i had a client come to me today, who had a son who loves to play with magnets. She also has a CRT Apple Display (the see-thru clear graphite one) which has a distorted, multi-colored splotch on the screen, where her son "Supposed (which the son will not admit to doing)" put a magnet up to the screen. Now, i know NOTHING about the whole CRT Technical function works (other than the basic), but, I am guessing that this lady's CRT Display is pretty much hosed. Is there any hope to revitalize this screen?

What can I do, oh applefritter gurus?

TV repair shop

and you call yourself a geek... ...

Any good TV repair shop will hae a degaussing tool. That shouldd solve the problem. Also, tell her to smack that kid around if he comes near that CRT with a magnet again Tongue (seriousily, she needs to educate her kid: magnet + screen = BAD!)

I had a telephone receiver held up to one of the old 15" Apple monitors, which left a big blotch.
The monitor was left unplugged for 24 hours, then when it was put back on, the monitor's own degaussing at power-on cleared it up.

The sci.electronics.repair monitor repair faq recommends "on for a minute, off for at least 20 minutes, on for a minute" to make use of the built-in degauss coil.

If that doesn't work, then a repairman's degaussing tool is the way to go.

ok, thanks

but i think this might need a tv repair shop, as this monitor has been like this for a month, in both the on and off stage. So i don't think the built-in degausing is going to do that. I will refer her to the local tv repair shop.

There is always the chance that the built-in deguass is shot too. Does it make a twang or other "large" sound when it's turned on? I'm not familiar with those monitors, but some can be deguassed through an OSD menu or a deguass button on the back.

Jon, if it is as band as he says it is, the buit in degauss will do absolutily diddily. If it's that bad you need a professional with a good degaussing tool.
