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

Sziasztok!
Tudnátok ebben segíteni?
Zárlatos volt az egyik videovég, cseréltem mind a 3-at, de csak
csak raszter van.
Cseréltem eeprom tartalmat, de ugyanaz.
A katódokat leraktam testre egyenként , virítanak
A TDA4780-n a következő DC szinteket mérem:
14 pin 0,7V
15pin 4,1V
16 4,5
17 4,4
18 1,2
19 2,5
20 0,7
21 1,9
22 0,7
23 1,9
24 0,7
25 1,9
Megszkopoltam a TDA4780. A SC-t megkapja a 14 pin-en , a hajtást is .
a 20, 22, 24, gyakorlatilag semmi nincs, ezáltal a videovégek 9 pin-en sincs jel. A
19-en van valami 2 Vpp jel, de tv miniscoppal csak hasonlít.
Szereztem egy TDA4780-t de azzal is ugyanaz.
Itt egy rajz:
