Re: SAMSUNG PS42D4S, won't turn on, no standby
Hello again guys. I left this TV aside as I spent time on some others, gaining some knowledge and now coming back. Changed the IC, nothing found on the rest of the circuit afterwards.
I now plug the TV and I see the relay is not even clicking. Based on the schematic provided, I see fuse F5 before the relay is burnt, MM shows open, while the rest same fuses on the circuit seem fine/beeping. I m thinking if the chip got burnt but nearby diodes seem fine and the fuse is also burnt, if there is definitely something else wrong with this board that caused these symptoms or maybe just a lightning or high voltage from the network.
