Symptom Checks
Key on remote is pressed but
nothing happens
See if the upper LED of D-TUNE is fast-blinking while
pressing key and aiming remote at IR sensor on Plasma
Display. If it is not -– check the batteries in the remote. If the
batteries are good – check the cable connections between
the Plasma Display and the D-TUNE.
Image is not locking to display
or is incorrect proportion
The output of the D-Tune is 720 x 480p. Some displays
need to be told it is a video signal or it may see it is VGA
thus misaligning the image.
No RS-232 communication Check baud rate is set to 9600. Cable may need to be
nulled.
RDS Info does not display Poor reception will cause dropped characters from the RDS.
Also, not all stations broadcast RDS.
Cannot switch to a particular TV
channel using channel +/-
browse keys.
The channel is selectable by browsing keys only if it is
marked as “valid”. To be marked as “valid” the channel must
have a good TV signal during the “channel scan” operation.
Repeat the channel scan (making sure aerial/cable
connection is good). Also the channel validity can be edited
manually.
