Weird CRT Problem

I've got a Dell 1130 CRT (it's got a Sony Tube), 21". I've had it for 5+ years. Anyway, I've been planning on upgrading when it dies to a 27 or above LCD. After returning from the 4th of July I turned it on and it worked for a few minutes and then I heard a sharp popping sound and the screen kind of snapped in the middle of the display (the signal, not the actual screen). It then returned to normal and looked fine. It did this about 4 times over about 10 minutes and then was fine for many hours. The next day it happened again once or twice.

Is it dying? Do I need to be looking at a new LCD now? I was a little afraid it was going to blow up in my face! I wish I knew what was causing this.
 
I have a Sony FW900 that does that if I don't leave it on 24/7. It will get blurry first, then pop, then get blurry again, sometimes for a few minutes, the POW, razor sharp again. So I never turn it off, it seems to just anger it. :D

Dont worry it cant explode to your face;) , but maybe is dying or are only dying some components, i have monitor that has
the same problem and there was only damaged condenser, i think it can be repaired.:D
 
OP there are several discussions with other people having the same problem in the giant FW900 sticky thread. Pretty sure most of those discussions are located in the last 15 pages or so (post # 2409 for example). There were some odd solutions but a couple of people managed to lessen or eliminate the problem entirely. The solution usually involved leaving the monitor on for a long time (days that is), with a screen saver and no sleep mode.

That's interesting because that's the way I normally run this monitor. Thanks for the info/help everyone!

Days? Try.. over a year.. I only turned this FW900 off when I needed to plug in the Windas cable once. :p

It doesn't solve the problem, though, it just prevents the conditions that usually cause it, which is something that seems to occur during warmup. About once every 3 months or so it will just do it out of the blue no matter what though.

I've had this happen about 3 times on my FW900. Didn't casue any damage to the screen, no issues, other than scaring the S**T outta ya. Also had this happen once on a old 20" Sony CRT and it kept working for days afterwards. My best guess, it must be some static electricity jumping across some dusty components, my best guess, I'm no service tech so who knows...

LOLz... I know what you mean about it scaring the shit out of you. A friend of mine that works in the industry thinks it has to do with the high voltage section of the monitor (he said something about the flyback transformer and such).
 
wow i'm happy to say that i havent had this kind of problem with my HP :D
 
What you described is a fairly common problem with the last generation Sony tubes -- lots of people have complained about the same thing. I don't think it means that your monitor is in imminent danger of dying, but it is definitely getting there. My Sony G420 did the same thing a few times about two years before I got rid of it, and then never again.
