5. Troubleshooting

There are no field serviceable parts or circuits in the device. If you think

that the device is malfunctioning, please first try to reset to the factory

default settings (using the RESET button on the IR remote control), and

set the output either to XGA (Press MENU + ▲) or 480p (Press MENU

+ ▼) to obtain an image on your LCD.

If you are having trouble displaying a picture from an HDMI™ source,

ensure that the display device connected to the AC139A is HDCP

compliant.

For HDMI™ compliance, when the DVI input is selected, and HCDP

content protection is detected on the signal, the HD15 analog output is

blanked. The front panel input LED will blink when this condition is

detected. The Digital DVI output will be active when connected to a

HDCP compliant LCD (such as a display with HDMI™ input).
