Please post back what you find.
That was EXACTLY the problem on my VL1919. The average person should simply get a new monitor, as this is not an easy repair unless you already have the right capacitors on hand and a soldering iron. Almost everything must be taken apart in order to get at the power supply board with the capacitors.
Two pairs of capacitors were bulging - 1000 uF, 10V near the heat sink, and 220 uF, 25V in the center of the board. I was able to find 1000 uF, 16V capacitors, bag of 20, on eBay for $3 with free shipping. There were also 470 uF, 35V caps by the same seller, bag of 20 for $3. These were all rated at 105 degrees C. Be careful about going to Radio Shack - when I checked, those capacitors were only rated to 85 C. Since this is a heat-related failure, those wouldn't last long.
I replaced the 1000 uF caps with the higher voltage type because they would fit, replaced the 220 uF with higher voltage and capacitance because they would fit, and while I was at it, replaced the 470 uF caps near the heat sink, even though they were not yet bulging.
