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
