Wow...I'm having the exact same problem with a 4222. I have it in the reapair shop right now. The problem was that there was not Fujistu repair in my area or even within a 2 hour drive. SO I had to set up my local service cetner as a Fujistu service...I di all of the leg work for it.
I hate doing other people's jobs!
Anyway now I'm waiting for the service center to receive a service remote...meanwhile, my customer's is busting my chops.
I'm looking for that remote if any one has the ccf for it.
The Fujistu service tech told me how to figure out which board is bad. send me an email if you want the notes I took. Leave your fax number in the email and I'll fax them.
It seemed easy enough to fix, but I didn't want toi risk it.
