alex26 Posted October 29, 2014 Share Posted October 29, 2014 Buna ziua. Acest tv a avut sursa defecta, 17pw15-8. Dupa depanare, am o imagine cu niste firicele de verde. Respectiv daca in imagine am 2 persoane, una cu parul negru si cealalta cu parul blond, la aceasta din urma se vede prin par niste urme usoare de verde dar in conturul parului ca si cum ar fi desenate niste firicele prin par. Nici nu stiu cum sa ma exprim.Am facut niste poze dar nu stiu daca se observa ceva, le voi posta maine. Sa fie defctul din ecran sau t-con. O parere daca se poate. Va multumesc. Link to comment

leoncris Posted October 30, 2014 Share Posted October 30, 2014 (edited) Ce a fost defect in sursa ? Ce componente ai inlocuit ? Edited October 30, 2014 by leoncris Link to comment
alex26 Posted October 30, 2014 Author Share Posted October 30, 2014 Doar condensatori, inclusiv caramelele C 877 si C878. Link to comment
leoncris Posted October 30, 2014 Share Posted October 30, 2014 (edited) Toate tensiunile sunt corecte si stabile ? Reglajul de culoare nu'i cam mare ? Edited October 30, 2014 by leoncris Link to comment
alex26 Posted October 31, 2014 Author Share Posted October 31, 2014 Toate tensiunile sunt corecte si stabile. Placa mainboard este Vestel 17MB11-6. Am schimbat si memoria 24c32 cu una goala dar la fel. Link to comment
alex26 Posted December 20, 2014 Author Share Posted December 20, 2014 Are cineva un dump pentru acest tv? Mainboard 17mb11-6, procesor pw181A. Link to comment
alex26 Posted February 13, 2015 Author Share Posted February 13, 2015 (edited) Am revenit dupa o lunga perioada cu acest tv. Azi am stabilit in proportie de 100% ca problema la acest tv. se gaseste in mainboard . Pana azi banuiam ecranul, dar am facut rost de un ecran identic ok, cu t-con ok si problema mea ramane, deci exclus din ecran. Problema la acest lcd ramane un contur de verde si tot timpul in alte locuri . Acum ma gandesc sa nu fie din memorie, poate are cineva un dump. Poate s-a mai intalnit cineva cu o problema asemanatoare si imi poate da un sfat. Edited February 13, 2015 by alex26 Link to comment

Guest Posted February 13, 2015 Share Posted February 13, 2015 Lipsa pixeli, Schimba videoramul , Sar putea sa fie chiar impuscat pe verso . Link to comment
alex26 Posted February 14, 2015 Author Share Posted February 14, 2015 Am schimbat si videoramul, dar la fel. Am pus si dump-ul, dar tot degeaba. Link to comment
Guest Posted February 14, 2015 Share Posted February 14, 2015 Cablul Lvds la-i schimbat ? am vazut mai sus ca zici de display si t-con . Link to comment
alex26 Posted February 18, 2015 Author Share Posted February 18, 2015 Da, am schimbat azi si cablul, ramane defectul. Link to comment
Guest Posted February 18, 2015 Share Posted February 18, 2015 Scuze am marcat gresit Videoreamul in prima poza . am avut doar o poza mica . Acum am scos alta si am vazut ca videoramul e ceva mai in dreapta . Intre procesorul video si lvds . Daca-l schimbi si pe ala si tot la fel face atunci ar mai fi de facut un reflow la chipul video Bga-ul . Ai verificat condensatorii de riplu ,sau cu esr metrul ?? sau aer cald Link to comment
