Turn the set on using the power button on the remote control after
the Power LED has lit up Red. (When the Power LED is blinking
Orange, the cooling fan is operating.)
This indicates that the set is heated and has not cooled off enough.
The lamp may be malfunctioning if the power does not turn on even
after the above steps. Please consult your nearest dealer.
•
Are the batteries dead or inserted incorrectly?
•
Is the remote control sensor in direct light of florescent lamps or other
strong sources of light?
•
Is the antenna or antenna cable old, broken or shorted?
•
Is the antenna cable connected properly?
•
When using a VCR and selecting channels on the TV, is the TV/VIDEO
mode for the VCR set to TV?
•
Is the antenna facing the right direction?
•
Is the antenna receiving any signals reflected off of mountains or
buildings.
•
The image distorts when channels are changed.
•
When using 16:9 image software, there is no picture at the top and
bottom of the screen (cinema vision size software, etc.).
•
Has the screen position been changed?
If so, adjust screen positioning.
•
Press the INFO/RECALL button.
During VIDEO input, channel number is displayed until an image is
displayed.
•
If there are no problems with image or sound, it is the sound of the
cabinet shrinking due to room temperature changes. This is not a
malfunction.
•
This is the sound of the internal (DLP TM ) starting UP. This is not a
malfunction.
•
DLP TM is manufactured using an extremely high level of precision
technology, however sometimes some parts of the screen may be
missing picture elements. This is not a sign of a malfunction.
