Repaired but it took an EPROM, everything was fine except vertical
height and centering.

Finally figured out how to get into the service menu and corrected
that, but now have the following problem.

WE CAN'T GET OUT OF IT !

The manuals for chassis' that are similar have procedures but they do
not work. So how do we store new values and exit the service menu in
these things ?

Thanks.
