TV Thomson 21DX210S nu porneste


Recommended Posts

Buna ziua!Acest tv are sasiu icc17 si ledul rosu sta aprins dar cand dau sa porneasca se aude un sunet ca si cand ar vrea sa porneasca

,dar pica iar in st by.Pe dioda dp80 care este filtrat cu un condensator de 100uF la 200v se formeaza o tensiune de 70V.Care pica dupa 3 secunde.Mentionez ca in prima faza am gasit trafo linii in scurt.Am masurat si impulsurile cu un osciloscop dar nu prea au forma buna.

Ce poate fi ?Nu am gasit diode in scurt.Am pus FBT40811.In loc de orega 4033053.Va multumesc
