Power button for monitor is broken


leighkavo, it would be easier and less of a hassle to purchase a new monitor than trying to replace the power button. You can do so, by going onto Ebay and seeing if there are parts for your particular model. Then you'll have to break open the casing on the monitor and replace the circuit board where the power button is housed.

What type of Monitor do you have? Here is a Dell example of replacing a Monitor Power Button. http://www.youtube.com/watch?v=RXAQxwCTuuI

Screen bleeds into white after coming out of sleep mode. Turn on an off a couple of times and screen is fine. Is it my video card or is my monitor dying?mag FP-2226AFW 22"


guest, FP2226AFW may have internal "switch-mode-power-supply" problem. Swollen electrolytic filter capacitors or "thermally fractured" component leads to printed circuit board solder joints that will need to be "reflowed" to restore unit to normal operation. Prove that problem is monitor by swapping-in a known-good monitor to your pc first!!! If pc is ok, then 2226AFW unit will need "tear-down" and Inspection" of it's "switch-mode-power-supply/cold-cathode-fluorescent-lamp INVERTER power supply printed circuit board. Do some reading in my fixya profile and those of other CCFL back-lit lcd monitor tech's and you may just find a solution. All CCFL back-lit lcd monitors of the same basic design and functional operation. 12fixlouie

Cannot adjust screed size with control buttons on FP988D monitor. The only one that seems to work is the on off.


Hi there!
It's seems your control buttons panel are busted. If you can access LCD control panel, reset to defaut setting. That might solve the problems... If not, you need a new Board.

The power switch does not switch (no click)


Unplug the monitor from the power
Unplug the monitor from the computer
Plug the monitor back in.
Try turning it on.

DOES IT SAY "NO SOUCRE DETECTED" or soemthing like that???

if it DOESN'T it means there is something wrong with the computer.

if it DOES:

plug it back on to the computer, turn the computer power off.
Press and hold the power button on the computer for about 15 seconds.
Plug the computer back on.
Try turning the computer on.
if it's not turning on again there a problem either with your monitor cable, or the plug, or the video card plug. It is unlikely that your video card is broken if you hear no wired series of short and long beeps when you try turning the computer on.
Good luck.

Monitor does not turn on


It would be good to know what make and model of monitor you have, this info can usually be found on the back on a label. It sounds to me as if the standby circuit has an issue. if you feel up to the job you could dissasemble it and take a look at the internal fuse, the actual switch mechanism itself and any capacitors on the board for the power circuitry. Pictures would allow me to help you more

AOC 17" Flat Monitor (silver)


Hello all.I had 2 AOC monitors with this kind of problem also and figured out the problem with this kind of monitor. All you have to do is to unscrew the monitor and get the control control switch buttons on its circuit board. There are four switch button that control the monitor with four pins each that attaches to the circuit board of AOC, another option is to replace the switch button with a brand new  control switch button which can be bought to your local electronic shop. Now i had no problem with my AOC monitor because i literally removed those switch control buttons from its circuit board.

Solution: Replace cap. Radio Shack sells a 1000uF, 35V cap for $2. This will work.

Why did the cap go bad? The cap is too close to a heat sink and over heated.

What does this cap do? This cap sends a signal to an IC which keeps the monitor 'on' after the power switch is pushed. When the cap is weak, AC ripple voltage is applied to the IC and it sends a signal to shut the monitor off.

Opening the Monitor: These monitors are difficult to open.

The two plastic pieces snap together and must be pried apart with a flat screw driver.

After removing the stand, you need to insert a flat screw driver at the bottom of the screen where two slots are located. Then work the screw driver around until the two plastic pieces are separated.

Remove the cover plate and unscrew the push button circuit board.

Unplug the monitor cords from the driver board and remove the screen.

Unscrew the mounting screws from the power supply board and remove.

You will need to pinch the plastic support in the middle of the board to remove.

Cap Replacement:

Cap is located near a copper heat sink and the value will be on the side of the cap. It will be bulged up on the top. You will see burn marks on the board surrounding the cap. Unsolder the cap.

Install the new cap and solder. Make sure you connect + of the cap to + marked on the board.

Be careful not to solder across joints.

Keep leads long so you can bend the cap as far away from the heat sink as possible.

Reassemble monitor and turn on.

This should solve the problem.

How to fix a dell monitor dimension 2400 power button broken


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.
