SOURCE: HP deskjet 3054 broken power button

Hp's usually have a micro switch underneath the power button. You probably just broke a support arm or type device. You might be able to super glue the piece back together and make it work. In my experience, this usually works about 40 percent of the time. Usually by pushing to ******* the switch to break the plastic you could have possibly damaged the small micro switch. My best suggestion is take it apart and try the super glue fix first. Good Luck!!

HEWLITT PACKARD MONITOR HP L1950g suddenly gone dark...still powers up

There are several things that might have happened. Blown backlight, broken input port, or blown capacitor/power supply.

If your backlight is broken, you will still be able to faintly see the picture if you shine a flashlight onto the screen. This is a possibility because you're monitor may not notice that the backlight is broken so it will give you the green light.

Try another input if possible. I believe that monitor only has VGA but if it has DVI try the one you haven't been using. I doubt this is the case but it's possible. Also try another PC or different input source and even a different cable if you have one. You want to make sure the monitor is getting a solid signal.

The other possibility is that you have blown a capacitor. They often fail on monitors and TVs. If you are handy with a soldering iron it is an easy fix but you will have to open the monitor to diagnose. Check for specific instructions on how to do this.

Unfortunately, there is no easy fix. The easiest thing to do in this case is replace the monitor but if you have no other choice, just open it up and see if you notice anything wrong. You have nothing to lose since it's already broken and if nothing else, you'll see what's inside and potentially learn from it.

My AOpen 19" LCD Flat Screen Monitor (Model F2915) is like new and works perfectly except for one thing. The push button power switch located on the top of the monitor has broken off and fallen insid

Certainly, if you jumper the connections to see which ones turn the monitor on or off, then you can go to an electrical supply place and get a micro switch and wire it in in place of the power button, or perhaps find a type that is flat that the power button can press. What you need to determine is if it is a push-on, push -off type switch, which always stays on or off depending on position or if it is a momentary interrupt switch where the button pressed momentarily turns it on and then releases and a second press connects the circuit to turn it off. You can do this by testing with your jumper wire, attach it and if the monitor stays on when you remove it, then goes off when you attach it again, you need the second type switch, if it goes off when removed, you need the always-on always -off first type switch. .

Hi there.
OSD Lockout or On Screen Display Lockout message is that irritating on-screen message that sometimes pops up when you switch on your monitor. This completely locks all monitor settings.
This problem has most likely happened to everybody at some stage or another. Everything has worked fine until now you turn on your monitor and have a message glaring you in the face displaying something about "OSD Lockout". This doesn't allow you to change any of your monitors settings, including the setting intended to turn off this message. While this problem mainly happens on HP monitors from my looking around I know that others have encountered it on other brands as well. The fixes I provide below should work on those monitors too so don't fear if your monitor isn't an HP model.
The HP Fixes
Plug in the monitor and power it up. Hold down the monitor's Power button until you get a message saying "OSD Unlocked". If the problem persists after OSD is unlocked then unplug the monitor from the wall, wait a few seconds (just to be sure I'd give it anything around 20-30 seconds) and then try again.
Instead of holding down the Power button, turn on the monitor and hold down the Menu button for 10-20 seconds. This should unlock the OSD.
Turn off the monitor, press down the Menu button and then turn on the monitor. Wait 10-20 seconds. This should unlock the OSD.
The Menu button may be stuck in a pressed in position. To get it "unstuck" you'll usually need to open up the monitor. If your not a seasoned veteran at opening up electronics (and knowing where all the screws go back into) then this could be tricky unless you know what you're doing. Unfortunately there are too many models of monitors for me to give a step by step instruction guide for you. If you have warranty this is where you should use it, I suggest you contact the manufacturer.
The AOC Fixes
Turn off the monitor, hold menu and power button together for 10 seconds then turn back on.
Currently these are the most commeon fixes.

I have an hp flatscreen monitor and when i turned the power on the button went down but never came up and the power is not on. now it seems like the button is stuck down. is there a way to take it apart...

Common problem with this model power switch plastic actuator is poorly designed with very thin piece of plastic lever that hold the button in place which breaks off after using many times.
You will have to take it apart and see the if the plastic button can be glued back inplace with silicone RTV. You may have to remove the broken button and use a piece of wooden stick to push the tactile switch on and off.
See pictures here:
You will have to remove the front bezel to get to the switch PCB assembly.

Have an HP LCD Monitor with a broken on/off switch.

j1hoo2, You will just have to go to YOUTUBE and search for things like::: lcd monitor disassembly or lcd monitor repair, or bad caps in lcd monitors, or repair of monitor SMPS/INVERTER power supplys. Yes!!! I have seen a couple of vids that show how to unsnap the rear plastic cover from the front bezel. That is the hardest part to do after removal of the monitor PEDESTAL. I'm louie12fix on fixya, or lmistyrel@
ps I've also heard that really dull table knives may work and also an old credit/swipe-card might work also.. I mean did an elephant step on the monitor on/off button???? Come-on, their not supposed to FAIL !!!

Turn the screen off with the power button.
Then press and hold "AUTO" and then press the power button at the same time. Your power button should go amber. Release both buttons.

This should put you into the factory service menu by pressing the menu button where you can reset the whole monitor back to factory settings.

When you are finished, just exit the menu, turn the monitor off with th epower button again, and back on normally.

Hope it helps.

There is probably some electronic malfunctions inside your monitor. Since I will not be able to actually check your monitor, the best solution for this is bring your monitor to a qualified TV/CRT technician in your area for proper diagnosis. He's the right expert and the second opinion to that kind of problem. Problems regarding inside the monitor are usually not fix-it-yourself kind of thing for non-expert like you compared to software problem, which can be mostly fix by yourself guided by an expert.
