Having problems with your Dell UltraSharp 2407WFP 24" LCD Monitor ?

How do I remove the back cover on a Dell 2407 WFP?

\015 I feel that the backlight is overheating. After the first 20 minutes or so, the screen goes black. The lights are all on. If I turn the monitor off and back on it will immediately go black again. If I let it set for a few minutes, it will stay on for a while, until it heats up again. I am out of warranty and very dissapointed in Dell. Thanks\015

Hi, I can't offer you a fix for your overheat problem, but here's how to get into the 2407WFP!
\015\012
\015\012Place the monitor face down on the bench. Remove the four screws from the back.
\015\012Turn the monitor over and lay on its back. With your fingertips gently ease the front bezel from the glass, starting far away from the buttons and not putting too much pressure on the glass. It comes away with a series of clicks.
\015\012I managed this easily, but if your fingers aren't strong enough you could use a lever (you MUST spread the load on the glass so as not to break it, and avoid doing too much damage to the plastic of the bezel!)
\015\012Work your way all the way round snapping the bezel from the front, but don't completely remove it as this will strain the ribbon cable from the buttons.
\015\012Lift the screen and rest it on one edge, and you will find the back starts to come free from the insides.
\015\012Carefully lay it flat on its bezel again and lift the main rear casing away.
\015\012
\015\012You are in! To get at all the boards:
\015\012Undo the 8 gold-coloured screws from around the edge of the central metal cover (not the four which hold the VESA-mount in place) and all three covers can then be removed to expose the backlight inverter board, power supply board (very similar to the one in the 2405FPW, see related articles if the PSU is your problem), main controller, and USBhub/card reader PCB.
\015\012
\015\012Hope that helps you - now to find out why it's bust!
