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:
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. "

Welcome to Fixya

First thing to do is to check all physical connection of the monitor if both ends are intact. Install the driver of your video card. If you have other computer, try to plug in the monitor to that computer, just to make sure that the video card of the 1st computer is not the problem.

Please reply back to this email for any update.

Thank you for using Fixya!

VL 1716 monitor. The display blanks out after 20-30 seconds. When I turn the power OFF anf Back ON, the display comes back normal, then blanks out agin after 20-30 seconds. The power light stays green.

This is due to system goes to stand by mode or Hibernate mode. To disable, go to power management and disable or incrase the time for the same.

Revert back for more assistance. Also give your valuable feedback/rating on the same.

My princeton VL2018W will flash the screen when first powered on but goes blank after. With repeated unpluging, the display used to stay, but no luck

99% will be bad caps in the power supply section. Take the back off and look for caps with bulging top, replace them with good quality caps such as PANASONIC FM or FC series from DIGIKEY.

Princeton VL1715-1 no display

From what you say there is probably not much you can do with it, the parts inside are SMD, to small
to work on. If you could still see txt on the screen when you shine your torch, it could be fixed by
replacing the back lighting PCB.

Hope this helps
Have a nice day.

Monitor displays breifly then goes to blank screen

The power -inverter board probably needs an overhaul.
I redo many of these.
If the screen was pinkish or flickering before it finally got to this point, it is possible that a bulb has gone bad.

Looks like one of your backlights is bad, first indication is the red or pink tint, replacement of the lamp is fairly easy. If one lamp is bad the inverter will not work. You can get a replacement lamp from Mouser electronics for about $12
