No video

  • Are the green LED’s on both the transmitter and receiver units. If not check that the power supply (psu) is connected and the light on the psu is lit.

  • Are the jumpers in the right place
    On a tx 111 for vga both jumpers should be set at the top labelled vga
    For Rgbs the jumper on the left should be at the bottom and one on the right at the top.
    On a RX212 the jumpers for composite are the same as component (YpbPr)
  • Is the audio input level too high? The audio level should be set to line level (0dB or 700mV peak to peak) to prevent interference.
