Sziasztok!
Lenne itt egy LG T710B monitorom ami nem kapcsol be. Szétszereltem és azonnal feltűnt, hogy a C774-es (160V 47uF) számú kondi kifüstölt ezt kicseréltem de továbbra sem semmit nem csinált. Elkezdtem mérni a panelen és rábukkantam egy meghibásodott mosfetre (Q719). Ezt is kicseréltem. Így már ad némi jelet magáról. A zöld led pislogni kezd és a panelen lévő relé ki be kapcsolgat.
E probléma felderítésében kérném a segítségeteket.
Előre is köszönöm a válaszaitokat!
Ebből a rajzból dolgozom: http://data.manualslib.com/pdf2/42/4183/418212-lg/t710bh.pdf?44d2aecc759ad522a05cc82a9da81737
Üdv.
Ha a fenti mocsihoz valakinek ha van SM-ja legyen olyan szíves küldje el nekem.
A sortranyó zárlatos volt, a táp csak "cuppogott".Tranyócsere után elindul a táp, de nagyfesz nincs, demagnetizálás nincs, halott szegény.
Igaz gépre nem tettem rá, de 1 pillanatra gép nélkül is indulnia kellene.
LED se világít.Várom a tippeket.Sehol semmi?Nem találkoztatok ezzel a moncsival?
