Question about Princeton Digital VL180 18.1 in. Flat Panel LCD Monitor
I have a princeton vl180 monitor which is missing 2 ribbin wires (never had them, bought it hoping i could get replacements). they seem to b about 7/8" and 1.5" respectively, i don't know how long though. they seem to cross like an 'X' from origin to destination, and said crossing would look like a rubber 'X' folded horizontally. is there somewhere i can purchase replacements for them? the gent i bought it from hunted for them and couldn't find them after he sent me the monitor. he had been using the panel alone without the stand frame in some application, then the need was negated, so he sold the monitor. one receptor 'socket' has '30' at 1 end and 'G' at the opposite end. the other receptor 'socket' has '45' at 1 end and 'A' at the opposite end. all without the quote marks (i hope this info is of some help)
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.

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.

We had a power surge and my VL2018W LCD monitor stopped working... blank screen and flashing blue light.
I carefully opened up the back and found the power board (the one the AC plug goes into). There were about 5 electrolytic capacitors that were bulging (but not ruptured). There were 3 with the values listed by the original poster (470uF @ 25V) and 2 with 1000uF @ 10V.
I scrounged a couple of 2200uF@10V caps for the last two and bought 3 470uF @ 35V caps from Radio Shack (P/N 272-1030).
Luckily, the monitor came right back up and seems to be OK. It was out of warranty, so there wasn't a big risk.
Just increasing the working voltage won't do that much for you. If any caps are bad, just replacing them with the same value is good enough, but a higher working voltage won't hurt (usually means a bigger cap).

Boot up in safe mode and selct VGA support, then set the video resolution to your Princeton VL2018 native resolution mode (1680x1050 @60 Hz)

Hopefully you monitor doese not have the same problem (bad caps) just like the other VL2018 as shown in my pictures here (but it will fail for sure later on):

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
