Re: NEC FE750 17" PC occasional field collapse

....I whipped off the back and removed the tin shield, blew it out with my
old faithfull electrolux "cylinder" vacuum cleaner - (where you can connect
the hose on a hole at the top to blow - bought it at a boot sale for £5
several years ago....stripped cleaned it and put a tiny drop of oil on each
motor bearing....marvellous for blowing out PC cases . / PSU's etc.)....the
pallaver to get the board out of the thing is a major time consuming joke,
so I reassembled it, I'm going to throw it away if it plays up and get a LCD
monitor from my favourite vendor http://www.aria.co.uk

BTW ...since blowing it out, I haven't had a single field collapse !!
....tracking or arcing via dust ??

regards, Richard
