Pioneer VSX-808RDS IR problems (Was: Testing an I.R. Receiver)

[Mark Hennessy]

Functionally, there's nothing on the other boards - the signal just flows from the front to the back of the unit so it is available for the IR Out socket and can be interrupted by the IR In socket. The transistors are just there to invert the signal for whatever reason. However, plenty of contacts and solder joints to go bad

Following the signal from the receiver to the microprocessor with a 'scope is the easiest path. From the pictures in the service manual, it looks like this unit uses flat flexes so lifting individual wires won't be terribly practical.
