....STILL no collapses !!!!
....am pretty sure now that it must have been tracking across dust, there
was some pretty grim black looking powdery dust in there - not excessively
thick, ...very little "household/skin" dust. ...or did I disturb that dry
joint in there, in a beneficial fashion ? !!! :-)

...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

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

Thanx James,
Perhaps tommorrow I'll whip off the cover and take a look around it with
a bright light and a magnifying glass, if I can't spot anything with the
naked eye.
Tiz all so time consuming ...so many other things to do !
regards, Richard

Hello all,
Can anyone help me as to how or where to locate a fault in my NEC FE750
monitor (.25mm dot pitch / flat aperture grille tube). Every few
hours, (it's done it about 5 times now over the past few days), I get
loud "Clunk" sound as if it's just been switched on or off - picture
field collapses to a bright horizontal white/magenta line, (pretty sure
it's not white), field collapse lasts for just a second then "clunk"
again, and Windows desktop appears in the middle of a degauss cycle
then it's fine again for hours.
This NEC monitor was in storage from new along with several others for
years, I've had this one for about a year, tube is like new. Shame to
have chuck it for the sake of a disc capacitor ...if that's all that's
wrong !!
...any pointers, or referral to a good monitor repair technician
appreciated.
regards, Richard
You've probably got a cracked solder joint in there somewhere, perhaps
in the vertical or power supply area. Don't keep using like that or
you'll likely cause further damage.
