Hi
I'm have a Samsung LCD tv model LA40A330J1, the problem now I'm facing is the picture in the panel turn to bright white with little colour.
What should i replace or change to get it fix?
Thank you.
Sziasztok !
A fent említett készülék sorvég tranzisztor hibával jött. Tranyó csere után a TV megy csak szélesebb a kép. Impulzus kondikat kicseréltem ( rajzom nagyon rossz minőségű így pozíció számokat nem tudok ) EW tranzisztor mérésre jó kollektorán kb. 12 V mérhető. A sorméret akkora, hogy nem tudom eldönteni, hogy van-e EW szabályozás vagy sem. EW áramkör lekötve és szerintem nem változott a helyzet de nem merem járatni. A sorvég tranyó nem melegszik.
Segítsetek mit hagytam ki.
Sziasztok!
A segítségeteket kérném:
Egy régebbi Samsung LCD TV-ben van a következő Gamma IC, de sajnos a felirat leolvadt róla. A Tv hátlapján sincs tipus, csak egy utólagos cimke, amin DV3 szerepel. Meg tudná mondani valaki a kép alapján, hogy melyik gamma IC van benne?
Köszönettel:
Attila
