SalutAm la reparat un TV Freedom al unui prieten cu urmatoarea problema: Imaginea nu are luminozitate deloc, la intuneric se mijeste cevaAm verificat filamentul, tensiunea de filament (chiar am marit-o strapand rezistenta in serie) nimicAm pus catozii la masa si se vad culorile dar tot fara luminozitate albastru nu se vede chiar delocTensiune FIT este, tensiuni pe grile bune si reglabile din trafu de liniiCe ar mai putea fi ? Eu suspectez tubulAs mai putea face vreo verificare inainte de a incerca cu alt tub? Multumesc
