Out of nowhere, when I opened the laptop during the day there where colored/black stripes/bands over a part of the screen. Nothing special happened to the laptop in the mean time, no impacts or flexing.
The symptoms changed over time. The left side showed weird artifacts and now seems to have a horizontal black line every other line. The right side is now almost completely black except for some subtle dark blue lines.
The issue is also visible in the grub screen and a restart didn’t help so I’m pretty sure it’s a hardware issue.
Not quite as bad, but I got my 11th Gen Framework last Monday. Spent a couple of days setting up and on the Wednesday morning - the first day I properly used it for work - I realised it had a one pixel height horizontal line running the width of the display, and a small blue line on the right hand side. I also tried reseating the cable and removing the bezel. Support were great and after two days back and forth with some troubleshooting and some images they shipped out a replacement which I fitted today and works great. The only reason for the back and forth was because I’m not in the same timezone as the support team.
However, like you my laptop had no physical stresses. It was on my desk and the only physical movement was typing on the keyboard and opening the lid.
I cannot fault support - but I’m concerned as to the resiliance of the screen.
I bought my DIY AMD Framework laptop 13 in February 2024.
After 3 months of using my laptop every day, I carefully closed the lid (as usual) and reopened it 30 seconds later to see the left 1/4 of my screen was almost full of large black strips and thin coloured lines which, for some, flicker back to life or change colour when I move the display of even lightly tap my desk.
I instinctively restarted (hoping it was a software issue) after removing the expansion cards and bezel for good measure. Unfortunately, as I suspected, it was a broken display.
I suspect there are broken traces in the bottom part of the LCD panel which supplies electricity to the individual pixel columns (and rows). In my case, only the left quarter of my screen was affected while it was the right most quarter and 1 in every 2 rows in @Peter_Uithoven’s case. This indicates that some parts were very fragile or previously broken and the electrical traces were severed with a simple lid closing, but I do not think it is a common problem as the only other thread I found was potentially a software issue (on reddit).
After a lot of back and forth with Framework’s support where I gave a lot of details and pictures (probably too much, but they kind of asked for it ), I received a replacement display kit and was asked to send the broken one back. (I did get used to working with only 3/4 of my screen for a week).
It has been 3 months and I did not hear back from them after that. I was hoping to get a followup email for what they found with the display kit I had sent back.
Some things to consider (which did not bother framework’s support):
I have stickers all over the lid which I did not need to touch (and the replacement display kit, being only the LCD panel not the top cover, I still have them).
I 3D printed an expansion card for my mouse dongle.
I often use external monitors, 65W and 100W 3rd party chargers.
I had to reroute correctly the display cable for the bezel to fit correctly on first assembly, but I had never unplugged the cable from the mainboard.
If you are interested, here is what Framework's support asked about:
When I started facing the problem. Any changes or modifications to the laptop. Any 3rd party external devices used and send picture or exact model (e.g. e-gpu, monitor, hub, dock, power adapter, etc.).
Pictures of the entire display while on the BIOS menu (UEFI, but whatever). (pressing F2 during bootup)
Pictures of the entire laptop with different angles (left, right, top, bottom, front, and back). (illustrated)
Any available external display to test if the issue also occur on the external monitor (to make sure it it not software related).
Reseat the display cable. (illustrated and link to guide)
Picture of the display connector “to make sure that the connector on the mainboard is intact and free of defects”.
