Bad Laptop Screen Or Bad Laptop Graphic Card

by amiina9100 / February 22, 2016 5:42 AM PST

So here is the problem i encountered with my laptop.

The screen went silver with some gray vertical lines on it. It was on and working and the screen just went silver. I am trying to figure out is it the graphics or the screen that is bad. I connected the laptop to external screen and everything works fine. I unnistalled the drivers and the screen just went completely black. I connected it again on the external screen and everything works. Then i installed the drivers back and the screen went the same silver with gray lines.

How can i tell is it the graphics card or the screen that is bad, how can i test it ?

Professionals change the cheapest part first, if they can't find the cause.

My guess is that it is the screen.

That was my first thought when it happened but maybe someone knows something more. Thanks for the answer

Nod to cheapest part first.

Sometimes the laptop will give you a further clue if you plug in some external display and the content is scrambled there as well. That points to other than the display.

external display works fine

First thing i did was to connect it to external monitor and it worked fine. The screen is bright therefore the backlight probably is fine , and the inverter probably works fine also. I was looking for some diagnose test to be sure that the display is bad. Thanks for the answer

In service centers we swap in another display to know this.

Too bad the second display wasn't corrupt, then it points at the motherboard. You still have a chance it's the motherboard but it does lean to display or connections to from the display.

What kind of screen should i try and see
by amiina9100 / February 23, 2016 9:17 AM PST

That is a reasonable thing to do. I have Asus R510VB laptop and a couple of VAIO and HP.
Can i use theirs screens to swap with the ASUS and see if they work? Or i can only with the same type of screen that ASUS uses ? (probably the port where the flat cable enters should be the same or there is more to it ? )

There's not a lot of interchangeability there. I have to have the parts for the model that needs repair.

The sources I've used over the years are ebay in a pinch to buy brain dead models with good screens, Asus,com has been good for us in the USA on parts (surprisingly so!) and then we have and those companies that put up YouTubes on how to change displays.

Hope that helps.

amazon and ebay but with no result. Laptopscreen is my next step. However the model i have is Asus R510VB-XX030H which is very hard to find ( at least to me ). i've tried half a dozen of spare parts suppliers in germany and sadly i didn't find anything for that model. Anyway you've been very helpful. Thanks a lot for the info

It also could be the cable
by orlbuckeye / February 24, 2016 4:35 AM PST

that runs from the base of the laptop to the screen. I had that happen to my laptop. But if an external screen work it isn't the graphics card.

Very true
by amiina9100 / February 24, 2016 9:37 AM PST

I did reconnect the cable from both ends ( the motherboard and the display ) and it stayed the same. Also i tested the graphics card and everything is fine. It seems the display is dead.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
