EOS 6D Mark II top LCD screen scrambled - camera not working

[shadysamsf]

After leaving my camera on in video mode all night, I see this in the morning when I replace the dead battery. While it was on it was not recording video.

No matter what I do, the camera does not function and the top lcd screen is scrambled and looks like this. Doesn't matter whether I power the camera on or off, the screen remains like this as soon as I insert the battery and close the battery lid. In this state the camera does not work. It did work like normal once but now it's back to being this again.

Any help/advice is greatly appreciated, thanks in advance! c:

So I ended up selling my 6D Mark II. I had it repaired, but the process took longer than expected and the repair was not what I wanted - so I sold it.

I had Chinese parts ordered. Both the motherboard and power supply module were busted. The Chinese motherboard did not run the camera smoothly since the photos and video footage looked a little blurry. By then, I realised that I'd never get the same 6D Mark II experience, so I sold it.

And life goes on.
