Recommended Posts

va salut.la acest tv am probleme cu finalul linii care prima data mi s a ars dupa 1 ora. am crezut initial ca bu..ul nu a fos bun. am masurat din nou tensiunile care erau ok. am pus alt bu cu intentia sa l tin in probe si sa vad daca se incalzeste excesiv. deci l am schimbat a pornit si i am pus sasiul la loc. cind sa l bag in priza...surpriza..tic...tic..tic. daca cineva a mai patit asta..il rog sa ma ajute si pe mine cu un sfat..mentionez ca condensatorul c 602 l am schimbat de la inceput cu 47 micro. spor la lucru.

intradevar..c ul de 47 nu l am verificat de nou dar ramine o intrebare care ma framinta. Cum de sa ars finalul cind doat am alimentat tv fara sa dau on si sa plece liniile? sa fi fost deja alterat cind l am oprit? asta nu inteleg..acum pun un cond de 22 cum este in schema si ma apuc din nou de masuratori
