I have a relatively new monitor and computer system (bought May 2003) and in the past few months, the monitor will go completely black for about one second and then come back on randomly throughout the day.
It will do this completely randomly and sometimes will not occur at all for a week or so, but then without warning, will start up again, going black many times throughout the day. The diagnostic lights are all on green normally, and since the screen goes black for only one second, I don't have time to check the tower while the monitor screen is black.
The power light stays solid green with no change when the monitor goes black.
I've checked the cord connecting the monitor to the tower and it's as secure as I can push it in on both ends. A friend recommended that I get a new cord (he said it would the "HD15 (plug) SVGA monitor cable"), but I wasn't able to find anything like that on the Dell website.
Does anybody have any suggestions for what could be causing this problem, and how I can fix it?
Thanks in advance for any help.
I'll try it, but when this first started happening to me, I called Tech Support, and they told me to do that, and maybe for a month or so, I didn't have any problems, but then it started up again.
So if that's a solution, then it's only a temporary one.
