I was at my friend's house the other day and noticed that his TV (about a 30 inch wide-screen tube-based HDTV) had a purple spot in the corner. I remembered back to seeing
these instructions for making and using a homeade degaussing coil and decided I would make one to cure his TV.
Should I worry at all about messing his TV up, though? I've never done this and won't even attempt it if I might possibly make the problem worse. Is there any reason an HDTV would react any differently to a degaussing coil than a standard def TV? What about a widescreen?
Essentially do I have anything to worry about or can I just make the thing and go fix his TV?
Oh yeah...and can I just use a regular arcade pushbutton or do I need something that is made for a lot more electricity to be flowing through it?
Additionally, does anyone have an idea of what wattage lightbulb I should use?
thanks
