I just remembered when I was a kid(Im on my 30’s now) we had this old “box style” television. As it got older, there were times that a white thing will appear on the screen. You can still watch the show but its annoying. Imagine watching your TV while having a white curtain in front of it. One day, I got extremely furious because I was watching Smackdown and slap the side of the TV. Then, it returned to normal. I kept doing the same solution I discovered every time the white thing appears on screen until one day it stopped functioning. 😂

Could be any number of problems, mainly loose connections that are not quite making solid contact until moved. Old equipment had mechanical switches and controls that would get oxidation, which doesn’t conduct electricity. That’s what caused static when turning volume controls, or switching channels, etc. Often, you could turn the control a bunch of times, or switch back and forth repeatedly, and it would break through the oxidation and work for a while. A technician has a spray bottle of contact cleaner/lubricant handy, and will spray it into the back of the controls and move them around, breaking off the oxidation and protecting it for a period of time.
I repaired stereo equipment for several years long ago for a large chain, so I’ve had a bit of experience.
