Checking the model group list
4. Referring to the Technical Information (No. TI08-30) and obtain the latest
model group list, then check which group the current MA Board belongs to.
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.
Locating the trouble (Optical Engine/MA Board)
5. 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.
