Why is my device constantly power cycling?
Hello all,
ANSWERS:
"@blairr219 try the whole restart thing again. Remove everything connected to your TV (including Fire Stick, Sat, Cable box, sound board etc.). Then disconnect the power plug to the TV. Hold the power button depressed for something like a minute or so. Now connect one video input source. Stay away from fire stick, cable box etc. but use a local source. Something like DVD/BR/Game console. connect it and then plug your TV in. try to turn it on and see if that made a difference. If it did not it is most likely a power board or main board issue. For that you will have to remove the back cover and take a god look at the boards etc. for any obvious damage. Post some good pictures with your question so that we can see what you see. Adding images to an existing question
Remember that Vizio doesn't care for any DIY repair and will be of no help to this. Schematics are rarely available etc. so we are on our own with that one :-)"
