Vertical colored lines on half the screen other half is black, how to get to Roku home page?
I have a Sony 65 inch 4K TV and a Roku Ultra connected to my Yamaha ARC Receiver. I've had this problem before but I can't remember how I fixed it. When I go to turn on the Roku player all I get is Verticle colored lines on 1/2 of the screen the other half is black. I've tried re-pairing the remote with the Ultra, unplugging the HDMI cables then plugging them back in, but when I checked the input and switched from HDMI ARC to a regular HDMI1 I get a black screen but it's like the Roku home page is right behind it because I can hear the noises the Roku makes I.E. the home sound, the back button sound. The only thing I haven't done is replace the HDMI cables which I don't think that's what it is.
I've had Roku on chat and we had tried everything but they don't have a clue, and actually ghosted me on the chat. So, I'm at my wit's end, but one thing I can say is that it might be the receiver. Has anybody encountered this problem?
