TV (probably) and MW are 120 volts. Means you are getting 120V into TT okay. Try plugging in anything that is 120 volts into all the receptacles and see if they work - hairdryer, table lamp, etc. or use a voltmeter.
If only 12 volts inside TT when connected to tow vehicle, then battery and converter are not working. The battery could be dead if the converter is not putting out anything. How old is the battery and is there any electrolyte in the cells? You might try connecting your tow vehicle's battery to the TT (disconnect old battery first) with jumper cables and see if the 12 volt system inside the TT works via the TT's battery connections.
If you don't have a voltmeter, I would go get one. Check and see if the converter is putting out 13+ volts right at the converter panel (remove cover to get to connections).
