Sony Bravia KDL-46HX800 shuts off on its own and standby…

Customer Question
Sony Bravia KDL-46HX800 shuts...

Sony Bravia KDL-46HX800 shuts off on its own and standby power flashes 7x (overheating), apparently. Already replaced the BAL board, but to no avail.

Technician's Assistant: How old is your Bravia?

About 8 years old

Technician's Assistant: Does the TV menu work? Do you have the same problem on all sources/inputs?

Right now TV will not power on, so menu does not currently come up. Same problem on all

Uh, no. I was hoping for some assistance in diagnosing and fixing the problem myself. For example, can you suggest which board or component is the most likely culprit?

Different tech here...

It won't turn on with the new BAL board installed?

Where did you get that board?

Does it numbers match exactly?

Ask Your Own TV Question
Customer reply replied 2 months ago
BAL board ordered used from eBay because I could not find any new parts out there. Part number is ***** the same. TV will start to turn on then turn off fairly quickly with the standby light flashing 7 times, as before.
TV Technician: Mike G., Technician replied 2 months ago

We have seen this before... since replacing the BAL board didn't change the symptom, this is actually an issue with the LCD panel. I'm very sorry but there is no fix except to replace the entire tv screen which would cost way more than a new 46" tv.

I know this is bad news and very upsetting but please understand I am here to provide an honest answer based on your symptoms and years of experience doing in home tv repairs.

What’s your thought on replacing the G6B power board?
TV Technician: Mike G., Technician replied 2 months ago

Would not help for this issue. 7 blinks is temperature issue with either the BAL or the LCD panel.

Ask Your Own TV Question
Customer reply replied 2 months ago
How about the LCD control board, just above the BAL board? When the problem first manifested itself, The seven flashes began as soon as I turn the TV on, before it had any chance to heat up. Since then it has been an intermittent problem.
TV Technician: Mike G., Technician replied 2 months ago

Slim chance / wouldn't count on it... Guess you can try, if you can get one for cheap and/or return policy allows returns.

Thanks again for the replies. I’m going to try a couple things before buying a new TV.
