If your battery has a bad cell, no amount of charging will fix it. Test it, and run a voltage test on 12 v going to battery

The battery charger part of the converter is not working properly. Assuming that the converter itself is OK (pretty good assumption), it could be two things. Either the breaker that brings 120 VAC into the converter has popped. Or the fuse that brings 12 VDC out of the converter has popped. Both are easy to check. Remember that if a breaker has popped, you can't simply move it back to the ON position. You must first move it further toward OFF, then snap it back to ON.

All of these symptoms are signs of exactly what I posted earlier. The lights are running from your battery, which is badly discharged but still in the circuit. This means that the battery is at least OK, and the main battery fuse (located at the battery) is not blown.
Shore power is getting through to all the wall outlets, which means the shore power 30-amp breaker is not popped. That doesn't leave very much that could be wrong.
The converter should be putting out a strong 12 VDC, which would brighten up the lights, but it is not. Either the converter is not getting AC power at its input, or it is not delivering DC power at its output. You need to investigate both.
If you determine that the converter is getting input power, but there is nothing at its output, it may have an internal fuse. What make an model is your converter?
The converter does not make any noise when it first starts up, so you can stop listening for it. The converter may have a small internal fan that will come after the converter has been handling a heavy load for a while - but your converter is not handling any load, so the fan will not come on.
It is possible that the converter has gone bad, but it is unlikely. And you can't determine whether this is true until you confirm that the converter is getting AC power at its input, and determine whether it is producing DC power at its output.
You can plug and unplug shore power, and connect and disconnect the battery, all day and it won't tell you what you need to know. Do you have a test meter? If not, you should find someone who is experienced with electricity.

SCR stands for "silicon controlled rectifier". It is a type of electronic switch. Does your converter have an SCR? You need to tell us the make and model of your converter. If your converter has one, there is no easy way to know if it is bad, and if it is, the replacement is both painful and expensive.
