TV LCD fara imagine

Recommended Posts

Buna ziua , acest lcd de 51 cm Sensy LCD20KAT ( Daewoo Telecom Europe ) are sunet , are lumina de fond data de ccfl-uri dar nu are imagine . Am verificat tensiunea ce alimenteaza t-con si este de 12 volti , modulul t-con este ca la monitoare in partea de sus si pe toata lungimea displayului si pe care am gasit o siguranta smd prin care trec cei 12 volti si nu este intrerupta . Televizorul are un alimentator extern de 15 volti care este ok , pe placa de baza care are codul : PLHM01 , KTV-VER : 050905-NEW , LT201 CH600-MAIN am gasit o serie de stabilizatoare care au tensiunile ok , controlerul video MTL015F Myson Century este cald in limite normale semn ca se alimenteaza . Ce ziceti sint sanse sa fie totusi t-con display defect implicit necesitind schimbarea displayului sau chiar acest MTL015F defect si astfel fiind necesara o alta placa de baza ? Multumesc .

Pe T-Con ai masurat ceva tensiuni?Si acolo ar trebui sa aiba ceva DC-DC.
