SONY STR-DE545 Stereo Amplifier/Tuner no radio
I an integrated 5.1 tuner/amp.
Will not output anything from the tuner. Has a slight hum but nothing else. Doesn't seem to pickup any stations either. All the other inputs work fine. If i unplug the tuner module off the board the humm goes away. How can I confirm it is the tuner module before I order a new one. I found some schematics that lables the pins of the 15 pin tuner: Stereo Tuned T.Mute S.Data S.Clk DO S.Lat L CH but i have no idea what sort of signals I am suppose to expect from these. Any help appreciated. Thanks TEX |
