If you have problems with your converter, try these suggestions before calling Customer Service.

The power indicator is off If the power on indicator is not on, make sure that the wall outlet that the power adapter is plugged into is a live outlet and that it is turned on (if it is switched).
No video and no audio Make sure that the TV is set to the correct input, and the source device is setup to output an HDMI signal.
Has video, but no audio Set the HDMI output resolution to a lower value, such as 720p.

Try other audio modes and settings. Change from Bitstream to PCM, or select a 2-Channel or Stereo Audio option (instead of Surround Sound).

Image quality is poor Because of the limitations of legacy analog composite video output, the image quality will not be as good as a digital or HD source. There will be a softness to the image and the colors will not be as vivid. Small text and details will be hard to read. This is normal and not a problem with the converter box.
