I purchased a Gana 3 in 1 hdmi switch to use with my phoenix and regular CV. So as to avoid having to plug and unplug the phoenix back in so it would start correctly. I had it for more than a month. I am wondering if its going bad. I was playing DK jr on the phoenix and the cart was glitching. cleaned the cart with contact cleaner. Still glitching. Put it in the regular CV, same issues. Then I noticed my screen would go black as if I was powering up the unit for its 1st use of the day., I removed the switch and played the same cart for a bit on each console,= NO issues. So my though is that maybe the switch is going bad. There is no external power for the Switch it just plugs into the slot on my TV. Any ideas:, Thanks
