Panasonic tx32lx85p letilt, 3-at villog a készenléti led.
Sziasztok! A készülék bekapcsolás után letilt és a készenléti led 3-at villan. A hiba a tápban van, a 9V-os ág zárlatos. A táp tnp8epl90. A 9v-ot az ic854 hibrid állítja elő és ez zárlatos. Típusa N0Bh2ge00001. Barkács megoldással elindítottam beépítve egy 79s09, 2a es stabot, elindul de hamar túlmelegszik és újra tilt. A gépben csak 24v van amire rá tudom kötni és ez az ág kb 1A-t felvesz, igy persze a stab fűt mint egy kályha. Szerintetek, hogy lehetne ezt elegánsan megoldani. Próbára betettem egy külső 12v adaptert, és arról hajtottam a 9v stab ic-t, és igy stabil lenne, de elhelyezni az adaptert a gépben az elég nem elegáns. Szóval néhány basrkács ötletet szívesen fogadnék.
Panasonic TX-49DX600E TV csak a cstornaszám beütésével vált csatornát
Szevasztok.
A fenti tipusu TV bekapcsolása után csatornaváltás csak az adoott csatornaszám távirányitón történő beütésével lehetséges.
A csatornaléptető gombok használatakor a készülék mindig ráál a 141-es kódolt csatornára és onnan léptetve elmegy a 146-ig
majd cirkulálva ugyanez.A müsortartalom oldalra kapcsolva ott sem müködik a fel-le léptetés. A TV hátoldalán lévő
cstornalépető gombot használva ugyanaz a jelenség. Megköszönném szives tanácsaitokat.
Üdv.
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
