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: Technology
Many times old tech TVs has (depending on the age of the TV) different hardware that plugged into sockets .
These also generated lots of heat. These changes in temp could cause expansion and contraction that might make some electrical connections inconsistent.
If you gave the individual components a gentle wiggle (as a tech person) they would often make a better connection.
As a non tech person, a shake or impact to the outside of the device could occasionally make things better. Sometimes it made things much worse.
Remember that these were often analog devices rather than digital, and the tolerances for “working” were much more broad.
