There is NO FIX for this one since repair exceeds the cost of a new monitor. If it was mine and I know that LETHAL and FATAL VOLTAGES are inside the case, I could cut the degaussing wire that runs around the tube. Or unplug it. Eventually that will lead to another problem in which it needs to be dagaussed, but it could give it another month so you can go shopping.
My wife has an NEC CRT monitor. Her PC is running Win98. Yesterday, after her monitor had been on for a while, the degausser started turning on by itself. soon it was doing it over and over again to the point where it was hard to do anything on her PC. (Very annoying). We turned her monitor off for the night and it was working fine today, until it had been on for a few hours. Any suggestions on how to fix this? Thank you in advance for any help with this problem.
