How do I repair my 19in LCD monitor, it receives video signal, but goes black screen?


Connect the "bad" monitor to the VGA-out port on a notebook/laptop computer, to see if it works normally when connected. If not, then the monitor is "dead".
If it works fine, check the "screen-resolution" of the computer's video-card, to see if the values exceed the capability of the monitor.

Keep getting "frequency out of range" meassage


Sounds like there is an issue with the video card settings versus your monitor.

Try the following:

1.) Press F8 on boot and select VGA mode then once into the OS reset the video card options

2.) Try another monitor

3.) If you have video card, swap it out. If you have onboard graphics put a card in

Cheers...please post your results.

When I re-boot my PC, my monitor blinks on and off


It's normal behaviour - it blinks because during boot the pc starts with the default VGA driver, then unloads it (the monitor shuts down as the video card is disabled) then load the appropriate video driver (the monitor starts up again as the video card is activated properly).

When starting the system the monotor appears to boot up- there is a flash of an HP screen, then all goes black...?


Try a different monitor and see if that fixes it - however I suspect your video card might be on the way out.

If you're familar with computers, open your case and check the card is seated properly etc. If not, take it into a store to get the card tested/try a different card.

Hope this helps,

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Problem watching movies & playing games(screen flashes black on & off


HI
This may not help, but you can try to lower the resloution to another widescreen format.
I'm thinking you may have your resolution maxed out and the video card is having problems with the movie games because of that. Possibly not enough video memory
Movies will work fine at lower resolutions, Not sure about all the games but they probably will too.

Screen stays black


Try using a different monitor if you have one available, or disconnect the monitor from the computer and then turn it on. If you see a logo or color bar or message saying no signal, then your monitor is OK and you should take a look at your video card.

If you suspect your video card, there is very little you can do with a no video situation. but one thing you can do is to remove the video card completely and wait for a few minutes. then put it back in and try to start your computer. This is just in case you have corrupted video memory keeping it from functioning. otherwise, replace the card.

In the case that your video is built into you computer, buy a new card and disable the onboard video in the BIOS. That will take some browsing in the BIOS setup, but it shold be fairly easy to find. once it is disabled, the new card will be able to function and you should be ok from there. Otherwise, it's motherboard replacement time.

Loss of DVI video/black screen


The problem is probably related to it showing the wrong video card. I would see if there is any help for everquest on changing that and if you cannot figure it out I would reinstall the game and that should fix your problem, keep in mind that you may have to uninstall in order to reinstall properly.

HP Pavilion - the monitor flashes off and on


Pls uninstall the video card drivers and reinstall them.

Also pls look for any graphics driver updates from the manufacturer.

Also pls check if the cable from the power supply for the graphics is connected on the motherboard.

Pls check with another monitor if it is doing the same thing.
If the same happens with another monitor, then it is an issue with the video card..
