    I have the same problem. It blinks blue for hours hours. It sometimes works by itself after hours of blinking, or if you tinker around with the cable and/or turning the computer off. I have no idea why this works sometimes, but it is definetly not a perm. solution. I just can't find the answer to this problem.

There is a field of capacitors on the power board that usually goes bad. I believe that there is a total of 6. When you look at the power board you should notice them. I have the capacitors if you need them. $2 each. Just check to confirm that they are swollen. and let me know the voltage and uF. good Luck. David

Along with the capacitors check the transistors for discoloration as that is probably why it turns on and off continuously. I found 4 bad capacitors and 1 bad transistor on my power supply board.

Why does my HP vs17 monitor screen keep going to blank black screen like it turned off but did' power button light is still on? Everything is running but no picture.....keeps happening everytime...

this old monitor has 2 issues.
1: it has CCFL tubes that love to burn out (backlamps)
most this old are long go, yell,dim.,blinking or DEAD.
2: push the menu button on front of mon. turn off power saver.

3: if the PC goes to sleep, or hibernete mode (parked)
then that is 100% normal
if you dont like feature then go to windows control panel
click power, ICON and turn off all monitor sleep /hibernate modes.

that assumes windows, no OS stated.

if the lamps are dead,
use flash light pointed to sceen, see data. ? bingo for bad CCFT tubes.
as seen here

My Princeton 19 inch LCD monitor keeps turning off and I have to un-plug it, wait, and plug it back into the wall socket for it to go back on. I replaced the multiple box and the power cord and am using...

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

My Princeton monitor will show the normal screen for about one second when I push the power button, but then immediately goes off (screen is black). If I push the power button off, and then back on it does...

It more likely to have the same failure as other Princeton monitors here.
Most common failure 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 goes wrong:

Screen isn't coming on. I have a Princeton VL1919. The blue light blinks when on and the screen is just black. I have tried it on all 3 of my computers and it won't work. Any help would be awsome. Thanks

Common failure on the Princeton monitors are caps failure in the power supply, look for bad caps (bulging top or seal), see failed Princeton monitors due to bad caps:
