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

SOURCE: Princeton Monitor VL1917 - No Power

This is the way how to examine what's wrong with your LCD monitors. After you turned your pc on, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

Hi Alvie
I Just checked the specs on both the card and the monitor. It should work no problem. If for some reason you notice some lag or flicker in the monitor, go to this page and download the updated ForceWare graphics drivers.

SOURCE: I have two CTX monitors.

well by ordering the caps replaced that is a start for the first one it should work like new when you get those replaced, second monitor it could still be a cap issue but you need to look and see if they are doomed if hey are popped then they need to be replaced, one of the reasons they shut down is variance in the power supplied to the ccfl if it variances too much the unit shuts the vga and thereby the ccfl unit off.
fyi you don't need all the caps replaced just the popped ones.

SOURCE: i have the princeton VL193 monitor. Its blank, no power light

Most common failures 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 to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Testimonial: "thank you the explanation sounds like its right on the mark. Unfortunately, I see these being sold used for under $50 so it is not worthwhile for me to repair as I don't have the expertise and I would think I would be charged at least that by a shop.I was hoping there was a reset button as I think the monitor succumb to an outage. Thanks again. "

My Princeton Monitor VL2018W does not have sharp colors.


I fixed many of these, look for bad caps.

Make sure to replace the whole set on the low DC power supply side with good caps, not from Radio Shack standard electrolytic type.

I have a Princeton VL173 Monitor and when I switch it on the screen comes up for about 2 seconds then goes blank,and each time I switch it on and off by the monitor it only stays up for a second or two. I...


Would think that this one could be a bad capacitor problem.
The unit is pretty easy to dissasemble, and remove the screen itself from the housing, look at the power board, the main board in the middle of the unit, and see if you see any bulged or leaking capacitors. they look like little beer cans...should be flat on top. If you see any bulged or leaking capacitors, order replacements at mouser.com and replace them with a soldering iron. Should fix the problem. Bad caps are a very common problem in all kinds of electronics.

Princeton Monitor is "out of range"


Hi,
The monitor is not getting a video signal. This is probably an issue with your computer. It could be a memory, hard drive or motherboard issue.

Make sure you are getting power to the pc (fans running, hard drive spinning...etc). Then check your memory. Try switching memory slots, or try different memory.

Turn on computer and see if you hear any bios beeps.

Try a different hard drive if you have one.

Good luck,
Hank

Princeton monitor, model # vl1916 Wont power on.


Hi, Billman11, maybe you can repair or maybe not. You need to tell me some stuff first. Need the approx age of the display. Next thing! Does the monitor have external power supply? (black box, sit on floor type) or internal (line cord to wall outlet, and other end to monitor) What exactly happens if monitor is connected to afully booted PC with known good vga output and u connect the flat screen lcd and push the power button? Is lcd panel still pitch black? no flicker or anything? Can you see the power on led indicator even?? From waht you already described it sounds like a Switch-Mode-Power-Supply failure. Each lcd monitor has 2 or 3 printed circuits inside under metal shields beneath the black plastic case covers. In your case, we will want to investigate the board that the line cord plugs into. That will be the smps board, or the little black box on the floor. If you want to try fixing this monitor you can get back to me at louie12fix on fixya or lmistyrel@ aol.com Yes, I'm a vet and spent a year on Kanghwa Do, Korea 67-68 Work for company that provides electronic hardware/software to the gaming industry and located northern Illinois. BYE for now.
