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

[Old Sparky]

I've tested the receiver - out of circuit, with a DC supply from AA Cells, with the'scope probe connected between the ground and o/p pins, and am seeing very little on the screen , so, Trev, you may be right Now to open the R/C and check those resonators. Come to think of it, I've occasionally changed them in the past.
