    I was having a similiar problem so I left the monitor plugged in for a few weeks. I believe there might be an internal battery that was low. Now I can turn it off in front like normal. But I am still unable to use his monitor. The blue screen comes on and it says in a red box no sync. I have the original book but it does not tell me how to sync it and I don't remember I haven't use this monitor for years. Can you help me with the no sync problem?

Ah A simple one. simply unplug the power adaptor and take itno a repair place or radio shack and ask them to measure the output to see if theres 12 volts DC on the plug?? Good Luck

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

SOURCE: 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.

"no signal"


"no signal" means that the monitor is not receiving a video signal from your computer or laptop. This is normal if the compouter is OFF and the monitor is ON. Is the computer still on and connected to the monitor?

The monitor shuts off. Turning the power off


the monitor is going into power saving mode ... it can happen if it is not receiving any signal from the pc ( pc is not running or booted properly, bad video cable connection monitor to pc) or the pc is itself in suspend/standby mode.

When it's turned on, the light on my Princeton monitor blinks...


I just did this capacitor replacement today after reading these posts. It worked great! I used 470uF
35volt caps from radio shack. There are three 470uF caps two right next to each other and one off by itself on the printed circuit board. The values are easily seen on the side of the capacitors. Open the monitor by removing the screws and prying the halves apart using a large straight edge screwdriver. There is a metal cover over the printed circuit board that will come loose after removing screws around its edge. There are several wire sockets that must be unplugged to allow the circuit board to be flipped over to reveal the capacitors. The board itself is held down with three screws
Once you identify the capacitors, use a fine tipped soldering pencil to melt the solder holding the capacitors in place and remove them. Position the new caps with the dark stripe matching up to the lined marks on the board, carefully apply just enough solder to each terminal to hold the caps in place. Reassemble and you're done.

Wont work with new computer


Since this was a new out of the box computer, Safe Mode was not allowed. In order to change monitor settings (resolution), I had to use another monitor, in this case a newer CRT. With the CRT, the computer booted up, no problem. Once booted, I turned down the monitor resolution and saved. Now when the Princeton LCD was plugged in and the computer restarted, everything works fine. Now the resolution could be set to limits of the monitor.

Using with a Mac


Looks like a power save program has hibernated your monitor. Look in Control panel settings to see if the power settings hibernate your monitor. Reset to never and this may fix your problem.

Drivers usually do not fail after 20 mins it is usually a software option set incorrectly.

Also, check the Bios program for correct settings or options.

I haven't had a Macintoch in a while but, this may give you some where to look for the solution

Good Luck
