Hello
First of all I am not professional and not native English speaker. So sorry in advance, if I don't understand something on first time. I have basic electronic knowledge, multimeter, soldering iron and skill. I have a lot of experience in xbox repair, modifying, ....
I have Sharp LC-40LE810E tv.
I think there is faulty power supply. I found a lot of threads here but I couldn't resolve my problem.
When no try to turn on my tv, it won't start. It won't even light up led tubes. I can hear some coil noise from power supply. There is only flashing middle blue triangle (standby probably) led.
It is flashing like. Flash, flash, pause. And again.
I tried measure both led tubes, I am getting same resistance on both of them, so I assume tubes are good. When I try to measure led tubes output I am not getting any voltage. I was checking there aren't any leaking capacitors.
I tried many reset tv combinations, it didn't helped. Optically I can't see any damage or burned parts.
Could you guys guide me what to measure or try to find fault? Or at least help me to figure out what part is wrong, so I can buy some power supply replacement.
I will provide any pictures you will need, just let me know and I will provide everything needed
Thank you
