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

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.

No picture - blinking blue light. My daughter was


There are a few things you can check. First, try to see if the monitor cables are firmly connected on both sides (computer and monitor) no need to remove any cable for now just check the monitor cables (ends should be blue or white on both sides) Then check if you got an imput button on your screen (like all TV and some monitors now has) This input gives you the choice between a few possible connections and it may be on the wrong one. Just cycle trough the input modes and I think you will have your image back. If Still, you dont see anything, try a different monitor or try to connect your monitor on a different PC/laptop. In fact blinking blue could be there because the monitor is awaiting a signal on the input it's listening. At worst it could be because your video chip/card dont send a signal to your monitor, could happen, but imo it's probably not the case.

Blinking Blue Light.. >.>


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!
