Macbook Pro distorted screen

After 20 minutes I looked again after my opened Macbook which is still sideways on the table hah. I had little hope too but now i saw the distorted screen is there even without having touched it the last 20 minutes. Anyhow tapping on the part of the logic board still makes it worse and you clearly see more flickering then.

I guess the logic board or GPU might be overheated or something like that? I searched the internet and there were people cooking their logic boards in the oven to fix similar issues.

Maybe buying a new logic board would help here but with the old device it's not worth the money anymore. I thought it would be ok if I could get it repaired somehow, because apart from the outdated software it was still running very smoothly. Shame.

Thanks for your quick response. When I open the Macbook and put it sideways on the table i noticed, no problems seems to occur. Can it have something to do with it when pressure comes from the underside because as soon as i start tapping a bit on the Macbook in this area (circled area on the image below), the display starts to show these distortions. Tapping anywhere else in the middle of the board makes no impact.

Edit: Forgot to say if i enabled "Automatic graphics switching" in Energy Saver the mouse cursor started to flicker. Not sure this has to do with it too.

Thanks. Yes it might be time getting a new one.

Hah. So i tried baking it in the oven at 200°C for 7 Minutes after i wrapped the logic board in aluminum paper except for the gpu. However it didn't fix it for me. Still a fun experience :)
