Polaroid Flat Screen TV not working

since the self generated menu displays ok id say you don't have a monitor problem , could it be that maybe somehow it got switched over to maybe an "open" input port (example: hdmi-2) as this would explain things a bit , also when you tried the other tv did you use the same cables to connect it as the non working tv ? as that also would explain things

I had similar problem with my Polaroid 42 inch. The screen would be fine for 10 minutes or so then go black. I found a work around that solved my problem and maybe you can to. What I did was remove the back panel of the TV. Make sure it is unplugged first. You should be able to see the electical board. Somewhere on the board may be a switch that says "Burn" or something with "Burn" in it. I set the switch to the "Burn" setting and the TV has worked fine ever since. Good Luck.

Sounds like a bad capacitor on the power circuit board. best place to look

Try several different inputs.

It sounds like you dont have the right HD box. When connecting HD you will use an HDMI cable or a component cable consisting of 5 cable total 3 for video two for audio. Coax cable is not used to connect HD to your TV / Monitor.

try the diffrent inputs HDMI Composite component and see if the video comes on there are 4-10 diffrent inputs on these sets and make sure you select the right input on the menu the remote has a button for inputs a menu comes up and make your selection from there for the right input that you have connected to the tv most menus have TV (air) HDTV (air) video 1-6 HDMI and VGA
