Flickering blue and hdmi out not working on my M18x R2

Hi all. Been a long time lurker and all the info has helped a lot so first off thanks for that.

So I have been a M18x R2 owner for about 3 years now. Got lucky and snagged one for a great price it needed a little TLC and I got it up and running. Everything was all great until about 6 months ago I started to see a problem with the colors being off with the color blue what looks like bleeding or tint and flickering. It's not a physical issue as the HDMI IN from any device does not have the problem. Then the HDMI out has recently stopped working. I haven't tried the VGA or Mini DisplayPort out yet as I don't have the cords yet.

Anyone else having or had this issue? I have a feeling it's a hardware failure issue. Thanks in advance!
