Buna ziua, Va rog, o idee. In format imagine 4/3 tv-ul se opreste cu sau fara imagine.In format 16/9 functioneaza perfect dar, chiar si asa , cand tastez service mode, imediat ce apare titlul, se opreste. Are procesor tda 9345ps, mem 24c08 smd, rescrisa din nou cu dump original. Multumesc.

Da.Mentionez ca atunci cand se opreste, ledul ramane on, clipind de 3 4 ori. Numai dupe ce il opresc de la retea il pot porni.

:rade:!!! .... ce coincidenta. Si eu am grijă UNUL sunt defect Acelasi. Am schimbat conzii DIN Sursa si cel de 100uF DIN BV, sunt refacut CEVA lipituri crezand ca-i Rezolvat. L-am Lasat fara capac, IAR dupa aprox.1ora sa oprit, dupa repornire sa mai oprit de 2 ori la ONU Timp Foarte Scurt ..... merge acum IAR.! Am altceva în LUCRU si sa-l pun pe banc IMEDIAT, .... se tăia ca este CEVA tipic la ACEST Sasiu. Cand se opreste, tensiunea pe B + este134v.
