Re: Princeton VL1715 monitor's pwr button is "locked."...
I have resolved this situation on other brands by holding down one of the advustment buttons while holding the power button in. You will see a message about "unlocking button" and a sliding bar if you find the right buttons.

Try looking for bad caps first, see example of failed PRINCETON monitors because of bad caps here: http://s807.photobucket.com/home/budm/allalbums
Post back what you see so we can guide you further.
The ticking sound is from power supply turning on and off.
Sounds like the monitor took a power surge. Monitor is probably bad but try hooking up the power to the monitor on a different power outlet and see if it turns on, if not then the monitor is bad and would need to be replaced.
No . I am not suggesting that you flash the BIOS . I am suggesting that newer drivers are likely available and you should download them and install,especially the video card driver. They even have diagnostic software fot your model, if you have or can borrow another monitor that will work.
Their seems to be 12 different video cards on your model alone. If this doesn't work , judge me not harshly but give me a chance to have you try something else.
From what you say there is probably not much you can do with it, the parts inside are SMD, to small to work on. If you could still see txt on the screen when you shine your torch, it could be fixed by replacing the back lighting PCB.
Try this! Copied right from the Princeton Graphics support pages. (bless their hearts....'course it wasn't "real" easy to find; it was posted for a different monitor for a different problem... but it seems to work for different monitors... Mine's an LCD19D ... and no, it wasn't posted for my monitor either.)

4) You will see a message "RESET EPROM" 5) Power off the unit
6) Plug in your VGA cable

Have you disabled your onboard video in the BIOS? Boot your machine with the vga cord to the motherboard. You need to get into the BIOS. Depending on the make of your machine you need you will need to hit the del key, f2, or even f1. Go to the periphrial setup and disable your onboard video. Save the BIOS turnoff the computer and plug the monitor into you vga card. That should do it.
To change it back to your motherboards vga just reverse the instructions.
Let me know what happens.
