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. 😂

In the old Tube TVs, the individual tubes were plugged into sockets. The sockets would sometimes get an oxide layer (especially in humid S TX) and cause problems. Dad would remove the back cover and wiggle every tube in its socket, and it did the trick. Like others said solder joints let go after so many heat/cool cycles and a good knock jiggles stuff enough to make it work. I hit an old TV hard enough to detach the shadow mask one time, and that meant an immediate shopping trip for a new TV. Sears TVs, you won’t really be missed.
