model group list, then check which group the current MA Board belongs
to.

Prepare both a good engine and an MA board, and check either of the
engine or the MA board has trouble by changing it with the good one.
"Hxxxx-xxxxxxxx" is printed on the label. The three or
four digits after "H" indicate the current model.
 Make sure the group is correct since even among the
same model projectors, various MA Boards may be
used.
 Even if 3-digit number; "HHH" of serial number
indicated on a label attached to the optical engine;
"FYMHHHNNNN", is different, this engine can be
used as the same type of optical engine as long as the
parts compatibility is maintained.
