Vizio TV's are garbage especially since Walmart took over
I have 4 Vizio TV's. One is 6 years old, two are new, and one is about a year old. The 6 year old one worked fine until this summer. Even the year old one was okay. Then summer comes and they all do crazy stuff. They all have the same crazy stuff.
I turn them on, and get nothing but backlight once a day. I turn them off and on and they work.
I go to turn them off, and the remote seems to be dead. I find the panel button, it also gets ignored. I have to pull the power plug. Then they work for a few days. Then same crap.
When I switch inputs, I get prompted to sign in to Walmart on a 6 year old TV I bought elsewhere.
If you do a factory reset on the 6 year old TV, it lets you know you're still keeping the buggy latest release firmware.
My next TV will be some other dollar store brand I will never ever give it internet access. I will get some external Roku adapter. Vizio Free TV access is no better than Pluto Free TV, and Pluto doesn't jack up my firmware.
