Hello,

you can easily inspect the capacitors on the display and see if they are the fauly. Now does the screen work if you connect it back to the old machine, and do any other monitors work with this computer?

can you tell me more about the symtoms of this display, what does it do when you turn it on etc?

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on: Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.

Unless the problem is in the monitor, more likely the PC video resolution is too high for the monitor to work. Please read here:
http://www.fixya.com/support/r4873371-fixing_out_range_format_not_supported

You need to set your PC video resolution to the native resolution of this VL1919,
Which is 1280 x 1024 @60HZ

Please leave rating if it helps.

Also watch out for the caps to go bad in this monitor also.

Not sure if the VL1918 uses the same chassis as your, just remove the 4 screws and disconnect all the lamps connectors and other connectors.

bsims77010, Tell me brand name of electrolytic filter capacitors on the large "switch-mode-power-supply / CCFL inverter supply" printed circuit board. Are any of them SWOLLEN on the end that is up ??? You can see typical "failed units if you visit YOUTUBE for video clips that show owners/tech's that replace them with new ones and now have working units again. You must tell me more about this "keeps turning off" thing???? Is unit going to "black screen" only?? Or is it going to "black n blank" screen"??? There is a difference!!! If black only then 5vdc might be ok! If "black n blank then +12vdc & +5vdc sources could be in shut down mode. Do you see screen data with aid of bright flashlight held 1 inch from the "black" screen?? Once you have knowledge of what makes "raw white light" on reverse side of your lcd panel, then you will have clue to how the new screw-in, curlie-Q style CFL light bulbs work and what an "electronic ballast" circuit is. 12fixlouie
Post reply if you need further assistance.

You need to verify to find out if it is the monitor is bad or the PC is not sending the video signal to the monitor. Try another monitor with the PC, if you still have the problem then you need to fix the PC, if it works OK then it is the monitor problem.

More likely the power supply had failed, but more likely that it is already on its way out due to bad caps, see pictures here:
http://s807.photobucket.com/albums/yy352/budm/Princeton%20VL1918W/

http://s807.photobucket.com/albums/yy352/budm/Princeton%20VL2018W/

As you can see, 99% of failed monitors are due to bad caps.
