Display in trouble
Screen with spectral
colors
Color production of R,
G and B is not correct.
Black screen
Are the sockets SC2001
and SC9001 connected
correctly?
Are the socket SC2001
and SC9001 connected
correctly?
Are the contact terminals
of the DMD, formatter
PWB and cLGA dirty?
Are the SC2001 and
SC9001 connected
correctly?
Does the color wheel
turn?
Does P9402 have the
correct motor drive
voltage waveform?
Is the waveform at pins
(18) and (20) of IC9202
the 400MHz sine wave?
IC9202, IC9101, X9101
or their peripheral
circuits are faulty.
Does the pin (3) of
IC9201 have the correct
voltage +1.8V?
Are the signals fed to the
terminating resistance
(39W) of RDRAM
(IC9203)?(DQA8 and
DQB8 are unused.)
Re-assemble the DMD,
the optical mechanism
and the formatter unit.
Do the colors return to
correct colors when the
process menu is
entered?
Poor adjustment should
be a likely cause.
Perform readjustment
according to the
adjustment method.
Color wheel is faulty.
IC2002 is faulty.
IC9401 or its peripheral
circuits are faulty.
Is the lamp lit on?
Check the color wheel
sensor unit.
IC2001, IC2007 or their
peripheral circuits are
faulty.
Is the correct voltage is
supplied to the each
connector of power and
ballast unit?
Check the ballast unit
and the power unit.
Does pin (2) of P2004
have 150Hz pulse signal
in no-signal state?
Does pin (9) of IC9301
have the correct voltage
(+23~+26V)?
Is pulse wave in voltage
at pin (14) of P1701?
IC9301 or its peripheral
circuits are faulty.
Miscellaneous
Equally spaced white or
black vertical stripes
Black horizontal band
IC9203, IC9101 or their
peripheral circuits are
faulty.
IC2007, IC2002 or their
peripheral circuits are
faulty.
Does pin (13) of IC9301
have the correct voltage
(-26V)?
Does pin (49) of IC9301
have the correct voltage
(+7V)?
Is the fan rotating?
Check the fan circuit.
Double-check DMD and
cLGA units.
