I do this because my tv is on a swivel and sits on a cabinet above my entertainment system (The TV is a 27" Sony Flat screen Trinitron). When I swivel it to the direction I am facing it picks up this weird discoloration in the corners from magnetism or something like that. I know this because I asked about it once in a forum like this and was told. I was also told that this is somewhat normal. Is that true?

Therefore, I must unplu the set while it is on and have ot off for a few seconds and replug it in. This does something to reset and basically wipes away the discoloration. But, I swivel my tv constantly and it always happens thus the same process over and over.

Anyone ever come across this and have done similar? And basically, over the life of the TV is this harmful to do? It would seem to me that it would. Please let me know any and all thoughts and if there is something less harmful I can do. Thanks in advance.
