After we moved my Panasonic Widescreen TV to a new house it now shows a rainbow like pattern over the whole screen, like if you put a magnet to close to the screen. What can I do to get rid of this?

The tube shadowmask is slightly magnetised. The TV will normally demagnetise itself at switch on. It may require demagnetising manually. A TV repairman has the equipment to do this correctly. Don't be tempted to use a magnet near the screen yourself as it could leave a permanent color error. It may also require the replacement of a small inexpensive part, called a posistor, inside the TV. The TV picks up magnetism from the earths magnetic field. If you have loudspeakers near the TV, this can also cause similar symptoms. As can use of power tools, or proximity of large radiators near the TV.

is your video recorder in a closer proximity than before,it maybe that the amplifier in your video is reacting with the tv,if your vid is under the tv,afix a thin steel plate under the shelf,between them,to isolate,this worked for me some time ago
good luck
