I disconnected it then power the set on. The led is now flashing, no more tick tick tick, secondary voltages are there .I also hearing a bzzzzzgzzgzzg from the chopper transformer. How can I be sure that the flyback (031.54B or HR6572) is faulty? Is it expensive? 2) DVD I have checked the secondary parts and everything seems ok. BTW the 1N5822+ a coil(mark as 100K, the plastic is half melted) + two 220μF for 3V3 and +5V, goes very hot! Tick tick is still there….[/quote]
