so i have dell 5290 with code board LA-f391p, the problem is cant display, the capslock still on and blank screen no response. but when i try to remove the flexible lcd from the board is getting normal, capslock can response, i tried with external lcd its working. i check in lcd F1 got 3.3v and F2 13V i try with another lcd its working too, but if i try unplugging and plugging it a few times, it sometimes works, if i restart it it comes back like the problem in the beginning.
so im want to ask,
is the problem with the lcd?
or anything else? with board of lcd?
is confused me
