Troubleshooting
Power
To function correctly, the HTT50 must be supplied with the appropriate power. If the power LED near
the top right corner of the board is not illuminated, power is not applied correctly. Try the tips below.
HTT devices have specific power requirements. Ensure the correct voltage and sufficient
current are available to your device by consulting the Power table.
Check the power cable that you are using for continuity. If you don't have an ohm meter, try
using a different power cable; if this does not help try a different power supply.
Check the power connector in use on your display. If the connector has become loose or
you are unable to resolve the issue, please use the Contact section to reach a friendly Matrix
Orbital support representative.
Display
If your display is powered successfully and connected to an HDMI source, the video feed should appear
on screen immediately. The video signal should be clean, and the picture should fit the viewing area of
the display. If this is not the case, check out these tips.
If you are connected to a single board computer, such as a Raspberry Pi, and your screen
displays a white screen on start‐up, or slowly fade to white, please check the Config.txt file
to ensure that the display is properly configured.
If the display is flickering, or if the display’s backlight is not consistent, try supplying
additional power through the display’s barrel jack.
If your display shows picture but there are white lines along the edge(s) of the display, your
display may be receiving the incorrect number of pixels. The HTT does not have a resolution
scaler, and therefore the appropriate 800 x 480 resolution must be specified for all the pixels
to be used.
If there are large black bars on the edges of the display, or if the video image appears to be
offset, please use the Contact section to reach a friendly Matrix Orbital support
representative
