Buna seara si Craciun linistit la mesteri.Am primit un tv beko cu tda 8362 jungla,pca84c841p/254s1cu urmatorul defect:la pornire tv-ul functioneaza bine ,dar dupa 20-30 secunde isi pierde imaginea,ca si cind ar ramine fara antena,1-2 secunde apoi  revine la normal,si tot asa,mai functioneaza 4-5 minute apoi dispare o secunda .Dupa o masuratoare sumara am gasit ca tens varicap  variaza in momentul cind imaginea dispare.De ex.am tvr1 la 19volti,iar cind dispare imaginea  Uvaricap urca la 22v,ptr o secunda apoi revine la normal.Rog frumos o schema  .

Multumesc.
