Az alábbi gondban vagyok:
A képen függőlegesen megjelenik egy széles esetenként dupla széles sáv, ahol a kép hibásan jelenik meg.
A számomra az az érdekes hogy a képernyőn a "teli" színek hibátlannak tűnnek.
Pl. Kék, zöld, sárga, piros..
Viszont a teli fehér esetében már nem ez a helyzet...
Akkor szemmel látható a hiba.
Ha nem csak teli fehér, hanem a képen látható függőleges vonalakkal megspékelem, az adott részen a szín is megváltozik, és dupla széles lesz a sáv.
Ez a hiba előjött, majd fél napra eltűnt és minden rendben volt.
Most néha jó, de csak max 1 percig, és azután újra ez a hiba.
Van valakinek ötlete hol keressem a hibát?
Üdv, Sándor
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.

Van egy Videoton TS5355 TV-m ami elkezdte ezt a hibát:
Hidegen bekapcsolom, akkor magától pár másodperc múlva kikapcsol, majd pár mp múlva be, majd ki majd be majd ki majd be....majd ki...ha ezt 3x eljátsza akkor megy akár egész nap.
Mi lehet a baja? Táp? Készenléti táp?
