Monitor is less than 2 year old. Just went blank.
When you turn the power on, the power light comes on and the LCD shows red/pink with the proper display for about 1 second and then goes blank.
I am going to reseat all connections, but wondered if it is a waste of time.
Replacement LCD units are about $90, and a new one is about $300, so it is worth a little poking around time.
Can anyone give me some direction here?
I had the same problem for the past couple of weeks: first it was intermittent and then it just went dead completely. Something you may want to try (depends on model, but worked on mine) is to disconnect the power cord to the back of the monitor. There should be a little black piece of plastic that sticks through a slot in the metal plate behind the power inverter. Try pushing this up (might be a reset of some sort) and then plugging things back in.
Before you replace anything pull the light out and then you can see if they are in good shape, outside of the screen is not too hard but delicated take easy, and check o site of lcd repair I think this is the name.
I have the same problem. You turn it on and it will flash the correct colors and screen shoot for a half of a second then goes black. The green power indicator shows the regular green light as it did when working ok. I turn the computer off and the light turn amber as it should. I plugged it into another computer and same problem. Any help out there before I use it for an anchor on my boat.
Looks like one of your backlights is bad, first indication is the red or pink tint, replacement of the lamp is fairly easy. If one lamp is bad the inverter will not work. You can get a replacement lamp from Mouser electronics for about $12

THe AC adapter (power supply) for my Princeton VL173 went bad. I discovered it was the PS and not the display by plugging in an old adapter from an HP printer that I had replaced. The input plugs matched and the power out profiles were nearly identical Only very minor differences). It was just a stab in the dark, but it works! Now my display is 12 years old and still going strong. I hope this helps.
bsims77010, Tell me brand name of electrolytic filter capacitors on the large "switch-mode-power-supply / CCFL inverter supply" printed circuit board. Are any of them SWOLLEN on the end that is up ??? You can see typical "failed units if you visit YOUTUBE for video clips that show owners/tech's that replace them with new ones and now have working units again. You must tell me more about this "keeps turning off" thing???? Is unit going to "black screen" only?? Or is it going to "black n blank" screen"??? There is a difference!!! If black only then 5vdc might be ok! If "black n blank then +12vdc & +5vdc sources could be in shut down mode. Do you see screen data with aid of bright flashlight held 1 inch from the "black" screen?? Once you have knowledge of what makes "raw white light" on reverse side of your lcd panel, then you will have clue to how the new screw-in, curlie-Q style CFL light bulbs work and what an "electronic ballast" circuit is. 12fixlouie
Post reply if you need further assistance.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Princeton monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
floresa57, After lcd panel "flashes" is the lcd panel "black" or is it both "black" and "blank" when you perform the flashlight test that every LCD owner should know how to do and interpret the results? Do you have warranty? If no, then read more responses in my FIXYA profile for clues on what YOU will or what YOU won't do to fix your BLACK SCREEN monitor!!! Floresa57, the basic principles of design and operation of your Princeton VL2018W are same as all other brands of Fluorescent backlit LCD monitors!!! It can be fixed. READ, READ, before you do anything. Understand the reason WHY your monitor is now black and lifeless. Follow all the LINKS to other web sites so you will be informed and less likely to be overcharged on a repair job that should have cost less than $50. Good luck Floresa57. Rate this on FIXYA if it was of some use to you. 12fixlouie
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 electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.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 am using this great LCD for about an year. But few times in the past my LCD didnt show up the display though the Green light was still ON, turning off the LCD and opening it again always solved the problem. But now My LCD completely went blank. Turning off/on didnt work at all now. I've tried couple of other tweaks mentioned on this site but they didnt work. I am just seeing a blank screen with green light ON. and ya theres a very low hissing sound coming from the LCD.
From your description of the issue, the LCD and or hte inverter has failed. If less than a year old, contact Princeton Digital for warranty repair, if outside 1 year, it is likely cheaper to replace than repair
