Why is my TV being weird?

I have a Samsung 7 Series Smart TV. Recently it’s started turning on and off sporadically, sometimes only playing audio and sometimes only video. I tried to launch prime video and it randomly goes back between prime video, sat tv, and nothing. I’ve tried the ol’ turn it off and on again and unplug it for a few minutes already.

Thank you in advance!

Hi @ph000 ,

If Anynet+ (HDMI-CEC) is on try turning it off and check if this resolves the problem

Go to Settings > General > External Device Manager > Anynet+ (HDMI-CEC) > set to Off

You will lose some user desired functionality of the HDMI-CEC features when you do this

@ph000 could be a PSU issue but I do not recommend to just willy-nilly changing parts. Remove the back from your TV get your multimeter and measure the input and outputs to and from your power board. Remember that it is your button/IR bar that tells the main board to turn the power board on <simplified>. So in reality anyone of those boards could be the issue. You need to proceed with checking things systematically. Post some GOOD pictures with your QUESTION so that we can see what you see. Adding images to an existing question
