I have a 18 year old Toshiba (don't know it's history as it's at least 2nd hand TV for me), that I noticed has a permanent colored spot at the bottom left corner, similar to what happens when you pass a powerful magnet by the tube. But there are no magnets (the speakers are far enough away) near the TV. Under the TV is a couple pieces of electronic like a Wii and a reciever and DVD player, but nothing that's not supposed to be by a TV. Any idea what this my be and if there is a solution to this?
The degaussing circuit has failed. Usually this circuit kicks in either when you turn the set on or off. This clears up any magnetic interference on the CRT. Toshiba sets usually have a 3 legged thermistor that controls this. I suspect that this part is defective. The parts cost for this is under $10. Check around for a servicer that can replace it for you.
