1. No Video Signal on the Display or Signal is going in and Out:

a. Please test your RJ45 cables with a Fluke or similar tester to make sure that all the wires are

connected and the distance is within the limits.

b. If you are using patch panel or and RJ45 wall plates, the distance will be reduced, please do a

direct connection bypassing all additional equipment.

c. Please try to re-terminate your CAT5/6/7 wire to 568B

d. Reboot your source and try connecting it directly to the display to see if the video and audio will

pass-

through. If so, please go into the menu of the source and select an actual resolution that TV

handles instead of AUTO – which is default.

e. If your sources is a computer (laptop or desktop), please enable the DVI output.

2. IR Signal is not passing through:

Make sure you have IR RX and IR TX connected to its respective interfaces. If not, you may have

burned the IR sensor on the IR RX or and IR TX and therefore should replace them.

3. No Audio Signal or Garbled Audio

a. Your display might not be able to accept audio formats that you are trying to send, most

displays can only accept PCM or Stereo Audio as they only have 2 speakers. Please try selecting

PCM or Stereo audio under the source audio configuration.

b. If you are connecting Source to an AVR with the AT-HD4-V110SR and AVR is connected to a TV

or a Projector with a standard HDMI cable or another extender and your AVR is only not getting

full Dolby Digital or DTS audio. This issue is related to the EDID issue of the AVR, we suggest

changing an AVR for a better one or using AT-HDSYNC (Atlona HDMI Corrector) to fix this issue.
