RV Repair: electrical, electrical problem, problem thanks

Question
I have a 2000 Damon Intruder.  I am on shore power.   My lights went out.  I tried other switches, and the lights came back on.  When they came on my Fan Tastic cycled like it wanted to open.  When this happened my TV continued to work. Now I have lost all power.  How can I begin to track my problem?

Thanks Richard

Answer
Electric power is not my specialty, but if I were to guess, it sounds like a convertor/inverter problem. I would call Customer Service at Damon. They have experts that could help you troubleshoot your electrical problem.
Sorry I couldn't help more,
