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 have the same problem. Anyone knows how to fix it?
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.
I ended up calling Tech Support yesterday, and after trying a few troubleshooting ideas which didn't work, the man I spoke with said that he would put in an order to replace my monitor.
But now I'm worried, if you think it's a tower problem, maybe I should have asked for a tower replacement, especially if you have a flat screen (I don't).
I guess once the new monitor arrives, I'll see what happens.
Well I guess I have to do the same thing cause if it aint the Tower problem then I'm going to have to send the monitor back. I switched cables cause mine came with a white (digital) Cable and a blue (anolog) cable, it seems to be working so far with the blue cable but the white (digital) cable looks so much better and I'm not gonna settle for anolog when the dag monitor alone is costing me $800 dollars. The reason I'm getting the tower switch is cause the last person I talked to (customer support) told me it was my video card. But I dont think he really knew.
I don't know if this will help, but it made me feel better: I called Dell Tech Support and they sent me out a new monitor (got it in less than 24 hours from when I made the call, too!) and I set it up today. While I was unplugging the old monitor, after it was unplugged from the tower, but before I unplugged the power, it did the blacking out thing. So I think it's *not* tower related.
The new monitor is working great so far, but granted, it's only been plugged in for about half an hour.
I had the same problem with my FP1800. It would occur ONLY when using the DVI cable. It was fairly random but seemed to occur mostly when I would minimize a window on the screen. The monitor would blank out for a 1/1.5 seconds or so and then come back on. the LED on the front never changed from green.
I had contacted Dell about this problem the day it happened (which was the day I got the monitor). They sent out a replacement monitor and it did the same thing. This was using a different DVI cable as well. So at this point we've ruled out a monitor issue as well as a cable issue. Also note: this ONLY occurred when using the DVI port on the monitor, VGA worked (and continutes to work) perfectly fine.
I've concluded that the problem lies with the DVI out on my Radeon 7500 card. This is 3rd party card I installed that is out of warranty so no replacement for me.
