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

Panasonic TX-40DS630E nem kapcsol be, csak stby van, alaplap: TNPH1116 1A MEGOLDVA
Sziasztok!

Az alábbi probléma megoldását keresném. Van 2db a címben említett Panasonic TX-40DS630E típusú készülékem.
A hiba jelenség az elsőnél az, hogy feszültség alá helyezés után csak stby van, távirányítóra nem reagál.
Viszont a bekapcsoló gomb hosszas nyomása után a stby led zölden villog majd folyamatosan zölden világít, hátteret nem kapcsol, illetve semi élet jel.
USB-n van 5V mert a pendrive világít melyen a firmware van, lehet 1-2 villan is de nem veszi fel a szofver-t.
A második készüléken a stby led 3x pirosan villogott., IROM SOS hibajel volt. Service manual alapján keresgélve volt egy hibás RT7277.
Ez állítja elő az 5V-ot, ezt kicserélve, ugyanabba az állapotba jutott a készülék mint az első, kivétel, hogy az USB-n nincs 5V-t, pendrive nem világít.
Alaplap típusa TNPH1116 1A.

Ha esetleg valakinek lenne erre megoldás azt megköszönném.
