Sziasztok! Van itt egy 4 eves VIVAX TV-2908PF (68cm-es kinai tv, chassis PH02), sorkimenoje: BSC25-N0707, HR megfeleloje: HR80365. Na most az a gond hogy nem lehet beszerezni, a TV mukodik de csapkod at a szikra a kaszkad reszebol a 1.5cm-re levo tap hutolemezere, es amikor mar sokat csapkod akkor kiegeti a biztositekot. Van egy hajszalvekony 5mm-es repedes rajta, mivel lehetne leszigetölni, ha ez egyaltalan löhetséges?
