I have an Amazon fire cube and yesterday my tv started acting up. The screen is very snowy and has red and white vertical lines across the screen as well as a green line horizontal across the middle of the screen with little boxes below it. Thought it was my cube so I bought a new one and have the same issue. Swapped it out for an older fire stick not 4K and it worked fine. Both cubes work perfectly on my other tvs. I then hooked up my 4K fire stick and I have the same issue. Is there issues with the 4K I have done factory reset on both the tv and cubes with no luck, changed imputes and tried different settings but nothing corrects it. Was working fine then all of a sudden this happened. Any one else have 4K issues? Roku apps work fine just issues when I hookup a 4K device.

Running into this exact issue today. No matter the hdmi input I use I get lines and issues. Tested the fire cube and hdmi cable on another tv no problem. Tested a Nintendo switch on the tcl and the picture was fine (was lag but that is another issue).
