I have a Princeton VL1918 LCD monitor. It worked fine for almost 3 years. Now each time I switch on the display comes on and stays for a fraction of a second and I get black screen. I don't hear any sound or switch powering off like that as suggest with some of the postings. The power light stays on fine. Any help is appreciated.

- Buddy,
Thanks for the response! I looked inside and everything looks good. I do not understand what you mean by backlight problem. I do see the display very clearly when connected to my laptop but only it disappears in a few seconds. I don't get NO SIGNAL. When I refresh the display from my laptop it shows up again.
You have a monitor with a common problem. After a few years some LCD monitors
will blow a power supply. The problem is caused by parts called
capacitors overheating in the confined space of he monitor. If you are
good at electronicsrepair/soldering you can usually fix he problem. Check out a few pictures on my web sitewww.ccl-la.com/badcaps.htm
You can take the back cover off your monitor and look for the bad parts,
replace any that look like the pictues and your monitor should work
fine. The capacitors do need to be installed with the correct + and -
connections, note the stripe on the old one and insert the new one the
same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. If you don't see any bad capacitors then the next thing would be bad CFL (backlight tubes) in the screen itself. If it is that then the monitor needs to be replaced because of the tech skills needed to replace then. I hope this helps, if so please rate my solution.

I have a Princeton VL1918 Monitor with built in speakers. the volume is to low. how do I increase it? I have the speaker set on the computer to the highest setting. Is there a volume on the monitor itself? If so, how do I get there?

It is a bit blurry and I want to know if there is a way to adjust the focus, or sharpness. None of the 4 buttons in front seem to have that function. Thanks!

The Mac Mini that it's attached to is generating a proper video image, since I can mouse and click and type productively during the two seconds of darkness, just not see where I've aimed at.
I can avoid the issue if I don't let my CPU go to sleep, thereby forcing the monitor to run the screensaver all night. However, the Mac ran slightly funny the next day, so I slept it that night, and the next morning the monitor was worse. Each "off" was accompanied now by a "Chuff!" sound; this went on for several minutes, then switched to the prior type of "click," before eventually staying on.
I have not yet located a flashlight. Will the test work in ambient light, or does the room need to be darkened?
