Hello all,
I got this old LCD TV for free the other day. It does not power on.
When I plug the power cable to the TV it makes a short chirp noise that comes from the area around top/middle left-hand side on the power supply board and the speakers make a popping sound. On the front the LED-bar blinks/pulsates in white color 7 times before the TV shuts down completely.
Upon first inspection I can't see any leaking or bulging caps, I took the power supply board out and re-soldered the points on the transformer but it didn't have any effect.
Any pointers to what to check next? Any help would be greatly appreciated
Read some other threads where the OP replaced capacitor 2165 and 2179 and it powers on as it should. but I don't know if this is the same fault.
I can take more and/or better pictures if needed
