Samsung sct11d nem kapcsol av-rol tv re es forditva
Sziasztok. Az a gondom hogy ha jel van a tuneren és a scartban is egymást zavarják, mind a kettő akar egyszerre menni. Külön külön mindkettő tökéletes. Miért nem kapcsol szét az av a tv módtól?
Samsung CK5020 SCT11B hanghiba
Sziasztok, van itt egy ilyen készülék javításra. Az a gondom vele hogy AV-ről nézve van egy alapzaj (surrogás jellegű). A hangerőszabályzástól független, kivéve ha nullára veszem a hangerőt, ebben az esetben eltűnik. de ha már 1-re állítom, akkor kezdődik. Ez így van, akár DVD-t, akár beltérit dugok rá. A tápegysége rossz volt, (145 Volton járt) SMR KITT beépítése után ez rendbejött. Rajzom van, ötletem nincs a hanghibára. Scartcsati kissé kontakthibásnak tűnt, azt is átforrasztottam. Esetleg ötlete valakinek?
Samsung S15A. nem kapcsol be.
Üdv! Van ez a samsung tv S15A- sassy. az van vele,hogy bekapcs,ég a zöld led,és nem indul be a tv. Kicseréltem benne a TV procit, Tda-t,és utána egyből be tudtam kapcsolni, ment így a tv 1 napig kb,és ugyanaz lett vele,mint előtte. Valami trükk van ennél a típúsnál??? Azt hittem ez volt a gond... és most kiderül mégse. vagy még valami kell cserélni vele párhuzamosan? mondjuk elkókat a körében kidobáltam vagy 8 darabot.. köszi.. sparco
Samsung UN50J6200AFXZA - One side of LED's not working?
Complaint was no display, confirmed and I saw
this series USA model is very prone to backlight failure, so
ordered (8) new strips. Opened up the TV, and am testing the old ones. So
far all the ones on the right side are lighting up ok,
the set of strips connected to them via the connector side with the plugs
are not lighting up at all, even when I supply power directly
to the pins on that side.

I took out a set of the new strips, connected them together and tested, and
they are doing the same thing...whats going on? Thought these were all in
parallel.

If I separate the strips, the one with the connector plug seems to not
light. I have not gone through all the
new ones yet to test. I suppose they could be defective but strange how all
the ones in the TV on that side are not lighting and the others are.

Anyone have an idea whats going on here? indecision
