Possible Solution
The projector automatically detects the input signal
y
format. It will maintain the aspect ratio of the projected
image according to input signal format with an Original
setting.
If the image is still stretched, adjust the aspect ratio
y
in the Display settings of the Advanced menu in the
OSD.
A projector LED has failed and the projector will auto-
y
matically shut down. If the problem persists, contact
Optoma.
The projector has overheated. The display automati-
y
cally shuts down. Turn the display on again after the
projector cools down. If the problem persists, contact
Optoma.
If the projector fan fails, the projector will automatically
y
shut down. Clear the projector mode by pressing and
holding the Power button for 10 seconds. Please wait
for about 5 minutes and try to power up again. If the
problem persists, contact Optoma.
The battery may be low. Check if the LED indication
y
from the remote is too dim. If so, replace with a new
CR2025 battery.
