Princeton VL1919 Monitor blinking blue light

The power seems to come on,. however the screen remains black for close to ten minutes as the blue power light blinks. After the ten minutes, the screen pops up and functions normally. Turning the monitor off then on yields the same result.

    Mine does the same thing. I have tried disconnecting and reconnecting cables, rebooting, and burning incense to no avail. Somewhere I remember reading that it has to do with the computers power save feature but even after I disable it, I am still having the problem.

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

Hello,

This usually indicates a power supply that is about to die. Heat buildup in the monitor case causes parts called capacitors to overheat and blow out. Check out our web site at: www.ccl-la.com/badcaps.htm We have pictures of what the blown capacitors look like. Open the back of your monitor and look for the blown caps. Replace all the ones that look like the ones in the pictures and you should be back up and running. The values you need to get are going to be marked on the sides of the ones you take out. Be sure to reinstall the new ones with the polarity stripe going the same direction as the old ones come out. You can order replacement parts from several places on the internet or we can supply them for you. You will need to use high temp caps that will be marked 105c, these are not available from Radio Shack. If you use ones that are not rated correctly then you will have more issues in a month or two. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping.

I hope this helps, If so please rate our solution.

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.

Try looking for bad caps first, see example of failed PRINCETON monitors because of bad caps here: http://s807.photobucket.com/home/budm/allalbums

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

I have an old Princeton monitor. The screen is black and the blue power button keeps blinking. Has anyone had this problem before?


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

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.
