Monitor is blacking out.

Evil Weevil

Hello everyone.

I've had this monitor since December of '08. http://www.newegg.com/Product/Product.aspx?Item=N82E16824176077

Yesterday after letting it go into sleep mode for around 10 minutes as I was cleaning up, I returned and the image would come on for a second, and then the sreen goes black in definately. I power the monitor on and off and it does the same thing - image is seen for a split moment and then goes black.

I've restarted the PC, unplugged and replugged the monitor cords.

What I DO seem to notice is that if I leave it off for a while and then turn it back on, like an hour or so, it seems to go on longer, but I notice the screen image actually dims and then goes black shortly after.

I'm going to see if it's a monitor problem for sure by plugging in an older monitor, but is there anything I can do short of taking it into a Best Buy for repair? Leave it off during the night, see how long i can have it on when I return from classes?

Edit: Oh forgot, when the screen is black the power is still clearly ON.

I have a monitor that does this as well. From what I have read, it is a blown capacitor. I was unable to open my monitor and tear it apart to look, so I am writing it off as dead. If anyone else has more insight into this problem, it would be much appreciated.

I googled up "blown capacitor on monitor" and noticed that someone recommended turning down the brightness on the monitor. I'm going to try this at home and post my results as soon as I can.

Yeah, definitely sounds like a capacitor issue. My previous monitor died in the same way (would work for an hour, got less and less over a week), was a pain shopping for a new one on-line whilst only being able to see what I was doing in five-second increments. Three hours later it stopped working completely. :P

Edit: Turning down the brightness will only give you a little extra time before it finally goes kaput.

If you have a bad power supply, bridge rectifier or bad capacitors, then it might run until it heats enough to fail. You can replace these parts if you are handy with a soldering iron and can match the parts. Don't buy cheap radio shack capacitors, you will probably need to order from capking or arrow.

Old CRTs had some big capacitors and a flyback transformer. Those things stored a bit and could electrocute you.

Just posting to say that turning down the brightness did zilch for me.

I think I tried that too and I didn't have much luck either. Acer also apparently seals their monitors with magical adhesive. I have wrote it off at this point.
