Thank you [USER="132583"]CapLeaker[/USER] & [USER="519980"]vf fa[/USER] !
Sadly, I'm not an electric engineer or the like, so I can't open up the monitor and mess around with it. I only posted here because you guys are the only one's who were able to fix this.
I tried blowing some warm air with a hair dryer through the ventilation holes, but it didn't help.
In case perhaps there's anyone in Berlin who could help, I would be very grateful. I'm sadly quite poor

Cheers.CapLeaker...

Hello. Signed up for this forum to post this. I hope it isn't wrong to post in this thread, but it's exactly my problem and only two months old.

I also have the "four-yellow-one-blue-blinking" issue with an EIZO monitor, but mine is (or was ☹ ) a CG277.
You're the only person on the internet I could find who was able to fix it. I found the problem mentioned a few other times on other forums, but no-one ever get even remotely close to anything. Not at all like what you did here.

Problem has been going on for a while. Monitor works perfectly fine for long,...
