Blink 6 times unable power on, but ok after many hours
I’ve a Sony KLV-40S400A that won’t turn on with 6 blinking lights.
The strange thing is if left unpowered on for many hours -12hours, it can power on.
During immediate intervals, 99% chance can’t power on. On with luck after repeatedly power off/on mains then is successful.
Have replaced with another power board from China, which is likely recycled. But the same.
Would anyone able to diagnose what’s likely cause? And why it can turn on after many many hours?
Attached pics of the power board. Appreciate if can point to which component likely cause this issue.
Esta é uma boa pergunta?
