Is it possible for a set tob box to damage a TV?
I’ve bought a TV recently, not two weeks ago, only used it as a secondary monitor. But i decided to add a set top box provided by my cable company. At first stb had booten up and showed life (didn’t used for a long time), but no channels showed. Then i rebooted it and everything was ok. TV ran for about a few minutes and then everything turned green and it shut off. After powering it up, no signal was recieved from stb, so i tried other 2 hdmi ports to no avail. I tried turning them on and off, both the TV and stb, but nothing happened, except that there were random TV shutoffs. I removed stb and continued using it as secondary monitor again. Then TV randomly shut off, and continued doing so every time I turned it on. Also date and time resets like I’ve shut the power off. There are no loose connections, remote is not stuck and timer for sleep is turned off. I’m not sure if this, if it is the case, covers my insurance. What should I do?
