After the security update three different ONN tvs I have all went black. ONN walked me through all of the things I had already tried but to no avail. Before anyone says backlight, the ONN splashscreen is in perfect brightness before it goes black. Any suggestions?
Three?! Yikes! The only thing I could suggest is to factory reset one of them to see what happens.

I have factory reset and power drained all 3. Will never buy another ONN again. Barely over 2 years old. Will probably go to something without being combined with an android operating system as well.
