horizontal lines all over screen

[johnrobert]

Asus laptop G73sw series, high end i7 processor 2 years old
If I move or grab it, I get horizontal lines all over screen then it goes to sleep
When I press power it goes back into Windows and everything is the same as before
Nothing lost
At first I thought GPU but since it does not blue screen or anything and only does it when I disturb it
I am thinking maybe screen cables or something loose.
I was onsite and I should have plugged it into external display.
I dont think this model would have an inverter

1st guess is cable, second is LCD. If it's shutting down then it is sensing a fault which is why I suggest the cable. Also, I'm ruling out the MOBO because it sounds like it is gracefully shutting down, correct?

If moving the screen slightly causes the white horizontal lines then it could simply be a loose cable connection. I have had this many times before. I would remove the display panel and then reseat the cable.

If the screen is LED then you won't have an inverter. If reseating the cable does not fix the problem then it looks as though you need to order a new display panel. I would test with an external monitor first just to make sure the the graphics card is not at fault but I think in this case it will be a dodgy connection or display panel is at fault.
