I’m wondering if anyone has had any problems with this model?? My one has suddenly stopped showing anything on the screen , other than it just keeps changing from full screen white to black and then green , blue , red . Followed by all the Colours first in horizontal and then vertical order over and over . There is the audio from the tv station in the background but nothing works on the remote other than on or off. I know it’s not tuner problems as nothing on external blue ray or 4K players will play either .
