Vizio E500i-A1 Screen turns to black & white at random times

I have a Vizio Vizio E500i-A1. It’s about 5 yrs old. The picture will show in black & white at random times. I have checked the color settings & it was not the issue. I have to turn the tv on & off a few times before the picture will show up in color again. Is this a common occurrence with this model? Or could this issue be the wiring? Maybe it needs new ones?
