Monitor flashes on then goes black.

Check the VGA cable connections at both ends, also try the monitor on other PC to so you will know for sure if it is the monitor or the PC Video card problems.

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)

Almost all LCD monitors use kind of the same enclosure. On the back or on the bottom there may be two screws. If so, remove them. If not, no worries. On the bottom you should find a couple of indentations in the plastic where the front and back join. I like to use a Radio Shack fiberglass flat bladed diddle stick. Put this into the indentation and push up. This should release the bottom. Now the trick. Use this diddle stick (it must be flat bladed) on the front. Using only your fingers gently lift the plastic case on the front away from the screen. You should see the metal case of the screen. Begining at the local right or left put the diddle stick between the metal only part of the screen and the plastic front. Reminder. This stick must be between the metal screen enclosure and the plastic front only. Once in this position, you can slide the stick upwards along the metal case. As you do the plastic case will pop away from the rear case. Provided there are no screws you missed. Now do the same on the other side and then the top. You should now have separated the front case from the rear case. Next take apart the metal shielding (usually screwed together). There may be metal tape placed in strategic places, make sure you gently unloosen this tape and reapply when you're finished. Hope you know what you're doing from here!

The Q7 has a tendency to burn up transistors and a high voltage capacitor on the one half of the inverter board which is part of the power board.
I have repaired 1/2 dozen of these with that problem.
Only way to tell for sure would be to open it up and look at it.
If you can do that and send me a picture to [email protected], I may be able to confirm this.
The other possible problem could be a bad bulb, but since it is fairly new ? that is probably not the issue.

On mine I pulled on the round cover where the base attaches to the screen. It came off and there are 4 screws underneath. Remove those screws that hold on the base

Hi,
There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed.
Let me know if I can assist you any further regarding this.
Best wishes,
Graemevm
