Sounds like a hardware problem - you'll need to either replace it, or take it to an authorized repair dealer.

If you can try another monitor, you'll know for sure the first one is bad.

Replacing it is probably cheaper.

Dell Inspiron 2350 All-in-One Desktop PC Fault Flickering Touch Screen


It could be 1 of 2 things, either your monitor is going out on you, or your graphics adapter is going bad. Depending on how long ago you purchased it, and from whom, I would contact Dell service to find out if they can return it, or give you any suggestion.

I have an hp pavilion dv5. When I power it on the computer starts up but the monitor doesn't come on. And then it does this series of beeps. Beep beep beep. It does that series 5 times


Before you begin
Check the following items before using the steps in this document:
•If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
•Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
•If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
•Disconnect all connected devices except the mouse, keyboard and monitor. This includes thumb drives and camera-type memory cards from card reader slots.
With the devices disconnected, restart the computer. If the computer starts and the monitor now displays a picture, a device is preventing the computer from starting. Update the BIOS to resolve this issue.
Step 1: Connect the computer to another monitor
Connect another monitor to the computer to determine which device has the problem (the monitor or the computer). This step is very important to help you determine if the problem is coming from the computer or the monitor. If necessary, temporarily connect the computer to a friends monitor for troubleshooting purposes.
After the monitor is connected, turn on the computer and the monitor. What happens?
•If the newly attached monitor does not display anything , disconnect the cable and continue at Step 2: Is the video connection damaged?
•If the newly attached monitor displays the first startup screen(s) but then goes black, there is a problem with Windows starting. Skip to step 5 .
•If the new monitor works , the original monitor or its cables are faulty. Do the following:
1.Replace the monitor power cable.
1.Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.Replace the video cable.
Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.If the monitor does not work after replacing the cables, replace or service the monitor.
Step 2: Is the video connection damaged?
Inspect the video cable and video connectors for damage. Check for sharp bends or breaks in the cable and bent or broken pins at the connectors. With the monitor and computer off, try to straighten bent pins with a small metal tube, like the tip of an empty mechanical pencil or the tip of a retracted pen.
Figure 1: Video connector
If you had to straighten any pins, reconnect the monitor making sure that the video cable is firmly connected and then turn on the computer and monitor. If the display is still blank, continue to the next step.
Step 3: Resetting and updating the BIOS
You can use these steps even though you will not be able to see anything on the monitor.
In case an item was changed in the BIOS, such as the primary display device setting, use the following steps to reset the BIOS back to its default configuration:
1.Turn on the computer and repeatedly press one of the following keyboard keys. Press the key about once every second for 5 seconds after turning the computer on.
◦For HP and Compaq computers that came with Windows 7 and Vista, press F10 .
◦For HP and Compaq computers that came with Windows XP, press F1 .
◦For Compaq Presario desktop computers built prior to 2002, press F10 .
1.Wait another 5 seconds.
1.Press the F5 key. This restores the default settings of the BIOS.
1.Press the Enter key. This accepts the changes.
1.Press the F10 key. This saves the changes.
1.Press the Enter key. This saves the changes and exits from the BIOS.
1.The monitor should display the first screens received from the computer (the logo screens). If not, find and download the latest BIOS update if one is available for your computer.
1.If a BIOS update was not available or the monitor is still blank, continue to the next step.

My emachine T1742 desktop will not turn on. When plugged in the power supply's fan turns on, cpu fan doesnt start, both hdd/power led's flicker and pressing power button doesnt power on/off system.


Disconnect all the devices from the computer(tower) including keyboard, mouse, monitor(everything)..even the power cable

Now keep on holding down the power button on the computer tower for 15-30 seconds..

Now release the power button, plug in the power cable, monitor, keyboard, mouse and turn on the computer...

If it works, great!!!

Otherwise, take it for repair..

Got a compaq desk top model SR2177CL went in and adj. hibernation settings now the screen keeps flickering what is that?


Hi i'm Rain.
It sounds like the settings you have selected may not be what the factory decided. Return the settings back to the way they were.
check to see if that corrects the problem. { Note always reboot after changing settings to ensure that the change takes affect}.
Turn monitor off wait a few seconds then turn back on.
if problem is fixed you can retry to make the changes .

Monitor comes on for a few second flickers and goes black


This sounds like your back lights are going out or the power supply section has a problem.

If you turn the computer on then look at the edge of the screen if you see a ghost image then it would confirm the back light problem. That can be caused by several internal problems. You should check with a different monitor or try your monitor on a different machine to confirm the monitor is the problem. Check your warranty to see if you can get it replaced.

My hp pavilion dv6000 laptop does not turn on, the blue buttons light up, but the screen stays off


Try it without the rechargable battery connected sometimes the battery shorts and causes problems.
Do you have FN[function] keys at the left side. touch FN key with something else and see if screen comes back.Sometimes you can turn off the screen to send it to the back connected monitor.Connect (extra if you have) an external monitor to the back (vga) connector.If that shows, then you have to ""flutzz" with the FN(function) & F1-F12 keys

Monitor flashes


I had the same problem with the flashing screen. It turned out to be the anti virus - anti spyware software was somehow screwing with the harddrive files. I uninstalled the anti virus and spyware program and that stopped the flickering. Hope this helps.
