3 Why is my tv turning on then off then on then back off?
So the tv is turning on, the vizio logo appears then instantly go black then it shows the screen again like its on a channel then back off. Tried taking out the batteries in the remote, unplugging it and back in, unplugged it and held power button for 1 min and plugged it back in, pushed the power button like 20 times or more, tried a different controller, all same results over and over again.

Ok @oldturkey03 I just got the new board in, hooked it up and now the (power) white light stays on for maybe a second or 2 longer and has a little slower fade but the picture does the same thing except now I don't see a second flash. I even unplugged the video ribbon cable and same result.
Es esta una buena pregunta?
@helpmeplease_20 do you have any audio? When you say your TV turns off does it turn off or is it just your screen that turns black? What does the power LED show? When the screen is black shine a flashlight beam at an angle against the screen. See if you can make out any shapes etc. When you "unplugged it and held power button for 1 min and plugged it back in, " did you disconnect All Devices? Firestick etc as well as cable or sat box?

When your TV is repaired, make sure it is well ventilated to avoid it overheating.

@oldturkey03 Ok, so I just replaced the main board and still doing same thing. Posting a video now.

@helpmeplease_20 shine a flashlight beam at an angle against the screen. See if you can see the Vizio symbol or anything else on this screen. This could be a backlight issue since it flashes quickly. Looking at your Power LED it actually turns off and back on. Since you already replaced the main board you need to check your power board. Typical Vizio, nothing easy :-)
