I've been using my m50 for a little over a year now in manual video mode teathered to a PC via an Elgato CamLink and EOS Utility 3 (v3.13).
For several months the usb connection has been a bit finicky and prone to disconnecting from the EOS Utility. Lately I barely touch the connection and it'll drop/reconnect, and often will just randomly decide to drop connection a couple times an hour.
Starting today the HDMI is showing similar symptoms. It'll randomly drop connection or momentarily display a blue cast to the output.
Any ideas as to what's going wrong?
