I have a monitor MAG LT782s. Backlight works, but there is no video. Where should I look for a problem? Thank you.

HI There,

The easiest way to troubleshoot this one is to borrow another monitor that you know is displaying properly on another computer and connect it. If you're still not getting video then it's almost certain your video card has failed.

Squiggly monitor

Since the image on the projector is OK then the problem definitely lays in you monitor. You might want to turn off any other electrical equipment in your lab, especially any kind of radio transmitter and see if that is affecting your picture. Strong magnets or large power cables can also generate magnetic fields that can adversely affect CRT pictures as well. If that isn?t the problem then it is likely the monitor. It can be fixed; however, this is typically beyond the skills of the average user. Any TV and some computer repair shops can repair a CRT but is it economically feasible? A new 17? CRT can be had for $60 on-line and that has a 1 year warranty. Repairing your old monitor could easily run that or more and usually is only warranted for 90 days. Let us know if you have any other questions and please don?t forget to rate this posting.

Squiggly lines in the center of the monitor

sounds like you have what are called dead pixels. This typically happens in monitors that are about 2+ years old. If you are still within warranty i would contact hp about getting it serviced.
