white horizontal lines appearing on Monitor screen

[MrEd]

UPDATE:

ok well the lines have been gradually getting worse, so i phoned up the monitors dept of NEC UK, they said they would dispatch a new one and collect mine next week sometime. have to see how this works out.



monitor: Mitsubishi diamond pro930sb 19"

hi,
just in the last day or two i have noticed white [actaully more a transparent colour than anything] horizontal line randomly appearing on the screen. they are quite thin - 1-2mm, some stay static while others might move up and down the screen. there are no other effects from it, except its distacting.

any advice as to why this is the problem and how to solve it? i have had it a year+ with no problems.

unless its EMFs, as i do have 5.1 speakers around the desk, and a big desk lamp, but why would EMF effects only show up now?.

thanks

ok well i moved the monitor down to my room and placed it facing North-South, as oppsed to East - West as it is on my desk. I left it their for about 12hrs.

i removed the speakers from the desk (the bass unit is their but disconnected from the mains) then put the monitor back on my desk and connected it up.

10 minutes later the transparent line were back .
