Vertical lines on screen+external display stuck on apple won’t boot

No water or screen damage. Vertical lines on both computer screen and external display. I’ve tried all reset procedures. It will not boot in safe mode. Ran hardware test and it came back with no issues. Is this a gpu issue? or a kernel panic?

Can you post some pictures so we can see things. It would be helpful to see both the internal and external display at the same time (maybe a video) Agregar imágenes a una pregunta existente

Wow! Not good ;-{

I was hoping the issue was the display as that would need a new display.

In this case your video RAM is messed up, this will require either finding someone with deep micro-soldering skills or you’ll need to replace the logic board.

Update (02/10/2022)

Sorry replacing the VRAM is not a trivial job! You need some special tools and access to the needed parts which are hard to come by on the open market.

Here’s a view of the logic board, the Yellow marked chip is the GPU and the four green marked chips around it are the VRAM chips

Shoot. That’s not what I wanted to hear. I took the cover off to see if I could see anything visibly wrong with a display cable or something, and randomly it started working again. I tried to pull up the errors in the console and there seemed to be a lot of gpu, and “google helper” being listed. There was a software update so I started that, and when I came back the screen was black and unresponsive. I held the power down to reset and now it’s back to the vertical lines and the apple logo. Is there instructions that I can attempt with the video ram, before i replace the logic board
