Hello community,
This monitor turns on and off very quickly upon connecting the AC adapter (tried two, tested 19v).
I can see the LG logo on the screen for a split second, then turns off and on constantly in less than 1 second intervals. There's a high pitch noise while the stand by light/screen is on.
I looked at the capacitors, only removed the big one
1NBKJ
33
100V
Measured it, it was fine. Anyway replaced it with a new one, and no luck.
Just to test, unplugged the CCFL. Plugged the AC adapter. It stays on, the high pitched noise remains (some IC? coil?) and I can turn it off manually.
Any help will be greatly appreacciated!
