I've had my Philips smart tv for 2 years and for some reason the TV is glitching out. The TV stopped taking inputs so I'd take out the batteries thinking it was the controller, but I'd look up to the tv and the volume is going up and down on it's own. It's currently https://nox.tips/ at 100 volume and I can't find a way to lower it or find a way of controlling the TV via universal controller. I'm not sure what to do.
