Post by thread:Degaussing TV sets

A few notes on degaussing a TV set or monitor.... DO NOT USE A TAPE BULK ERASER!!!!!!!!! The magnetism of these is so strong, unless you are VERY careful and know exactly what you are doing, you WILL suck the mask of the CRT out of place, making the rainbows PERMANENT. I'll be new CRT time. I know, some of you have done it with no ill effects, but you were VERY lucky. Think of this, the bulker is strong enough to lift a VHS tape, it will have no problem distorting an approximately 22 ga piece of mesh. BUY A DEGAUSSING COIL These can be had for as little as 30 dollars US, there is a vendor here on the web somewhere. If you cannot get a degaussing coil, TRY the one in the TV, turn the TV on and off at approximately 30sec intervals. The degausser has a timer which keeps it from heating up. If all else fails, call your friendly TV repairman, he can make short work of it and if you sweet talk him, he may even do it for free.

The degausser has a >timer which keeps it from heating up. It's no good only leaving it off for 30 secs, TV's don't have a timer, they use a device called a 'posistor' to feed the deguass coils. This consists of two thermistors, a negative coefficient one across the coils, and a positive coefficient one feeding the coils. Some modern TV's now use a two terminal 'posistor', this is just a positive coefficient thermistor and is used to feed the coils. Anyway, back to the story, these posistors get seriously hot and take a LONG! time to cool down, they need to be fully cold to give the maximum deguass energy - at 30 secs you wouldn't get any, I would suggest at least half an hour, and possibly more!. -- Nigel. /--------------------------------------------------------------\ | Nigel Goodwin | Internet : nigelgKILLspamlpilsley.demon.co.uk | | Lower Pilsley | Web Page : http://www.lpilsley.demon.co.uk | | Chesterfield | Official site for Shin Ki Ju Jitsu | | England | | \--------------------------------------------------------------/
