GPU issue! Blank Screen but external monitor Works
I got a HP Probook 4520s for repair
At first there was no display at all nor back light. and connecting to an external monitor show grey horizontal lines. windows will load as normal as i can hear the windows sound
then i did a reflow the gpu and when i turn it on. the back light on the lcd turn on but no image and when i connect to an external monitor i working ok and booting in windows..
does it need to reflow it again to see if it solves the problem or a reballing is needed
Questa è una buona domanda?
