Lcd fujitsu b19-2 black screen fixed

[paciarie]

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.

PS: someone else has had the same problem? I add that I have not replaced transistor, integrate but only the original capacitors.
