Panasonic Plasma TH-85PF12E Error code " 4 Blinks "
 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

Tisztelt Uraim! Segítséget kérnék a fenti típusú készülék tápjában található STR51424 Ic beszerzését illetően. A pont-tal ellátott, vagy M- jelű Ic nem jó csak a natúr! Mivel a készülék a szívemhez nőtt szeretném ,ha jó lenne. Sini, Hornos, Hq- nál sincs az Ic. Kérem aki tud segítsen! Kiépített bontott is lehet!( Csak üzemeljen!) Természetesen nem ingyen! Előre is köszönöm a segítséget! Szép napot mindenkinek!
