Panasonic TX-L32E5E led tv, hangolás hiba
Üdv. mindenkinek!
A fent nevezett készülék nem hangol le egyetlen csatornát sem. Kapott egy új tunert, de így sem. Tuner  feszültségek rendben vannak, SDA-SCL is elér a tunerig. Egyik pillanatról a másikra lett ilyen baja. Sajnos a tuner csere sem oldotta meg a problémát,  valószínűleg alap probléma (CPU) hibát gyanítok. 1.269 szoftver fut rajta.Találkozott e valaki már ilyennel? Esetleg bontott, jó alaplapot keresek. LA35 a belseje, main: TXN/A10TLUE.
Köszi!
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

Panasonic TX-P42C2E (plazma) képhiba
Udv mesterek. A fent említett TV javításhoz kérnék tanácsot. A készulék mukodik csak a kép kozepén van 1 kb 20cm széles fekete csík fuggoleges irányban. Mivel már volt hasonló hibám rendeltem bele 1 buffer modult (TNPA 5076.1C2). Be is szereltem de a bekapcsolás után (még mielott kijott a kép) sercegést hallotam és gyenge amperszag volt a levegoben. A kép ugyanolyan hibásan jott elo mint a buffercsere elott. Amit még észrevettem, hogy az a coff hutoje ahol a csík van tiszta hideg és a tobbi langyos. Készítettem róla képeket is.
