I have the 36 inch CRT HD(KV36XBR800) Sony Wega set and have had a problem in the upper left hand corner, discoloration problem. So the Tweeter tech came to my house with his De-gaussing tool (sp?) He ran it a few times with no sucess and thought right away that the picture tube needed to be replaced. As he tried to set up the time to pick my TV up, his boss said that all it needed was little magnets. (The tech had no idea what his boss was talking about) Anyways, after the Tweeter tech ordered the magnets and left, I noticed that my T.V. image was no longer symmetrical. It seems slightly distorted near the bottom. ( I hear this is called Bowing or pin cushion) Can running that Tech wand too much screw up my TV? Personally I don't think the Tweeter guy was certified to be doing what he was doing. Just trying to gather some information before I talk to Tweeter tomorrow.
