leoncris Posted October 3, 2012 Share Posted October 3, 2012 Daca'i al tau tine BF_urile aproape , daca'i pentru client , schimba'le. Quote Link to comment Share on other sites More sharing options...
Th3_uN1Qu3 Posted October 3, 2012 Share Posted October 3, 2012 La cat costa, schimba BF'urile. Al meu avea defect finalul linii din cauza unui cond electrolitic pleznit, si la nici 2 zile dupa ce am schimbat trz linii, a inceput sa'mi dispara verdele. Am schimbat si BF'urile si de atunci e ok.O problema asemanatoare cu a ta am avut si eu initial - doar ca la mine era pe albastru. La fel, aveam rez de 10k intrerupta in colectorul trz video respectiv. Quote Link to comment Share on other sites More sharing options...
