I have two Princeton VL1916 LCD Monitors. The one on my wife's computer stopped working a couple of years ago. I assumed the power supply was bad. I replaced them both of them with larger 21" monitors, but occasionally used the one in my home office with a laptop computer. When we moved, I put both monitors and power supplies in a box.
Yesterday I decided to figure out which one works. I tried both monitors with both 12V 4.0A power supply blocks. The one that I thought was good is a little larger and not quite as heavy as the other one but neither monitor would power on with it. When I plugged the smaller power block into an AC cord (while not plugged into a monitor) the green light went on for a brief moment, then went out. Neither of the monitors would power on with it either.
What concerns me is something like bad capacitors in one of the monitors might have caused both of the power supplies to burn out. If that were the case, replacing a power supply without knowing which monitor is bad could be a total waste of money.
Any suggestions (other than throwing both of them out and buying a replacement to occasionally use with my laptop)?
(I might add that I am not competent with a soldering iron, and the only thing I have to test a 12V circuit is a probe with a light in it for checking the light and brake circuits on my utility trailer.)
