My pos Hisense shuts off when the screen is too bright. You probably have adaptive light or the brightness turned up during the day. This TV is the worst.
Sorry, there was a problem. Please try again later.I am responding here because this comes up when searching this problem and I have just had a breakthrough with this issue. I removed the back panel and tested every capacitor (after unnecessarily removing a few of them and soldering them back on). I then realized that the voltage in my old house is pretty unstable. I was just able to test this theory by turning on an espresso machine and a PC on the same power strip and I was able to get the problem to happen again. I cranked the brightness sup and turned off the PC and it went away. If you are searching for a solution to this problem, and you live in an old house, test your voltage at the wall and make sure it is stable when you turn on some higher draw appliances.
