My monitor no display and light is blinking


Hi,
if the monitor light is blinking this suggests that, there is no display signal coming from the tower. This could be because of the following .

1. Bad video card 2. Bad video software

To check,where the problem is , power of the system tower and remove the power cord from the back of the tower. Press and hold the power buttoon for 10 seconds and the reconnect the power cord and turn the tower on. Check if there is any display or the status of the light changes from amber to green for even a small instance.

If the light changes to green and back to amber the video port on the tower is bad

Alternatively you can connect the monitor to another desktop or laptop to check if the same is working correctly.

Thanks for using fixya

Aux power led light is amber on dimension E521


I think your problem is your memory or video card.

Below are some steps that I recommend.

When you plug in the power cord is there any lights whatsoever on the computer?

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 computer 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.

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.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.


Below are links and info I found from Dell's Website based on your model.

Controls and Lights Front of computer:

Power button - push button

Power light
green light - Blinking green in sleep state; solid green for power-on state.
amber light - Blinking amber indicates a problem with the power supply inside the computer. If the system cannot boot and there is a solid amber light, this indicates a problem with the system board (see "Power Problems" in your Owner's Manual).

Diagnostic lights
four lights on the front panel (see Diagnostic Lights.)

Standby power light
AUX_PWR_LED on the system board

Hard-drive activity light
green light - When the computer is reading data from or writing data to the hard drive.

I have a optiquest Q20WB monitor when i push the power botton the green light flashes but the monitor doesnt come on.


More likley to have bad caps like other Optiquest monitors as shown in my albums.
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 OPTIQUEST monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Compaq presario S0000/8000 won't turn on. Green


try reseating the VGA cable to from your monitor, also reseat the Video card if you have an expansion Video card on your system, then try starting your computer again if the green blinking lights will still be blinking, if so turn your Computer off again and try removing your memory rams from its memory slots then try them One at a time and try from one slot to another if you have at least 2 memory cards on your system, by doing this you will atleast find out if one of your memory cards are faulty or if one of your memory slots on the motherboard is faulty again try one Ram at a time then turn the system on to see if the system boots or not also to this to trying both slots as well if the system turns on then possible either one of your rams or one of your system boards memory slots can be faulty, this process take time and patience but this is what 99.9% of all computer technicians do to isolate the issue.

Optiquest q20wb LCD has black screen & green power light flashing


Hi Rickyknows2,
If you are not hearing any beep I assume you are having problem with your video so, please ...
- open your PC and check whether your video card is well placed (sometimes it looks fine but you never know) remove it and put it back.
- If you used to remove often the cable from the PC, it might be that the pins from the monitor cable are even broke... please check.
- try to find another video card and replace it just to make sure its the video ...
- last... reset the bios (but I doubt that this is your problem)
chsers ..

Viewsonic Optiquest Q20wb green blink light


It's an issue with the power supply, most likely the Capacitors (one or more) may be shot. Open it up if it is out of warrenty, look at the capacitors (they look like cans), if they are bulging at the top or even sides they are bad. This is a common problem with this monitor. Crappy Caps used in manufacturing. Replace all the caps with same rated caps and you should be good. Do your research on how to desolder the old ones off and proper installation of the new ones.
