Üdv.Mindenkinek,
A fenti készülék került hozzám működésképtelenül.
Korai öröm volt, hogy a sec. oldali elkok felrobbantak.
Csere utáni mérés, leválasztott scalerrel: a primer táp megvan, a secunderen kb. 1hz pulzálás mellett megjelenik az 5v és a 15v.
Primer elkok is cserélve.
Ha ráterhelek az 5v-os ágra egy 6,3-as izzóval, akkor stabillá válik az 5 és a 15v-os ág is és az optocsatolónál sem mérhető a ingadozás.
Ha rádugom a scaler panelt ismét elkezd ingadozni a fesz, villog az izzó. Cseréltem a scaler-en található elektrolit kondenzátorokat is, nem segített.
Minden segítséget előre is köszönök.
Üdv.
Tux

Fent említett monitor(LB880BU) működik,de a képe kicsit zizeg,mintha hagyás lenne.
A fehér szín is kicsit szürkés,a tft képernyő fáradt el benne vajon?
Hogy lehetne ezt meg szüntetni?
Inverter trafót keresek LG W2243 monitorba.
