| Sziasztok! Ide is felteszem hátha valakinek van hozzá ssb-je. A címben szereplő tv-hez keresek maint. A 1,2v ágon a mosfetek kivétele után is csont zárlat van. Sasszé: q529 1e la. 3104.303.51026 - 3104.313.62146 Egy kép róla: |
Sziasztok!
A kèszülèk nem indul.A sortranzisztort kivéve, helyére 220/60W izzót rakva a sortàp 145V.A sortranzisztort visszarakva a sortáp leesik 25V-ra.
Amit észre vettem 1534/315mA bizti az E/W fokában szakadt. Amít eddig cserèltem C2543/1n, C2546/10n, C2547/22n, C2549/390n, C2550/560n, C2551/1,5mF kondik, de semmi vàltozàs.
Sziasztok!
Egy PHILIPS 20PT1354/58 L9.2 E chassis TV-vel kínlódok.
Nem indul a magasfeszültség.
A táp 95 V helyett 70 V , 9.5 V helyett 6 V.
Táp a hálózati oldalon 100% jó. Sorkimenő trafó , tranzisztor jó. Elektrolit kondik cserélve a sorkimenő körül ( volt még egy ugyanolyan tv )
Próbáltam elkülöníteni melyik a zárlatos ág:
Ha a táptrafónál megszakítom a 95 V betápját a 9.5 V felugrik ( 6 V-ról ) 10 V-ra. Ha a táptrafónál megszakítom a 9.5 V ágat a 95 V felugrik ( 70 V-ról ) 110 V-ra. A 14 V-ot megszakitva nem változtat semmit.
Ha esetleg valaki találkozott már hasonlóval ,ha valami tipikus hiba , nagyon megköszönném ha nem kellene az összes gyanús alkatrészt végigbogarásznom. Főleg , hogy kb. 15 éve nem javítottam , az „újabb” típusokkal semmi gyakorlatom , nem elvállaltam , hanem meg KELL csináljam „társadalmi” munkában.
Segítségetek előre is köszönöm!
