Dell LCD Monitor P2412Hb
« on: June 09, 2014,19:12:17 »
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
