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

try taking the batteries out or go to the shop where you bought it and go from there...good luck lol :-P

That is the problem with the standby section of the power supply. A continuous flashing indicate a shorted component usually a small diode.

Try it with anotehr PC first, otherwise will more likely to be bad caps: http://s807.photobucket.com/albums/yy352/budm/Princeton%20VL1918W/

Please post back what you find.

More likely the power supply had failed, but more likely that it is already on its way out due to bad caps, see pictures here:

As you can see, 99% of failed monitors are due to bad caps.

Remove the stand and all he screw from the back and the bottom edge. See my pictures fo VL1918 which is similar to 1919.

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.

Try the monitor with another computer or with a laptop (as an external monitor). If it is working, the problem is related to the main unit. This case, have the main unit be checked by a professional.

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

My VL1919 has been having this issue off and on for a month or so now. It happened three times in one day today, so I decided to do something about it. I opened up the monitor and poked around a bit.
I found three electrolytic capacitors on the backlight inverter board were bulging, two of which had just started to leak: The capacitors were placed directly above and next to a large, flat metal heat sink. I say above with respect to the flow of air due to convection, and next to because the heat sink also wraps around, enclosing the group of capacitors on one side. The heat sink sits flush with the circuit board, turning the board into a front enclosing face. When reassembled, the metal housing sits a fraction of an inch above the sink, forming a back face. This assembly is at the top edge of the circuit board, so the housing then takes a 90° bend to form a top face. These capacitors seem to get almost no air flow... Together with the heat coming off the sink, it appears the engineers have created their own little capacitor oven. Capacitors immediately adjacent to the affected components, but without blocked air flow looked completely normal. Looking at the traces on the circuit board and location of other components, the capacitors could have easily been moved out of the hot spot. This is either an act of gross negligence, or an intentionally created post-warranty failure point, designed to avoid market saturation. But that might be too pessimistic... "Never attribute to malice what can be adequately explained by incompetence." Anyway, I scavenged a few capacitors off an old computer power supply to replace the damaged parts (one 470uF 25V two 1000uF 10V capacitor, both rated to 105°C). To avoid a repeat performance, I soldered some short extension wires to the replacement caps and moved them out to an open area of the board, being careful to give the high voltage components plenty of breathing room. After reassembly, the monitor powered right up and came online. I guess the real question is how long it will stay this way.

If you feel confident take the monitor back cover off and replace the 3 bulged out capacitors
