Hi, From your description/post, it would seem that something is overheating in your monitor. It is possible to be a cold solder joint or a component starting to fail. Since this involves component level repair, use of a VOM and a soldering iron, it sort of limits a do-it-yourself repair not unless you are comfortable working in such an environment and with such tools and equipment. A sure sign of cold solder though is if when it is jarred it turns itself on. The "growing darker" possibly indicates backlight fading. You may need the services of a qualified professional to have this repaired. Good luck and kind regards. Pls post again should you need further information.

LC26AD5E screen goes black after few moments and sometimes almost immediately. Does not switch off onto stanby using remove - have to use top button.
I'd suspect EITHER the Powerboard capacitors failing, opening the case (after switching it off and leaving it for 24 hours to drain charge) and looking at the capacitors to see if any are blown or bulging will confirm this, as will blackening on the board.

Or, the video board is failing. Power getting to board but not making the circuit to light the display, or an associated fault.

When I switch on the computer and monitor, the monitor comes on then goes off straight away, so I have to switch it on and off several times before it will stay on. What could be the problem.
99% of LCD monitors and TV failure are due to bad DC filter caps as you can see in my albums.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

The display driver on my Inspiron 530 keeps failing, the screen freezes/glitches or goes black, then starts functioning again about 5-10seconds afterwards. This can happen several times in a few hours,...
This could be a problem with your monitor, your vga cable or your graphics card, or a combination of those so you need to eliminate them. It would be useful to test your monitor on another machine if possible to eliminate the monitor and cable. Generally Dell also have on their CD's a diagnostics utility that you can boot into to test for example the graphics card. By a process of elimination, you will pin point where the problem is. You could also double check your electrics..!!

Screen not appearing straight away
It could be your LCD backlight giving you problems till it warms up. Turn you computer on and while the monitor is displaying black and the power LED is green shine a flashlight in the lower left hand corner of your screen. Look for the ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. A 15" LCD monitor is probably not an economically repairable problem unless you have access to really cheap parts and have the skills and tools to do the repair yourself.

Dimension of image change when displaying clear or dark image
Same problem Picked up this monitor about half a year ago, a Viewsonic A91f+, and have been having some issues for a while now concerning what appears to be shifting in the monitor image, but that is about the best I can describe it as. It is most noticable when a large dark area meets a light area, like text or window edges. This "shifting" only occurs on the right side of objects and seems to show most often after I switch resolutions more than a few times, usualy due to gaming. Ive also noticed it happening from running random programs that dont require resolution changing/flickers but this happens FAR less often. -photograph of the effect- As you can see, its pretty subtle on a darker background, but Ive had no luck carturing it on a light one. Anyone have any idea as to what is occuring on this monitor and how it could possibly be fixed? Possibly an issue with magnets? For a while, I did have a small headset hanging off the the monitor on the side that the images "shift" towards, but even taking those off and away havent fixed it. Currently the only fix I have found for this is to shut my monitor off for 5-30 minutes, depending on how bad the "shifting" is when I find a time break long enough to fix it.
