HP L1906 19 in LCD blinking poer button

I have an HP L1906 19 in LCD Monitor. This is the second monitor that this has happened on. From a cold boot the monitor will not display and the power button will just be blinking green. After about 10 minutes the display fianlly comes up. I have bout 100 of these monitors where I work and I am startign to get a little concern that something else is going on. This has happened only in the last two weeks. The only thing that has changed is that I upgraded our anti virus sofware on all my PC's. I have never seen this happen before. Any thoughts

    I am experiencing the same problem - I did not upgrade any software however or make any changes to my current system. The computer and monitor were working fine. I shut the computer down two nights ago. In the morning the monitor would not turn on and the monitor light kept blinking green.



    Can anyone help?

These things do fail, I don't see this as an unusual problem.

SOURCE: monitor to black, power LED blinks, hard re-boot and it works

Take a look at your power saving settings. It sounds like the monitor is set to sleep after 20 or 30 minutes. You may want to change your setting to "never". The settings are under Control Panel - Power management

SOURCE: Experienced general power failure in house lasting

It may be coincident that the power supply circuits may have failed since it may already have failing components on the circuits, DC filter caps will be the first thing to look for inside.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

SOURCE: Monitor will not turn on. Green light on power

Sounds like some bad capacitors, probably on the power board. I've had the same problem with a Dell 17" monitor, a 42" plasma tv and a 37" LED LCD tv, all now fixed and working properly.

If it's under warranty then send it back to be fixed. If not then you have two options.

1. Pay a tv repairman or similar to fix it for you. Probably the most expensive option.

2. You could remove/replace them yourself if you're handy with electronics, or know someone who is. All you need is a soldering iron and a screwdriver. The capacitors themselves are quite cheap and easy to replace

They should look something like this:
drunknmonkey_4.jpg
As you should be able to see, the one on the left is bulging. The blue stripe with the arrow tells you that the lead on that side is the negative, the positive lead should also be longer than the negative one.

Tools needed
-----------------
1. Soldering iron.
2. Solder - not acid core
3. Phillips screwdriver
4. Flat head screwdriver
5. Wirecutters


Instructions
--------------
1. Unplug monitor and open case.

2. Identify power board, it should have a lot of electrolytic caps on there and obviously should be connected to where the power lead is attached.

3. Identify the bad caps, they should be bulging and/or leaking, although not always. Note down the three values for each cap (eg 220uf, 16v, 105c) and their approximate dimensions, and get new ones, preferably Rubicon or Panasonic, the link below will help you chose some good ones. If in doubt you could remove them and take them to the shop, but you'll have to remember where each one goes and which way round it was (take a pic).

4. Very carefully heat up the contacts on one side with the soldering iron, and rock the cap the other way, then do the other side, keep doing this until the cap comes out.

4. Replace with new cap, making sure that you observe the polarity and make sure it's securely seated and soldered in. Make sure the solder is neat, tidy and doesn't contact anything else. If there's any solder left in the holes then you'll have to heat it up or remove it before you can get the new cap's leads through. Once done properly trim the leads off so they won't cause any problems.

5. Replace casing and test. If it doesn't work then you'll have been a bit messy with the solder, tidy it up and try it again.

Here's some links to help you:

Desktop runs but won't boot


Normally if the hard drive is bad you will get some type of message on the screen.

If it sounds like it is running but the screen is blank, then try another monitor. Maybe the monitor is bad. Try another monitor. Borrow a monitor from a neighbor, friend, relative or co-worker and put it on the computer. If the borrowed monitor works, then your old monitor is bad. If the borrowed monitor does the same thing, then your video card is bad.

If it does not seem like it booted up all the way then try the steps below.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button. And if that's true maybe you was operating off the battery the last time you had it on and since the power cord is bad, it was not charging the battery so the battery is drained and the power cord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.



Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Could be the resolution too high for the monitor.
Try to press "F8" during the "Starting Windows" message, then select the safe mode or VGA mode.
After logging in check the resolution and if needed reduce it.

Could be also a video driver problem.

Use the same "F8" trick to get to the safe mode and reinstall the video driver.

I hope this will give you some ideas

Blank HP w1907


If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.

Volume pop up in the middle of my screen


no photos of said window presented? i cant see them?
must be OSD? the monitor brain on screen display (menu)?
even with the DVI cable pulled?
only a monitor stated, w1907, no PC
some monitors have button lock
read the manual ?oops HP deleted it...
it tells you to push the menu key on the monitor for 10 seconds
and it unlocks. (4 buttons right side left button is MENU)
doom?
that power deal sounds super bad, like the power supply is bad.
if the monitor fails by its self not plugged it to a PC
then the monitors is bad.
try a reset on it? ( power off for 1hr, or off then plug in with power button held? or power on with menu held (wild guesses but common practice)
ok found your manual page 4-8 shows menu page advanced
list line in list factory reset.
but if the keys are dead, and power lamp failing
the power supply is no good or worse. worse is always possible.
and expensive


ever see the support page, read the guides
