Re: All TV’s connected to Roku and stuck. Volume only.
I'm also having this problem. I was watching TV, and it just rebooted. I'm just seeing the splash screen over and over. I unplugged it and tried to do the reset button. Nothing works.
Sorry to read you have entered the twilight zone but there's light at the end of the tunnel. After swapping out the power supply, main board and T -con boards without success I found one LED light out in a backlight strips. All five strips were $30 and all better. Be sure to use the suction cups for the screen and keep it perfectly flat. The slightest bend will crack the screen. Btw, does anyone have an old 58" Sharp screen or TV for sale? Yep, I used the suction cups but bent the screen slightly and now there's a crack.
I unplugged each LEDs one at a time, but no luck. I saw a YT video saying bad capacitors, but all were fine, I still believe its the firmware and I can't seem to find the upgrade so I can do a USP stick upgrade.
During start up one of the tests is of the LEDs. Until all LEDs pass, it reruns the test..when all LEDs pass it continues to the next test. A LED tester or 5v generator will show the faulty LED. Replace the one LED or strip and the problem is solved.
I understand your thinking because I kept thinking the same thing. It couldn't possibly be this simple but it is. As soon as I replaced the strip with the faulty LED all the LEDs lit and instead of starting over it continued past that point.
