SEIKO EPSON Revision:C
CN1201 Lamp Lid Detection SW
The power can turn on and the projection starts, but
instantly the projector changes to the Lamp Error mode.
(refer to 3.2.1 "LED Indicators" (p. 3)) The power turns
off after a certain period of cooling. But the error mes-
sage continues to be on.
CN1202 PS Ballast (SCI)
The power can turn on and the power indicator blinks,
but the lamp is not ignited, so no image is projected.
After a while, the projector changes to the Lamp Error
mode. (refer to 3.2.1 "LED Indicators" (p. 3)) The
power turns off after a certain period of cooling. But the
error message continues to be on.
CN1203 Control Panel
Even if the AC cable is connected, the power indicator
is not lit. The power button does not work. (the same
status as CN2200 PS Ballast (PS))
CN1204 Photo Interrupter
The power can turn on and the projection starts nor-
mally. But even if the lens shutter is closed, the projec-
tion continues fully and the lamp keeps on. The AV
mute function does not work when the shutter is closed,
so the sound continues to be on. If the shutter kept
closed, it may be deformed or damaged, so be careful.
• Note: The control of AV Mute from the Remote Con-
troller is effective.
CN1205 RC board
The power can turn on and the projection starts nor-
mally. But the control from the rear does not function.
The control from the front is still effective, so if the
RC’s signal reflects from the screen, the control from
the rear might be effective. When checking, send the
signal to the back of the projector only. Otherwise, this
error can be easily slipped over, so be careful.
• Note: The setting of the RC receivers (active/inactive)
is available from the menu. So, check the setting of
the corresponding receiver before applying the rem-
edy.
CN1300 TH board
The power can turn on and the projection starts, but
instantly the projector changes to the Fan/Sensor Error
mode. (refer to 3.2.1 "LED Indicators" (p. 3)) The
power turns off after a certain period of cooling. But the
error message continues to be on.
