Re: Need a rubber hammer
Depends on the problem. I shared a flat with some other students back when I was in college and we had an old CRT TV in the living room.
Occasionally the image would flatten to a single bright line in the middle. Tried cleaning the variable resistors to no avail.
Then I brought in an old-fashioned wooden mallet that I had made in shop class in secondary school. Worked like a charm - we'd just whack the top of the cabinet with it. We kept it on top of the TV, next to the (acoustic!) remote control.
Oh, those were the days!
