electron gun(s) and magnetic fields
I have a 54" RCA rear projection. I had a new hardwood floor installed
with an electric heating grid underneath. The grid consists of heavy screen mesh, similar to window screen but 2-3 times heavier wire, laid in one continuous circuit back and forth across the room. There is a high voltage, low amperage current running through it. Here's the problem - when the heater is on, the guns in my tv misalign, looks like 3-d image viewed without the correct glasses. Soon as I turn off the heat, the tv returns to normal. How can I shield the tv from the floor induced field? Faraday cage? (I don't really want to view thru wire mesh!) Grounded sheet of steel under the set? Raise the set a foot or two off the floor? Both? Any suggestions, particularly from those who have solved this problem or engineers, would be greatly appreciated! Real E-mail: gpdewitt at earth link dot net (no space in earthlink) |
