I finally fixed my lcd fujitsu 19-2!!!. The problem is the same reported in a lot of forums: the screen turn black just after 2-3 seconds. I suppose that the problem were the capacitors, so i replace all them (someone were an hermei model, but anyone were bulged and they have the correct capacity). The black screen persisted, until i found this http://warrantyvoidifremoved.com/tft-repair: i use a resistance of 3.3kohm in the same position and the screen now work!!!!! I made some photo of the power board. I also found the eletric scheme, but i don't undestand how it exactly works: the problem is on the capacitor of the integrate ba9741f, probably on the pins used for the feedback error.

I also had corrosion/oxidation on the... -

by turmixHello, I'm working on a new deskmod pc project and have a problem with my monitor, an AOC U34G3XM, well, I may have bricked it.
The monitor was dismanteled and the separate parts parts integrated in the desk. the screen panel alone is on the upper part, and main board/video board + power board on the back of the desk (not enough place on the cover to fit it)

During another reassembly, I made a mistake, and...-
