If you bought this RV used, as indicated, there could be several things to look for.
Is there a battery in the popup, and is it good? The converter is also a battery recharger, and a bad battery can cause problems for the converter.
Unless you know who the seller was on a real personal basis, there is also no telling to what may have happened to the pop-up previously. My first instinct was that this pup may have been hooked up to a 240 power supply, which still could have happened before you bought it. It's hard for me to imagine that the seller never connected to an electrical outlet in the 10 years before you bought it, but as you indicated in a PM to me.
I would possibly suggest checking out the converter first. Let me find you some previous posted links on how to do this.
