I have an older XU3 that started to display flickering through its HDMI port. Also, there seems to be a color missing. Here's a video of what is going on: https://youtu.be/WofjPlx3GkY
I'm using a microhdmi-HDMI adapter (I've changed it, but the problem persists), and also I tried it on a different TV and with a different HDMI cable.
My question is - is there a known (fixable) defect with the microhdmi port on the XU3? (wiggling the cable sometimes makes the image look better). Any recommandations on what I could do to improve things?
