Good afternoon,
I've been looking around to try to find 2 Diodes values on a Panasonic Tv TH-42PV62EH on a power supplu DPK SU2AV-0.
the two bad diodes are D411 and D596, i couldn't find the schematic or diagram nowhere, maybe one of you could help me.
Wish you a good day.
Thanks a lot.
Regards,
This elderly monster arrived with the error “ 4 blinks “ which the manual suggests is a power board fault
There are TWO power boards and a standby power board inside
On removing rear cover there were two swollen 220uf caps on the standby board, sadly replacing them the 4 blinks remained
Swapping the two power boards over[ as they look identical , gives a “ 2 Blink “ error , the limited info in the manual suggesting that the fault is on the lower board [ main 2 ]
Both boards have a PFC voltage of around 380 volts at switch on before the relays click out
I have done cold checks on both boards and there are no obvious differences
As the manual has only a block diagram of the power supply it’s difficult to be sure of values / voltages
Has anybody seen or worked one of these or similar beasts and managed to diagnose the problem
Thanks for looking
Regards Ken
