Re: Sony KDL-46EX640 won't turn on, 5 blinks on standby light.
I think I may know what's going on and I don't know why I didn't see this before but when hitting power button, when POWER ON goes high momentarily, BL-ERR is going to 3.3V as well, which would explain 5 blink code, not T-Con problem but a panel issue.
The thing is I've tested backlights with back light tester and can force PS on with POWER ON and BL-ON and seems normal.
