logic board, maybe blow out any dust if you haven't already.Originally posted by Freko View PostComment

Re: Sony Bravia KDL-46EX640 no power
3 red flashes is bad main logic or power board, check for standby volts if ok replace main logic board.Originally posted by Freko View PostComment
