Question about Dell Dimension 2400 PC Desktop
When I turn on & off the power button it moves inside the monitor and now it won't even turn off. The power button needs to be fixed. Any suggestions on how I can do this myself will be appreciated. Thanks, Andy
The last guest left us hanging with, "easy fix" so, I ventured ahead to see what I could see by opening up my lcd, which was a puzzle in itself. After UNPLUGGING the monitor and removing the stand and the 4 obvious screws in the back, turn the monitor onto its back and placing your palms against one side of the monitor, and using your FINGER TIPS, gently pull back the plastic lip away from the LCD screen. Move along the lip, doing this a little bit at a time. You'll hear and feel it snap loose. Repeat on the remaining three sides. It may take a few rotations to free all the sides, doing a little at a time, so as not to put undo stress on the plastic that is not yet loose. The bottom lip from behind which lies the offending "on/off" button will not move as freely as the other sides because of the ribbon cord that attaches the circuit panel to the main body. So STOP pulling when you feel it become taught and carefully turn the monitor onto its face to complete the face's removal. Undo the cloth tape that secures the ribbon cable to the monitor. This will give you the necessary slack you need to do your dirty work. BTW, we're not disconnecting the ribbon cable from its connections- that would be bad - just remove that haphazardly placed piece of tape used to keep the thing snug and save it for when you're ready to close it back up. OKAY! There a four tiny screws that affix the green circuit board. You'll need a thin, jewelers type phillips head or a one from a synthe-sized tool set to remove these. Now, if your issue is like mine, you'll see when you again carefully remove the circuit board, that the on/off button has cracked off of the piece that holds it. This is why the button remained stuck in one positon when it was depressed. Re-align it so that it is uniform to the other buttons and place a few small strips of cut electrical tape to hold it in place to the end where it broke off. Crazy glue or the like won't give the button the flexability it needs and will probably just crack again. What the tape (I layered 3 strips) will do, once the circuit board is scewed back, is allow the button to return to position after it's pushed. I just did this and so far, after a dozen on/offs it's still working. Good luck. Go have a beer.

Spin the power button so the line is at the top straight up and down. I was ready to disassemble my monitor and saw this tip on another site. Works like a charm. Stupid Dell.

Hi, my best advice is dont try it. Monitors are not easy to access and expensive to have repaired. A simple fix is to plug it direct into a switchable power outlet and just switch it on/off from there. Regards mistyman

If your on and off button does not work just take off the trim. You will find that the plastic button just broke off. Take the button out, put the trim back on with out the button and now you just need a pin to push the on buttom. That's it.

First of all if your monitor is stuck in the on position - you are lucky- do nothing- get a power strip. For those stuck in the off position, The Delli Lama does have the best solution - I just did it but wanted to amend with a couple of tips. Pulling the plastic frame up is not easy . There is metal around the screen and I had to work a small flat screw driver between the metal frame and the plastic to get the first amount of separation ( with a pop) - then worked my way around- just be careful not to touch the glass with the tool. Following delli's instructions I got the circuit board off and yes one of the three tabs on the button was broken. The button tabs are in the same place as the wheels of a tricycle. My front wheel tab was broken. Unfortunately that tab actually is what touches the board to turn it on. I then simply performed the buttonectomy described in #6 and removed it. Important - the actual power button on the circuit board is located just to the left of the power button hole, so sticking the eraser end of a pencil in only touched the light . The power button has a tab on the left which pushes the actual button-my tab was gone. I suggest plugging in the monitor while the board is accessible (don't touch anything) and pushing the button on the board to power it up - if it works pull out the power plug and re- assemble . Then when it is plugged in it should come on. Just use a power strip to turn off and on. I don't see how the original button can be made to work again and I also don't see any easy way to get to the real switch after re- assembly because it is hidden just to the left of the power button hole. Don't be afraid to try this , it did not take long and the only special tool is a small screw driver.

My problem was the power button broke in the off position. The best solution posted by Dellillama worked for me,with a slight modification. Rather than replace the power button, I simply left it out and used a pencil, eraser side, to push the real power button (which is on a small circuit board inside the plastic panel) on once I powered up the computer. And I leave it on rather than turn it on and off each time I use the computer. Rather than a gaping, green-lighted hole where the power button used to be, I covered it with black electrical tape...sort of a power button-ectomy.
The problem was that the power button was connected to the computer by three very thin plastic posts, and it had broken off of them. To say this is cheap construction is an understatement. The jokers at the technical help desk told me my only solution was to buy a new monitor. PS - My monitor was a 17 inch Dell 1704 FPTt.

across this post after fixing mine. I did the same as Delli Liama.
Except I put a small dab of silicone sealant on the hinge part of the button. Then put a small piece of thin plastic over it so if I had to take it apart again the silicone would not stick to the PC board. Remember not to cover the whole button or the light will not work. This was about eight months ago and all is well

My button somehow got stuck as well. I picked the plastic part of a button out with this cuticle nail picker thing I had in my drawer (yea for chicks fixing computer problems!) and then I simply used a push pin to return on my screen. Please note that the on off switch to the motherboard is actually a little to the left of the plastic button it presents...it is like Dell made it for safe keeping. I will use the suggestion to get a power strip to turn it off and on, yea for saving money.

Hey all. I found a very quick, if not permanent solution. Had the same problem and of course in the off position. I noticed that the icon on the button itself was not pointing straight up as it always did. I also noticed it didn't make the clicky sound when pushed. So I grabbed a little piece of paper tape and and stuck it to just the button and rotated the button so that it was pointing straight up and bamm, monitor started right up! Now I get a power strip ;)

I had same problem with my 2 Dell monitors and from then on, I only buy Samsungs or View Sonic

I have a flat screen Dell that I got from a friend. The power switch wouldn't work. I took it apart, which is easy, and found that the chip for the monitor controls, plus the on/off switch was broken off right at the end where the on switch is. Easy fix

There is a small, long circuit board held by three screws, under the switch push-buttons. The actual switches are metal spring domes that are depressed by the plastic pushbuttons to make contact under the dome. These metallic domes can be pressed by about anything, even a fingernail, to make contact. The power push button is bigger than the others and has the green LED under it to indicate power-on. This is the problem. The other, smaller switches have their metallic dome directly below them. But, the metallic dome under the power button is offset to the left (because the power LED is directly under the button) and the power button dome is pushed by an unfortunately thin tab stick off to the left of the power button. This fatigues and fails (the tab breaks) long before the other buttons might fail.
The fix we settled on was: taking off the plastic rim around the front of the monitor (it holds the plastic push-buttons) , prying it off and inch or so at a time. Then, unscrewing the small circuit board and drilling a hole next to the power push-button, directly over it's metallic spring dome switch. We then put in a small nylon screw, with the end inside the plastic, directly over the targeted metal dome. We screwed a nylon nut on the shank of the screw which sticks out of the monitor a little ways and cut the screw off beyond the nut. This gives a little somewhat floppy, plastic pushbutton for power, and the old power push button (still in place) still lights up when power is on.

Generally, this method applies to the Dell W1900 LCD/TV monitor. Rather than some monitors or laptop screens which give access by prying off the front bezels or trim, the Dell W1900 gives access by removing the large black back cover. Here's how I did it:
Unplug. Remove the rather heavy stand. Remove six screws around the outside edge of the back cover. Remove four screws where the stand was attached on the back. Then gently pry off the rear cover with a flat head screw driver or wedge. Pry around the entire circumference a little at a time to gently unsnap and remove the back cover.
This gives access to the power button (and all the buttons for that matter). You should be able to see what is causing the mechanical problem- for me ...a broken plastic "wing" of the two rather flimsy wings that rebound the pushbutton power button.
Then pick the best solution:
1. fashion a new pushpin solution.
2. leave in "on" position and use remote control or a external on/off power strip to power monitor on/off.
3. apply pressure to the correct part of the power button..for me just one side of the flimsy plastic "rebounder" was broken. So I magic marked where to push for the best on/off direct push. (for me this was the top). This probably won't work if several people use the monitor.
4. Something better.

Answer to some of problems above 2 yr old Dell monitor just went out. We guessed the switch was bad after reading the above posts. I figured I was being green by turning off the monitor each time. Do not do this!! We used hints above and we 'fixed' it for now. Hubbie got the face plate off the front. Takes some doing. Un plug and disconnect monitor of course. Lay flat on it's back. using a thin screwdriver..pry off the front lip..working around the edge very carefully. But hey, we figured we had nothing to lose. be careful as the little circuit pad is attached. you have to carefully unscrew the circuit pad..my smaller hands worked here. We tried the tape thing..but it did not work..so I used a pencil eraser and it came right on. then more difficult...The hardest part...using the tiny screws to put the circuit pad back on. Needless to say..we are leaving it in the on position. We have a sticky over it to remind us.
So we had a $200+ monitor with less than 2 cents worth of plastic on the switch. It was so flimsy..paper thin. It is a wonder it worked at all.
So for your info...latest from Dell. At the time we bought.. monitor had only a 1 yr warranty...since we bought with a Computer. If you buy alone you have 3 yr warranty. Now I notice Dell is giving 2 Yr warranty on all? Ok..makes no sense.

There is a small tab on the side of the power button which makes contact with the switch and probably has broken off, if you push any of the other buttons on the monitor and they snap back they are working properly, I do not know if Dell offers a replacement trim for your monitor or not (which has the buttons made into it), I have the same problem and trying to find out if they even offer a replacement. You can remove the trim by removing the 4 screws from behind the stand and then carefully removing the trim.

My 24" Dell monitor won't turn on .. just happened today. Paid a lot of money for this monitor and it looks like a 10 cent on/off button is the problem...and I don't feel comfortable opening it as described below. I'll call Dell about it and see what they say, but if they say buy a new one just for a broken button, you can bet I'll buy a different brand. Dell is going down and no wonder.

I have a Dell Dimension 2400 computer. I purchased it used. The desktop on the monitor is blurry. How can you clear it up?

To run dual monitors will require you to install a PCI video card.

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.
