No signal, blue power light blinks with beeps

The monitor would lose its signal and then come back on, but finally did not come back. Now, with power supplied, just the blue power light blinks with beeps, but no video signal.

    Mine does the same thing. May stay on for 3-5 minutes and then goes blank with the blue light remaining on. Seems like the touch switch may be a problem. Its a great feature but hasn't gained wide acceptance. Maybe it has a short life.

have you tested the power supply connection feeds? test each connector I think you will find your power supply has failed on either the 5 volt or the 12 volt side more than likely 5 volts are down' the agp adapter needs 5 volts to run. since you have changed out every thing else I would replace that or test your dads power supply in your computer, that should do the trick

SOURCE: Power Light Blinking & Black Screen

A blinking blue light indiactes that your power-inverter board is not putting out what it should. It needs an overhaul which may be a simple as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

check the capacitors inside the monitor, as they may be broken, and they start screen up, just change em and it should kickstart fine

I have a hp w2207 flat screen monitor. when turning power on, power blue light blinking and no picture. what can I check or look for to find and fix the problem?


That blue blinking light could be the fact that there is not a signal from the PC to the monitor itself. You could have lost your video card, corrupt driver for video card or monitor. If you have a PC with separate video card and a mother board video output, try switching to the one you are not using and rebooting the PC

It sounds like either your monitor or video card inside the computer is bad.

If the monitor is showing the "No Input Signal" message then the video card inside the computer is bad. The monitor is ok otherwise it would not be able to display the No Input Signal message.

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 computer 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 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.

This is usually a sign that there is no signal going to your monitor, check all your cables and then reboot.

My monitor is not responding to anything. what can i do aside from rebooting?


do you see the light blinking in the monitor? I mean the POWER led light up? If so, then the monitor is ok and is working good. It is your CPU which has a problem and not sending digital signal for the monitor to display.
Try to turn off your computer. After 3 minutes turn it back on. then notice if you will hear a short beep from the CPU. That signals a successful video initialization. If you went through that process, then your computer will get back to life.
However, if you dont hear a short beep from the CPU, then definitely your CPU is frozen therefore there is nothing to display to the monitor.
You need to open the CPU case, pull out memory modules then plug them back in. Then try booting.
If not successful, try to open case and pull out the processor. Put it back in after 30 seconds. Try booting again.
Do ALL THESE while your PC is UNPLUGGED.
Good luck.

check for loose connection of the video cable connection on the system unit (CPU). blinking may indicate that there is no signal transferred from the cpu to the monitor!
