My Onn Roku TV's display just randomly went crazy and now has lines all over

I was just watching one of my favorite shows when suddenly my TV went crazy. I cannot make out anything on the screen due to the vertical lines all over the display. I tried unplugging the tv and waiting, resetting, and every other techniques I've read online and I have had no luck.

See https://community.roku.com/t5/Discussions/White-vertical-lines-on-Screen-with-sound/m-p/649773#M1546...

It's probably the rare TV hardware problem, not a common Roku software problem. You probably need to talk to the tv manufacturer for support (if it's still in warranty).

If not in warranty, google about it. Apparently these tvs only have 5 modules that are relatively easy to replace (can be bought on eBay maybe). There may be a video explaining how to do it, which module to try first. Could be that a ribbon cable (connector) needs to be reseated.

There should be a pinhole reset button on the back of the tv. You could try holding that down for 20 seconds and reset the tv. (I don't know if has to be on while doing that). If that doesn't fix it, then you probably have to do the above. One downside to trying this is, if it's a hardware problem that won't fix with a reset, then  you lose all your settings. That might not happen if you re-seating the connectors fixed the problem, for example.

I had that happen with two television. One is Roku Onn. It only happens when I turned the heater on. I unplugged television and was fine in the morning. Be careful with how much power or lack of can cause a problem. Wait don't throw out that television.
