Címbéli LG led-tévén (42LN5400ZA-BEEYLJG ; chassis:LD36B) nincs stand-by sem. A led háttér tesztelve, ok.
A táp kimenetén csak a 3,5V mérhető (12V, 24V hiányzik), a Power-On vonalon sem jelenik meg semmilyen feszültség indításkor.
Táp: EAX64905301 (2.0)
Main: EAX64891403 (1.0)
Az a kérdés, hogy hogyan tudom tesztelni vagy eldönteni, hogy a táp vagy a main a rossz?

Sziasztok!
Ma hozták ezt a tvét, hogy nincs kép csak hang van. Szétszedés után kiderült meg van szakadva egy led benne, a másik meg nem világít. A szalag típusa: Innotek POLA2.0 32" A, Rev 00 , TIS-4A V-0 , maga a leg 3*3 mm. Típust és beszerzési lehetőséget keresek.
LG 32" LED - model 32LV2510.
The TV shows power but baclight is not ON.
I checked 24V from the power supply and its there.
I chechecked the Inverter/ON voltage and its there 3.3V.
I took a torch and tried to illuminate the screen - I could see the OSD, if I press the menu - it comes up etc.
I don't think the backlight is faulty.
Between the power supply and the main board - I am missing something.
Please help.
Sziasztok!
A fent nevezett tv-n csak felül van kép, alul csíkos. Mi okozhatja ezt a jelenséget? Egyszer már javítottam ezt a tv-t, akkor nem volt kép. T-CON panelt kellett cserélni. Létezik, hogy megint a T-CON panel ment tönkre? csatolok egy képet a jelenségről.
