Sziasztok!
Említett készülék bekapcsolási kisérletkor villant párat a leden, majd visszaáll készenlétre. Ez idő alatt (amennyire mérhető) minden feszültség megjelenik. T-con ledje is villan egyet.. Gombról/távról is ugyanez a jelenség. Igazából olyan, mintha zárlat miatt nem engedné indulni, de ilyet nem mérek sehol. Van ezeknek esetleg valami jellemző hibája ami okozhatja?
Köszönettel: Kiss Z.

Hello,
I have this LCD TV which has a very white screen, the picture is visible. I could not find any fault on the CCFL Lamp inverter and was suspecting the T-Con panel of failure. The T-con panel is integrated in the control board. What i did is using "freeze it" cold spray i sprayed one of the IC's and it cured the fault. Perhaps the IC needs to be replaced. The part number is AS15-G. This component is not available for purchase in south africa and i would need to import it from china. This part is a LCD voltage buffer.
Regards
Angelos
