Am schema si am pus tranzistori echivalenti 100 % : irf 9024, irf 024.

Am verificat si am mai gasit 2 tranzistori smd si i-am inlocuit .

Un zenner pe care l-am inlocuit deasemenea.

Am tensiuni pe finali corecte + - 16 v.

Nu mai stiu ce sa masor totul pare ok.

Daca ai mai intalnit defectul te rog sa ma ajuti.

Deci :

Tensiuni corecte, imagine pe 3 sferturi de ecran pe fond de av si cursa inversa si se mai vad 3 dungi orizontale cu cele 3 culori primare.

Multumesc frumos.
