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:

Hello.Ihave a princeton vl1919 monitor.The problem is when you press the power button the light comes on for about a few seconds then goes out then you hear a tic tic ticing noise can i try and replace the...

Try looking for bad caps first, see example of failed PRINCETON monitors because of bad caps here:

The ticking sound is from power supply turning on and off.

Princeton Monitor VL1919 won't turn on during boot up.

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.

Where can I find the driver for a Princeton VL1919 monitor

Princeton Graphics VL2018W monitor does not require any drivers to function. If you have problems changing resolutions, color depth, or refresh rates, Please consult your video card manufacturer for a video driver or support. Your system will not identify the monitor if video drivers is not installed properly. I agree with this statement. You dont need drivers for monitors 99.9% of the time. Usually you video card is what is wrong if u cant change the resolution.

Monitor goes to sleep after 30 minutes vl1919

Welcome to FixYa! The default power saving feature is turning the monitor off. To change the settings go to the Desktop>Right click on it>Properties>Settings and you will see power saving settings where you can choose "Never turn off" or a longer time interval. These settings can also be found in your Control Panel for all of the Power Saving features for the computer, monitor and hard drive. Steve

Monitor dark for 20 minutes before turning on

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: 71706a0.jpg 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.
