Hello,

I have a Buffalo III SE which is no longer locking onto a signal. The only input on it currently is the spdif, the mute led comes on, lock led does not. Have tried multiple sources which output spdif. Any troubleshooting suggestions would be greatly appreciated. Here are some readings I'm getting on my multimeter. The readings which were inconsistent were those going to the IVY. Readings were 1.4V except for G-Negative on the left side was 0V.

5.2V at the input terminal from placid power supply.

Trident on left side of Buffalo
G-IN - 5.2V
G-OUT - 3.28V

Trident in the center
G-IN - 5.2V
G-OUT - 3.26

Trident on the right
G-IN - 5.2V
G-OUT - 1.17

AVCC
G-IN - 5.2V
G-OUT - 3.6V
G-NC - 3.27V
These readings match on both sides of this module.

Connections to IVY-III
G-Positive - 1.41V
G-Negative - 1.41V

ON left side (next to "Russ White" writing)
G-Positive - 1.41V
G-Negative - 0V
