Horizontal “tearing” every few seconds then returning to normal. I suspect a sync problem but it would be nice to know which circuit board is causing the problem. I am going to try to attach a video of the problem.
@btidmore make sure that you try all input sources and use a new HDMI cable if that is what you are using. This could be an issue with the main board as well as the panel screen rolling is commonly caused by their Gate driving side (supply/signals line) on the panel driver boards. The signal comes from the T-con board. If you want to , check the voltages on your T-con board. You would be looking for VGH,VGL,VDD,VCOM,OE,CPV,STV, and of course ground. If those are good it’s most likely the Gater COF but we will need more info and results:-) Let us know what you find. Depending on your TV there may not be a separate T-con board but it may be integrated to your main board. I’d go with a main board first. Let us know what the model number for this Vizio is
