SONY 46" 7 red flashes.. KDL-46EX703

Hi All,

I have a SONY KDL-46EX703 that soon after switch on it switches off and you get 7 red flashes, I have seen another post titled "SONY 46" LED TV 7 Blinks" this refers the the HLR or BAL PCB. I noticed the attached service manual but could not see my model number on it but similar ones.

I have checked internal fuses and also for any obvious bulging caps, but still the same. Am I right that it is not the correct service manual?

Hi Guys,

Anyone have a suggestion or service manual to help find the issue as it is a great set and would be a big shame to dump it.

7 blink code main board or power board fault? we need more info, you say it switches on how? screen lights up? shows image ? for how long ? you say you have checked fuses most Sony mains have loads of SMD fuses on both sides of the boards, they are normally well marked around the edge of the board with arrows pointing to the fuses, have had one with open LEDs on edge light strip. the clue to this is a back light flash then shut down.Do not recall a blink code with that fault, but I do not trust any so called blink code.more info and photos would help
