Hi.
I have LCD TV Philips with power inverter board problem.
TV Philips model: 20PF4121/58, chasiss LC4.1E AB
power inverter board model: DELTA DAC-12M019 AOF, REV.05
After electrical shock by storm is dead.
No any visible damage or short circuit found.
I replace some sensitive parts on board,
U101=EA1523A, Q107=11N80C3, optocoupler U100=PC817.
No power up.
Can not found schematic for this power inverter board to check carefully small smd resistors which many are not standard values and is very hard to check if resistance is correct.
Any help, experience with this power inverter board?
Thank you.
