I agree with the other commentators that you need to make sure the power is good. I would definitely try with a good power conditioner (and voltage regulator).
Also, has the unit ever been exposed to too much electricity such as a lightning storm. On conradjohnsonowners.com there was a story of a person who had electrical damage done to his CJ unit due to a storm and it was unrepairable. Perhaps something like this may have happened that damaged the electronics, perhaps in the on/off circuit if that is the problem your having?
I would probably give Ed a call at Conrad Johnson, he is very helpful.
