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

[Old Sparky]

I misquoted the Part No. of that 'supercap', Mark. I'd jotted it down on apiece of paper with a sketch of that circuit, and mis-remembered it. Comes with age I guess!! As for the effect of replacing C204, all I can say is that, yes I checked other voltages, and the Remote wasn't working anything before I fitted the new cap. The voltage on the +5v line was virtually zero, and, when checked the original C204 by applying 6v to it, the cap. wouldn't hold a charge, whereas the new one, after being charged for a short while by the same method, still had about 3.5 across it after about 22 hours.
