HP mini 110-1020NR no picture on lcd

[primoz1]

Hi again. I got HP mini 110-1020NR, laptop work fine on external monitor, but on primary just turn backlite ON and no picture.

see video http://tinypic.com/r/6zq17a/5 and http://tinypic.com/r/307p15y/5

I suspect the gpu chipset or lcd cable.

Any idea how to fix this ?

Thankyou.

Hi. Meantime I do one test, take apart complete laptop, with finger push video chip down on board and try turn ON, and picture show up OK.

So I will reball the video chip, and then must be all OK.

Thankyou again.

What GPU is that? I haven't searched much but I doubt they'd pair up an Atom with nVidia or ATI...

Ensure you have seated the board correctly, if it's being stressed when put into the case it may break the balls.

It's got Intel chipset. I'm unsure why you're even trying to reflow it.

Hi. @b700029 It's Atom and Intel QG82945GSE chipset. I think you are wright, maybe is board bended when put on case.
