Sziasztok
A tárgyban nevezett készülék nem indul be csak 3,3V van meg a táp kimenetén. Ha leválasztom a tápról a led driver panel 24V-os ágát beindul a készülék, ha ilyenkor külső tápról megtáplálom a driver modult(800mA áramfelvétele van) van kép, hang. Olyan mintha a táp nem lenne terhelhető. Szűrőkondikat cseréltem táp 12V, és 24V-os ágában.Ötleteket kérnék mi okozhatja a hibát?
Hi everybody, my first post here.
I've found on this site many information and the service manual about the TV in subject, but I stumbled upon a strange issue.
I repaired the earphone socket (pic attached) that had been stripped away and now the TV doesn't power on, it only gives a short beep when you touch the power on button and nothing happens using the remote. I checked the usual things (audio paths, cracked solderings, damaged tracks, power supply, power rails), but I cannot found what's wrong.
Any idea/clue on what to (double) check this time?
Üdv
Hozzám került egy LG 26LB75 típusú lcd tv készülék hibajelenség bekapcsolom a kép felső kb 1/3 a vízszintesen csíkos alatta egy színű szürke.Olyan hatása volt mintha lassítottan de változna a kép.Szétszedtem a tápfeszültségek rendben vannak.A fő panelon elkezdtem nyomkodni a processzort egy idő után bejött a kép normálisan.Most működik kb2 órája rendesen.Hűtőborda nincs rajta gyárilag.Valószínűleg a golyózás elengedett?Kit ajánlotok aki ilyet javít?
