Incearca sa porneasca de 3 ori si se opreste. Apoi nici ledul nu imi sta aprins. Iam pus bec de 60w pe colectorul final linii scos afara. imi sta becul aprins si am tensiunea 140v si in bord imi apare (88). Telecomanda nu are nici-o influenta asupra lui. Va rog frumos sa ma ajutati si pe mine cu o informatie

Nu cumva sa fie alterat continutul memoriei daca afiseaza 88.

Aveti de schimbat condensatori electrolitici (mai intai cei amplasati pe secundarul sursei langa trafo chopper). Uneori se chiar pot observa care trebuie schimbati fiindca curg si pe partea cablata se vad lipiturile la terminale cu o cocleala de culoare verde inchis.
