Schema Tv SEKON

Recommended Posts

  Va salut,

Am un Tv SEKON (fabricat in China).Pe eticheta spate este marcat: SEIKON model S 21N-CPT

In interior pe placa de cablaj mai are marcat :

TH-2105 NF 21"

Are procesor tip OM 8371PS/N3/1, sursa cu tranzistori, cadre STV.

Televizorul nu porneste.Aleator dupa mai multe incercari , porneste si poate functiona ore, fara sa se mai opreasca.

Sursa scoate tensiunile corect (probata prin decuplarea etajului de linii)

Din masuratori, tensiunea care alimenteaza cu 8 v procesorul atunci cand nu porneste, este mai mica de 7v si se aude un zgomot usor in trafo linii.

 Va rog daca ma puteti ajuta in primul rand cu o schema si cateva sugestii.

  Va multumesc si o zi buna.
