The "puck" that sits on your desk is its own mini-computer. It handles the digital decoding (Dolby Digital and DTS) and the matrix upmixing. The service manual will often include the for the ribbon cable connecting the console to the sub. This is vital because that ribbon cable is a known weak point.
If the system is completely dead (no lights on the console), the issue is usually located in the Subwoofer Power Supply (PSU) Board Blown Fuse:
The "Digital" light blinks, but no audio passes through. Service Manual Diagnosis: The manual points to the CS8416-CZZ digital audio receiver IC on the main DSP board. You are instructed to check the crystal oscillator (Y1 – 12.288MHz) and the voltage on pin 20 (VD+). If these are fine, the issue is often a failed logic gate on the input switching circuit.
