TV randomly turns on and off repeatedly
I have had my Vizio for a little over a year, a few months ago it started to lag when I changed the volume or channel with my cable remote. We have lost the remote to the tv so it can only be controlled by the cable remote, smartest app via the phone and another vizier remote we have for a TV in the kids room (just realized about a year ago the kids tv would turn off by itself but immediately turned back on).
After this issue the TV started to turn on and off by itself, not just a few times but it continuously does this ALL day, about once a day the TV will eventually turn on and stay on but I don’t hold my breath waiting for this to happen. When the TV turns on the Vizio symbol appears, disappears after about 5 seconds, the screen gots dark and then turns off, this is the ongoing cycle.
Can someone please help, it is out of warranty, we have tried changing all outlets, cords and unplugging and plugging it back in, Tried the method form when the TV is in RGB mode but no success.
Also, when the TV is in its cycle of on and off we cannot turn the TV on using any of the current devices.
Please help, football season is here and this is the one in the living room we use all the time.
