Subject: Fix for blue-screen coming up, preventing video from passing.
When the AT-HD-SC-500 is on a Firmware Version below 1.3.31, there are certain scenarios that can cause the following symptoms to occur:
When the unit is powered on, only the Power (PW) LED is illuminated.
The HDMI video output cycles between no video, and sometimes results in these blue screens with glitches/artifacts:
To restore the unit, follow these steps:
- Disconnect and reconnect the HDMI Inputs 1 & 2.
- Ensure that there are active video sources at HDMI Inputs 1 & 2.
- Press the Input button until either HDMI Input 1 or 2 LED is illuminated, and the expected picture is visible on the display.
Now the unit is restored. To prevent this from occurring again, install Firmware Version 1.3.31 to the AT-HD-SC-500.
