Hi everybody, my first post here.
I've found on this site many information and the service manual about the TV in subject, but I stumbled upon a strange issue.
I repaired the earphone socket (pic attached) that had been stripped away and now the TV doesn't power on, it only gives a short beep when you touch the power on button and nothing happens using the remote. I checked the usual things (audio paths, cracked solderings, damaged tracks, power supply, power rails), but I cannot found what's wrong.
Any idea/clue on what to (double) check this time?
Üdv!
A készülék pár percenként kikapcsol újraindul.
Eddig arra jutottam, hogy nem táp hiba. Ha folyamatosan kényszer indításba teszem a tápot akkor a feszek megmaradnak. A készenléti fesz is stabil. Amikor kikapcsol, akkor a power on láb lemegy 0 ra majd pár sec és újra vissza3,3vra. Az inverter kapcsoló láb is hintázik ugyan igy. A vez feszek a sub micombol jönnek, de nem tudok rájönni, hogy mi kapcsolgathatja ki be. A tápja stabilnak tünik a procinak. Tasztot levettem de nem segített.
Sziasztok !
A kérdésem a következő lenne.Van ez a címben említett tv-m. A hiba jelensége, hogy bekapcsolás után szalad a kép, és nagyon szemcsés lesz.
Mi lehet a problémája?
Ilyet produkál a hibánál.
