Panasonic TX-28XD3P (eu2m)
Sziasztok A fenti géphez keresek olyan doksit amin a sorvégfok is megtalálható. Az eddigi 7 letöltött rajzon nem található. A sormeghajtó trafója melegszik, füstöl, az újjal is ezt teszi. köszönöm Üdv
Panasonic TX28LD4P EURO4
Sziasztok! A fent nevezett TV-vel van az a helyzet, hogy készenlét megvan, bekapcsolásra próbál indulni, majd pár másodperc után letilt. Néha a képcső is bevillan. Van valakinek tapasztalata ezzel a TV-vel? Az indítás pár másodpercében rámérve a főbb feszültségek megvannak. (150V, 29V, 15V, 7V, stb.) (Sajnos nem otthoni körülmények között vizsgálom, így behatároltak a lehetőségeim.) Előre is köszönök mindennemű tippet, ötletet!
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 

Regards  Ken
