<If a test pattern is not displayed>
The sink device or cable 1 has a problem. Check the power supply, connection and input
switching (if there are some) of the sink device.
Perform the cable test (P.48) for cable 1 if necessary.
<If a test tone is not output to the sink device that supports audio>
Check the following items: volume of sink device, mute setting, the presence or absence of
headphones connection, and audio input setting.
<If there is no problem or test pattern is not displayed in a specific setting>
Perform the source test (② Fig. 3.3).
Immediately after the sink device and GF-100 are connected, the EDID of the sink device will
be copied into the GF-100 automatically. The copied EDID is used by the switcher during the
source test.

[Fig. 3.3] Source test
■ Checking source status (P.19)
Check if source signals can be detected correctly (P.21).
<If signals cannot be detected>
Check the power supply of the switcher, connection and channel switching setting. If the source
signals still cannot be detected, perform the sink test of the switcher (③ Fig.3.4).
<If signals can be detected>
Check the following items: the resolution of the source signals, the presence or absence of
audio and HDCP, color space, color depth (Deep Color), and other items.
If source signals that are not supported by the sink device are sent, change the BD player
settings and EDID of the distribution amplifier, and other actions in order to resolve the problem.
If no problem is found, perform the sink test of the switcher (③ Fig.3.4).
