Hi all this is a bit if a weird one and probably quite niche but I'm hoping for some advice!
I have a Nintendo Gamecube connected to HDMI 3.
Tried it about a week ago and it worked fine, displayed perfectly. However went to use it today and have an issue.
It detects the device is on and offers to change input to hdmi 3. When I change to it, the screen is just black. Doesn't throw up no signal, it's just blank.
Then after that if I change back to HDMI 1 (My TV Box) that screen is blank to in the same way.
I then turn the TV off and on, and hdmi 1 works again.
If I try the gamecube the issue repeats. It's odd as it worked the first time I set it up. It's as if it knocks out the hdmi's in some way.
Any tips or am I missing something obvious
Thanks
