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

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: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

Hp pavilion f1703 blue monitor power button flashesw/ dark screen


Have you tried connecting this monitor to another computer, even a laptop. This would tell you whether the display is bad or the video card is the culprit. I suspect the monitor's power supply is dying. Taking it to a pro for repair should cost @55.00. Buying a new monitor @ $100 - $125.

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.
