Thanks, ***** ***** nothing you can repair yourself, the systems rely heavily on interacting micro computers. There is less than a 1% chance that I can coach you to full diagnosis and repair on this, and that is only if you have an electronics background.

Let me know if you would like me to locate a local mitsubishi dealer for you, that company has a program that plugs the contractor directly into their technical diagnosis base in Japan.

If you want me do do that, tell me which direction you are from the center of the nearest city and I will see what I can do
