LG 32lh510U tv készülékkel kapcsolatos kérdés(ek)
Jelenség a következő:
"lilás" háttérfény bekapcs.után/ 

TV rendben üzemel minden részében egyébként.

1./ Main board típusa LD67B EAX66826106 (1.0)

2./ ennek van egy  IC501 része : olyan mintha a 19VDC-ből nem állítana elő a háttér LED-ek-nek (2 csík sorbakötve) nagyobb , csak 19V feszültséget.
FET-et "jónak" mérem IC501-ből 23láb mintha nem jönne ki semmi kapcsolójel (Szkóppal) 

3./Az  IC501 EN1 illetve EN2 rendben (megkapja bekapcsolásnál )   L503 (ezen kellene létrejönnie a nagyobb fesz.nek) OK, nem szakadt

Ha van valakinek ilyen TV-je, mérje már meg a LED-re mekkora DC-fesz.nek kellene mennienormál üzemben  (pl c505 4.7uF /50V    , de a párhuzamosan c506 33uF/100V )

Van e valakinek próbára egy ilyen MAIN Board-ja?


Előre is köszönet
