X1 Carbon 2014 boots with display errors

[KUGA]

Hi,

while running i had problems with the display (see screenshot). So i resetet it.

Unfortunatetly then it was broken and only the keyboard flickered. After googeling a while, i deconnected my battery.

Then it booted. BIOS want a new date (BIOS and OS selection looks fine). However when booted, the display error comes back. Also when booting from a live USB stick.

Now, i cannot get it to boot anymore.
Update: It boots to the this again. Seams it takes a little time between boots. This time the picture froze in the boot log (console mode) with simalar looking artifacts on the screen

Is there anything to repair? where can i get spare parts?

IIRC the X1 Carbon 2014 uses the built-in Intel Graphics.

Does the issue persist even when using an external monitor?
If yes, it boils down to either bad RAM, or a CPU problem.

In the first try, i used an external display via the dock via DVI

Then, to avoid driver issues (the randomly occured in my linux mint) i used only the internal screen.

And yes its with intel graphics
