Mass Monitor Murder

This is really quite bizarre. Here's how things were a few weeks ago. In one room, the "office," my family had two regular desktops, and a laptop connected to a regular CRT monitor. My parent's PC had a Gateway EV910 monitor that was about 4.5 years old, I had a NEC/Mitsubishi Diamond Pro 930SB I purchased new in October 2004, and the laptop is connected to a Dell P793 monitor that's about 3.5 years old. All three monitors have been in this room for about as long as they have been operating in our household.

About 2 weeks ago, my mom complained to me about her monitor looking darker than usual, and asked to see if I could do anything about it. I made some adjustments to the settings which helped a little, but I could do little else. Not long after, it eventually died (Well, I'm assuming it's dead. We haven't tested it since.), and now we have an LCD connected to this PC. I didn't think much of it at the time, I know monitors don't last forever.

Then, probably about a few days to a week ago, the same thing happened to the monitor connected to the laptop. It suddenly became very dark one day, and simply seemed to die. Now we're using the laptop's own screen. However, I haven't tested this monitor either to see if it may have made a recovery, of sorts. Now I thought this was weird, two monitors in such a short time, neither of them being particularly old either.

Finally, last night, I noticed my monitor was suddenly much darker. My desktop was once a bright navy blue, but now looked nearly black. Game levels that were formerly just "dark" were now altogether unplayable pretty much. I increased the brightness a bit which helped, and when I went to bed, everything looked to be ok. Then, when I woke up this morning, I found my monitor with no picture on the screen and the power button blinking. I tried turning it off and on, but it didn't do anything. I didn't have time to do much else then until I came back home from school. Same thing was still there, everything was ok except I had no picture. I turned the monitor off for a little while, then tried turning it back on. I had an exceptionally dark desktop for a few minutes, but then it disappeared again. I proceeded to try everything I could think of, I checked all the connections, I tried a different powerstrip, I restarted the PC + Monitor. I haven't gotten the monitor to do anything except display a dark picture for a very short period of time and then 'die' again.

So here I am now. I am, to say the least, quite puzzled. I'm going to investigate the warranty on my NEC/Mitsubishi monitor, since it's only about a year and a half into the 3 year warranty it has, but I think the other two are quite past theirs.

More than anything, I'm really just sort of concerned as to what may have caused this. Has anyone ever experienced anything like this? Is there anything I should do to try and recover the monitors? Could it happen to another monitor if/when we replace them? Or is it just one big, miserable coincidence?

If there's any other information that would help, I'd be glad to provide it. Thanks for your advice :)

I've had that happen. One working monitor suddenly doesn't work, I had the same problem with the picture darkening.

Unlucky, could it be some sort of interference in the room? Are all the monitors that went dead crts?

It might be a good idea to buy a voltmeter and check the line. It's possible that the outside line may have experienced some fluctuations (bad transformer, lightning surge), or it could be the house's internal wiring. Or it could all be a coincidence, but the timing and similar nature of their deaths makes that highly unlikely. I've never heard of electromagnetic interference actually killing monitors, but like anything else, if powerful enough, it could do it I suppose.

Thanks for the input, everyone. I'll look into getting ahold of a voltmeter to see if anything is out of the ordinary.

And yes, all the monitors that died were CRTs.

Just a bit more info, after letting my monitor sit without power for a few hours, and then making one last attempt, I no longer even got an image.

yea once is random. twice if fishy. three times, you got something goin on here. check power, check interferences, check for radiation. it could be anything. i dunno. ;P

Are the Monitors and PC on a UPS ?

If not, then I'd seriously suspect you're getting some kind of power issues on your lines - either low voltage, spikes, or a lot of noise.

I'd definitely get a UPS before hooking up a new Monitor, otherwise you may be looking at some more casualties. A UPS will not only provide
some backup time, but more importantly it will filter the power going to your components. Depending on the UPS model, it may also identify
what type(s) of problem (if any) you're having on your lines.

check out for speakers nearby.... magnets for a LONG time can cause damage, even if not noticable degaussing needed
