Question about Princeton Digital VL1918 Monitor

1 Answer

Princeton Monitor cycling on/off

My monitor is cycling on and off every 1-2 seconds and makes a pinging or clapping sound. I've followed the instructions posted here, and have disassembled the monitor. I've located the 3 capacitors, and they are slightly bulged. I've seen people mention soldering the capacitors...do I have to do that, or will they just snap on and off the board? Is there a specific way to remove the capacitors? I REALLY don't want to solder!

    I went and bought a soldering tool. Unsoldering and soldering the capacitors wasn't nearly as difficult as I thought it would be. My monitor is working perfectly now! Thanks!!!

First you would have to make sure that you get 3 good capacitors. The UF value has to be the same and just make sure the voltage is either the same or it can be higher. Also make sure the resistors physically are close to the same size as the ones your replacing.

Basically at this point you would have to unsolder 1 bad capacitor and then make sure you put the new one in exactly the same way the old one was in with the line facing the colored area on the board, that is the thing, they have to be put in this way for them to work.

You have to unsolder the old ones and resolder the new ones in, one at a time. They DON"T snap out or in. Unsoldering the old ones out and resoldering the new ones in is the only way to do this and fix your monitor.

Try looking for bad caps first, see example of failed PRINCETON monitors because of bad caps here: http://s807.photobucket.com/home/budm/allalbums
Post back what you see so we can guide you further.
The ticking sound is from power supply turning on and off.

Sounds like the monitor took a power surge. Monitor is probably bad but try hooking up the power to the monitor on a different power outlet and see if it turns on, if not then the monitor is bad and would need to be replaced.

Vl1918 it poweres on and shuts off.repeat


You need to replace the "buldging" capacitors as that is a sign that they are bad. Go to Radio Shack & they can hook U up with the parts. Here's a good example of how to do it, and I have to say that I followed these steps & now mine works: http://www.wizardanswers.com/liquidvideorepair.html
