New LCD is fuzzy - Help needed

[dgiles79]

I had a laptop come in that had a visibly cracked screen, but displays normally on an external monitor.

So i ordered a replacement screen using the LCD model number, but it was blurry after I installed it (see attachment). Assuming I had received a faulty screen, I requested a replacement. The replacement did exactly the same thing.

I then decided to replace the LCD cable, but still the same results.

Has anyone seen anything like this before, do you think it could still be the motherboard even though it displays ok in the external? The motherboard is the only other thing that comes to mind (unless I did get 2 bad LCDs with exact same issue)

I suppose I could try reading.. lol

I would also highly doubt that two screens in a row would have the same problem.. I have a test screen for these situations.. Maybe you could take apart an easy laptop and try a known good screen before ordering up the mobo...

For me, when I see lines on the screen like that I find its a bad LCD. Could try applying slight pressure to the "do not touch " tape on back of LCD and see if it changes.

I'm starting to think I might have received 2 bad screens in a row with the same issue. I tried testing with some old broken screens, most of which are too broken to see anything, but I have 1 old screen where I can see the bottom right corner of the screen.

On the old broken one, the Intel logo in the bottom right appears clear, but on the new one the Intel logo is blurry. (see 2 attachments)

Seems strange that I would get 2 new screens with the same issues, but it looks like that may have happened.

That actually is quite possible. It could be a problem with a small batch of screens that where made around the same time. If it is a small number, the manufacturer may not have noticed. I have had the same thing happen with some hard drives that I ordered.

You may need to try a different vendor, or at least have that vendor try a different model. I say this because usually there more than one model or brand of screen that will work for any given model of laptop. We had one vendor send this three screens, all were verified to be good by the vendor, yet all three gave a similar screen to what you show. I ended up using a different vendor who gave us a different compatible screen and it worked just fine.

I ordered a screen from a different vendor this morning, so I will see what happens when it arrives.

I used to order laptop screens form different vendors and hate it when I have to RMA. Now, I only buy form screencountry.com. They don't have the lowest price but it's reasonable. I bought dozen of screen and so far no RMA.
