Problema TV Maxwell LCD 26HD TXT (sasiu Vestel 17MB22-2)


Recommended Posts

Va salut. Am in service un tv Lcd Maxwell, model LCD 26HD TXT, sasiu 17MB22-2 si sursa 17PWxx(spun "xx" pt ca nu am gasit o notatie clara pe placa, dar seamana perfect cu seria 17PW de la Vestel).

Defectul se manifesta in felul urmator:

Tv-ul nu pleca din stand-by, toate tensiunile de pe sursa fiind bune.Daca il deconectez de la retea cateva ore, porneste si functioneaza fara probleme, insa odata oprit am aceeasi problema.Mentionez ca am schimbat toti condensatorii electrolitici din sursa, inclusiv C877 si C878 de 15nf/630v din primarul sursei.

Am nevoie de un sfat in privinta acestui defect.Poate l-a mai intalnit cineva.

Multumesc anticipat.
