There could be several things causing this issue. The power surge could have damaged the main board, power supply, graphics card or on board graphics, cd-rom drive ect. The problem is that one of these things could be bad and you need to figure out what it is. The first thing I would do is disconnect on component at a time and then re-boot the computer and see if you get a picture. Pull the cd-rom drive,then the floppy drive,then any modems. If you still get nothing then try the hard drive. If you disconnect the hard drive your operating system won't start but at least you should see the BIOS star screen come up. If that does not work then try taking the power supply from the working computer and install it in that one if the plugs are the same. You could try using the graphics card from the other computer but it may not be compatible. There are PCI,AGP, and PCI-Express cards. Make sure the graphics card slot on the broken computer is the same as the one on the working one. Also remember to ground yourself to the metal case of the computer before touching any components or static discharge could damage that part you touch. If you try all these things and it still does not work than it is probably a bad mainboard. In my experience when a processor goes out the computer will do nothing...no boot up and no lights.

Hi,
quite straight forward and simple Fix.
it,s the card that the Monitors plugged Into.
there are different Types. Pci-Agp-Pci-express.
Assuming that your cards are identical, as mentioned above.
remove The power Cable from the Computer. take off the left hand side panel, usually 2 screws at the back of the case. Locate the graphics card. these are mostly secured by 1 screw to the back panel ( internally ) there is a release catch on the motherboard, gently pull tab downwards, to allow the card to be removed. replace in reverse order. plugging in the power cable finally. connect the monitor, and startup the computer.

Try replacing the cable first, or try a diifferent monitor, otherwise open the case and look for a card that has the vga(monitor plug) on it-but your existing one may be built in to the MOBO in which case you will have to disable that driver, then pop in your graphics card in an empty pci slot and download a new driver

I have the same problem with at least 6 GV800s that are clone...I dont know if the originals will have the same problem. The problems occured after thunderstikes. All went DEAD and send them to China for repair. I have a few cameras connected to this card using shielded cable...and some others using UTP cable using video balloons. The UTP is not shielded and I start suspecting the damage is from these cameras.

i believe you may have answered your own question here because what you are stating is a malfunctioned monitor if you plugged other monitors to the cpu and they worked and the monitor in question is not working maybe it was a storm surge and since it did not have a surge protector then maybe the monitor is shot and you may need to replace the monitor...

hope this helps

I have a gateway desktop computer. Recently moved


Before you actually replace the power supply, check some other things first:
1. Wall socket
2. Power strip/surge protector
3. Power cable
4. On the back of the computer, where the power cable plugs into, is the red switch set to 115? It should be 115.
5. Make sure that the power cable is not connected to a regular extension cord. Power cable must plug directly into a surge protector that is not daisy-chained to another power strip, surge protector, or normal (household) extension cord. Surge protector must be directly plugged into wall socket.

If none of the above solve the problem, open up the case and ensure that all power connections are secure. Also check ALL other components' connections. Any loose connections can cause problems for you.

If everything is secure and the problem persists, replace the power supply.

The monitor was working one day and the next day, it would not come on, screen black. My grandson has had the monitor for almost three years.


Hi,
I'll hope for the best and assume the simple fix first. Check the plug at the back of the monitor to insure it wasn't pulled out slightly. Sometimes, moving something around can cuse the plug to lose proper connection.
Also, check the power source to insure that you have power to the unit. We had a lightening storm recently and the power strip surge protector did it's job. I turned it back on and everything powered up again.
I hope this helps... Good luck!

My acer screen just went blank after i turned my computer on this morning. it stayed white....


Loose Connection Possibly. If not try Unplugging from the Electric.Leaving for a 5 Minutes. Then plug all cables back in and try again.

If this dosn't help then you may have had a power surge. Its hard to say what has happened if you have had a power surge, they can do all sorts of things

Dell Monitor Blank


It seems the problem my not be to involved.
1st. Did you take the monitor apart.? If so, you should back track and find what you had missed.
2nd. If you had not taken the unit apart after the power surge, you will more than likely have to, in order to repair your monitors problems.
3rd. This will most differently require the removal of power supply and the replacement of 5 to 8 Capacitors.
4th. If you are not experienced in the replacement of electronic items on a printed circuit board, Please do not attempt this repair.....
3rd. If the unit has any kind of warranty, you may want to pursue a warranty repair.
Do Not Tell Reps. That You Had A Power Surge.
No electronic equipment is covered under Power Surge Faults.

If you do feel confidant in the removal and replacement of these items, please reply to me here or at my website and I will explain in detail, how to get to and remove supply and what to look for in repair.

Blank Screen


Be sure that the power cable and the video cable are plugged into your monitor, the power cable is plugged into a good outlet, and the video cable is plugged into your computer. It's possible that you simply have a loose cable.

If everything is installed correctly, and if the screen is completely blank (no "cable disconnected" or "test mode" messages), then it sounds like your monitor is simply dead. Since there was a heavy wind storm recently, it was probably hit by a power surge. If you don't already, I recommend that you use a surge protector for all digital equipment.

There is power but no display


Your symptom is commonly caused by failure if the inverter circuit. It is made by Sampo. The inverter powers the backlights. Replacing the inverter is the first step to resolve the problem.
