Hi Everyone
I'm chasing a service manual/schematics for a DELL LCD Monitor P2412Hb .
It has a problem with it's backlight (LED Backlights in this one).
Problem #1 - Would function ok, until you powered off, then on again. Backlight would not work. Caps checked out ok on the power board, then I replaced a few caps on the controller board that had odd esr results....first power-up, looks ok. On/Off multiple times....looking good, until I powered it off and moved it to my desk...then it failed again. The diagnosis continues.
Diagrams would be a great help.
Regards
Peter

Hi,what IC employs as inverter controller because depending on it it's possible to try to disable the protections
as could be a malfunction of the inverter.
