Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

I have a acer.x223w when,it powers up the.screem stays black, n i get a blue blinking light on.the bottom


I disagree with ikkenom only due to the symptom of the flashing blue light. This would indicate to me that the monitor is not getting any display signal and is in sleep mode at least the is what happens on my Samsung monitor. Used to be that they use a two color led in the monitor, green when ON and getting display signal and amber or orange when in sleep mode. I would check the computer by trying a different monitor. If you have a second monitor, great, if not, maybe a friend will let you bring your computer over and try the computer with their monitor. Could also be a display adapter setting. Do you get any change when you first turn on your computer? i.e. Do you get the BIOS or manufacturer screen when first turned on? Also if you disconnect the monitor cable from the computer and power cycle the monitor, do you get a No Signal display for a few seconds before the monitor goes black and the blue light starts flashing?

Let me know what happens with the testing above or if you need further instructions to carry out testing.

Thanks, Jim

Power is on but after 2-4 seconds display turns off but power is still on where the power light is in blue.it's not in sleep mode where the power color is orange.it just goes back to normal at random...


Without looking at the monitor to confirm this, I suspect you have failing capacitors which power the HT circuit, simply, the power needed to light the display, is leaking to earth, capacitors have lost the ability to store the charge necessary to illuminate the screen, which is why it is working erratically.
You need to get this checked out by a TV technician.

Monitor will not awake from sleep mode. Pilot light is amber when asleep. If the monitor is turned off pilot light goes from amber to off or black or nothing. Turning the monitor back on the pilot light...


That means your monitor is not receiving a signal from your video card.

A couple things to check:
*Make sure your cable is ok - unplug and replug the cable to see if it is a loose connection. Or try a different cable.

*Make sure your computer is not in sleep mode - Move your mouse or otherwise ensure your computer is awake and sending a video signal

*If you have another computer, try the monitor on the other system and see if it works.

When I start the computer the Windows XP Logos light up on the Monitor (HP w1907) when the computer starts the Logo disappears and the monitor goes to sleep


If this monitor (HP w1907) is going into sleep mode the normally blue power led will change to yellow. This indicates loss of video signal or possible out of range resolution. If the picture goes dark and the power lite stays blue, you have a backlight malfunction. It can be an inverter power fault but this model mostly has worn out backlights causing a shutdown condition.

Monitor wont stay on- blue light is on. but screen keeps going blank.


Have you tried the monitor on another computer? If so, and it works, the issue is with your graphics settings on your computer. LCD and plasma based monitors often come with a protection circuit that disables the monitor if the synch or refresh rate are beyond it's capabilities. this is to protect your monitor from damage.

Do not exceed your monitor's max resolution.
Resolution is determined the following way:

Width x Height @ Refresh Rate
For your model:
  • Max Resolution 1440 x 900 @ 75Hz
More detailed information about your monitor can be found HERE. If your monitor is still under warranty, and you find it to be faulty, you may be able to send it to the manufacturer for repairs.

Sharp light turns green thern turns yellow screen goes black


it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.

although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode

some one else suggested that i remove and reseat the video card

hopefully one of those will work for you

Monitor Problem


I fixed the problem by acquiring a recovery disk that booted me into the bios screen and the screen came on. I then changed the settings, I still don't know why it happened in the first place though!

Thanks anyway though
