Monitror keeps cycling through on-off

We have a number of CTX monitors with failing power boards dropping out the back light rendering it black or appearance it is dead. Given the number of them we have seen it would suggest there is a possible weakness in the design and replacement is the only option

Sounds like your video adapter settings have been wedged. If you are running Windows XP Service Pack 2, you can use the following steps.

1) Boot the laptop into safe mode. Boot into safe mode with networking support if possible. This can be done by tapping the F8 key as the computer first turns on.

2) Once you are at the Desktop, right click on My Computer and select Manage.

3) In the window that appears, select Device Manager from the menu on the left.

4) Find Display Adapters on the right and click the plus sign. This will list the video adapter that you have.

NOTE: WRITE this down EXACTLY. You may need to go and get drivers for this. Seeing this is an older model, I doubt you'll need it, but better to be safe then sorry.

5) Go to your manufacturers support web site and download these drivers. You may not need them, but better to be safe then sorry.

NOTE: Skip step 5 if you did not boot with network support or cannot get to the Internet. This can be done from normal mode.

6) Right click on the display adpater and choose un-install. Hit OK on the window that appears and reboot the machine when the process is done.

7) The machine will take longer than usual to boot, as Windows XP is re-discovering the video adapter and resetting everything to the defaults. When it is done booting, the screen may look weird since the settings are now the defaults. You can the set them to what you want by right clicking on the desktop and selecting properties. Then go to the settings tab.

8) IF it did not re-discover the video adapter (this can be confirmed through the device manager), then go ahead and install the drivers. Windows Update will most likely also have the drivers.

NOTE: This process should work with Windows 2000 as well, although I was not able to test it. The only issue I can think of is that it may not auto-discover the video adapter, and you would have to manually download and install the drivers.

I have same problem my monitor keeps turning on and off continuously and some times its working properly but working properlt is rarecase
plz help me to solve it as fast as possible...

Sounds like a power supply problem in the monitor to me...

If you have checked the monitor on multiple computers, then the source of the problem is not your video adapters, or drivers installed. The monitor appears to be defective. Oddly enough, I have the same problem with my CTX monitor. I sent them an email this morning, and hopefully will receive a response soon. I'll keep you up to date.

I had the same problem used with my mac mini using the DVI connector. The problem continued with the monitor not plugged into anything.

The Solution: When I unplugged the monitor cable from the monitor & cycled the power for the monitor on & off, the monitor cleared itself. I rehooked everything up & it works perfectly.

Additional info- possible cause - I was using an external, filtered fan to cool my small computer. When I placed it too close to my computer, I I began hearing a every 1/2 second electical popping sound. I don't know if it was an electrical power problem since all were plugged into the same power strip, or if there was magnetic, radio or other electrical problems caused by the close proximity, but that was what was occurring at the moment the monitor then went out. You should review & share with others what led up to the failure, so we don't duplicate your meltdown!

I also just recently started having this problem. If you look at the power brick the power indicator flashes on and off with the monitor. I think that the power brick is bad. I switched to a different monitor and the computer works fine. The en-9110 cycles on/off with or without a computer attached. I contacted Envision about an RMA.
