Unfortunately that didn't help, it was different though. First I saw the
corruption as before, but after a second or two the screen turned blank, like
it didn't get any signal.

I caught a glimpse of some text that was printed just before the corruption,
don't know if it is related or not, just throwing it out there.

It's said "mei_me" <some text I forgot> <something about write failed>

I have seen it before but then I didn't have time to see what it was.
