when I was a boy tv reception sometimes would improve if I reversed the plug. this works on radio too. Todaymost appliances and plugs are polarized to prevent the mismatch of wires. but wrong connections can cause a degrarded signal. From an Electrician

I retired a few year ago from a tv repair store. One of my most memorable puzzles was a tv that would work in my shop but not at the customers home. After two or three sessions at my store, the customer took the tv home and, on a whim, used a polarity checker on his ac outlet. Sure enough, the wiring was backward, neutral and hot were reversed. He corrected the wiring and it fixed his problem. He was kind enough to tell me about it. To this day, I dont understand how, with bridge circuits, reverse wiring could affect the power supply in the tv.
But it did! Perhaps it could cause problems in computer products too.
