Omen 17-w200 CTO Display Issue

[Shank236]

Yesterday I started getting an intermittent display issue where it fills completely with barcode like vertical lines.  This occurs primarily when the display is moved forward and back. If I move it carefully I can find a spot where the display works properly. Move it again and the bars come back. (Its working properly now allowing me to post this)  I removed the display bezel and  see at the bottom of the display the cable from the motherboard .  There is black plastic ground protection covering the display circuitry almost the entire bottom of the display.

If I gently touch the ground protection plastic the vertical bars appear...release and get normal display.... sometimes.

It seems to me that the display itself is OK as evidenced by the fact I can still get it to work properly.

I believe the lcd display cable is bad or its connection has loosened. 

The issue seems to be happening much more frequently now and its taking longer to get a good display.  I haven't connected another monitor yet but may have to if this gets worse.

Before trying to tackle the issue I thought I'd see if anyone out there has experienced this and if one of you experts can make sure I'm focused on the correct issue.

Thanks

Hello @Shank236 

Did you try re-seating the cable yet? Sometimes that's all it needs.

It certainly might be a bad cable also, but I would have no way of knowing which one you have since its a CTO model. Depends on which panel you have installed. If moving the cable is causing that reaction, its the cable or port pretty much guaranteed. You could bypass using the built in panel with an external monitor if you wish, yes.

Here is your parts list if you need it...

Thanks for your help Photoray!

No I haven't tried to re-seat the cable.

Looking at the display assembly it isn't intuitively obvious how to get at it.

The steps for removing the display (if that's necessary just to re-seat the cable) look daunting to say the least.

Searched for a video but so far cant find one.

Any advice?

BTW,  with the bars displayed,  I carefully lifted the bottom of the display a tiny bit,  underneath the anti-static tape near where I think the cable connects.  It displayed normally. Let it go,  the bars display. So I lifted it again and slide a small spacer in to stabilize it. Let go and now its fine.

So very possible its just a loose cable connection??

Sounds like its probably just loose. Ill send you a PM with further info.
