My TV, [onn 43 inch 4K Roku TV] when on first power-on will just flicker white for a few seconds, then look like a internal glitch, or just sort-of resemble the main menu, but glitching fading into black. I have let it sit unplugged until 4 pm today, and before this issue has happened, random lines had appeared on the TV, all vertical. This has happend only with this TV, and i dont know how or why. Anyone can tell me how solve this?
You're going to have to contact the TV manufacturer.
