Let's just pretend this didn't happen and not ask any questions.... Walk away slowly...

I tried that once. An intermittent contact problem in my TV set was fixed by putting pressure on one of the PCB boards. It seemed like that was the proper fix. I called it fixed and walked away.

Eventually, over time, I would have to change the amount and direction of pressure on the PCB board to get it to work properly again. Then eventually no amount of pressure was enough. Finally I got fed up and disassembled the innards completely to remove the main motherboard, found the bad solder joints, resoldered them, and the set's been golden ever since.
