Power button for monitor is broken - Dell Dimension 2400 PC Desktop

Sounds like your button may be broken internally.

Try unplugging the power from the monitor and plugging the power back and turning the monitor on.

Does the menu pop up on its own?

If it does then your button is broken internally.

It may have broken actuator or the arm for the button is now broken, it is very poor design, I cannot locate anyone that sell this assembly yet. You may be out of luck, what I have done is to remove the button and use paper clip to actuate the switch.

THe push button (the button is used to push the switch shaft) is held in place with a plastic finger, it is broken off right now, that is why it dropped back in hole. This is how most of the front panel push buttons are made on most monitors, very cheaply made and design. If the finger is broken in the middle, some time I can fix it by using Silicone RTV to glue it down because the Silicone is flexible. You can try that out.

I would go ahead and get a new monitor. It sounds to me as if the button is broken were it connects on the inside

broken power switch... .. the "friend" broke the power switch by pressing too hard or as luck had it the switch is broken..

recommend leaving the monitor unplugged for 4 hours

open the case of the monitor up and pull the small circuit board for the "buttons" out and get a replacement board... google the part number exactly as spelled out on the little button board

First you need to troubleshoot a little. You should first try another power cable for the monitor, if that doesn't help, you might be able to open up the monitor case and check wether the button is broken. If the button is broken, you're going to have to improvise a new one, since new buttons aren't really being sold. If that isn't the case, or if you can't open up the monitor, take it to computer shop, these things are easier to fix if you can look at it. I hope this helps, Yannick.

Yes, I think your right, if it is under warranty send it back to Dell for repair, I had the same issue about a year ago.

Hi,

Thanks for responding. Nothing happened when you pressed in the power button and the warranty had expired; Dell was no help so don't bother. I read that there were tab(s) on the plastic power button that had broken off and no longer engaged the power switch. I "solved" my monitor problem by drilling through the plastic case between the power button and the minus button, pulled out the plastic power button and pressed the switch with a flat screwdriver to turn on the monitor. Now I leave the power on all the time and put a piece of black masking tape over the space where the power button was. Not the best solution I'm sure, the hole isn't pretty, but it works. If anyone else wants to try this solution be careful when you drill through the plastic case because the switch you want to engage occupies the space between the buttons, exactly where you are drilling. If you drill through the switch you might as well throw the monitor into the recycle bin. I expected to find an actual button switch and was surprised to find a flat, 2 prong circuit switch instead. Good luck to all.
