I've had a katsukity capture card for over 2 years and it's already broken once before and I had them repair it and what not, but I experienced the world's worst customer service (as in, they never told me it arrived, they wouldn't tell me if they had it when I asked, and sent it back without telling me etc etc). Regardless they fixed it the first time around. Now I have a new problem and I want to try to avoid sending the console back to japan, because I don't want to experience that again.
Anywho my current issue is through my capture software, only my lower screen is beginning to change hue everytime I move the console. It flickers and it's irritable as I am a streamer/youtuber, so you can understand I need both screens to be in top condition.
So this is the problem screen

and this is how it should look

I've tried 2 usb cables, both had the same problem. Would anyone know what the problem would possibly be?
Thanks ^^
