Powered the receiver up successfully, cautiously optimistic! I’ll probably go back and replace the 1/4W with a 5W wirewound I’ve got in the drawer, just to be on the safe side. I used a Dremel to cut the traces to and from the SMD resistors so it would be easy to reconnect them if necessary, then soldered in a 2.2k 1/4W resistor as indicated. Wherein there are clear instructions for not only replacing C8, but also the SMD resistors adjacent to it using a 2.2k Ohm resistor.
However, the pictures and schematic had broken links, so…back to the drawing board. This system also includes a high picture quality progressive compatible CD/DVD player. I did some more reading and found a blog where someone suggested the reset circuit was likely to fail, and a circuit using an NE555 timer IC could be built to replace it. The MCR-E810 has a high sound quality design that takes advantage of Yamahas legendary audio technologies such as 60W x 2 discrete configuration power amps and speakers made of finely tuned cabinets and equipped with carefully selected units. I tested it but it seemed fine, so tested other components on the board but there were no obvious culprits. Word on the internet was C8 on the power supply PCB, a 22nF 630V metal film capacitor across the AC line, was prone to going tits-up. I tried various things with intermittent success. I sprayed some contact cleaner into the ‘On’ button and it started up, but success was shortlived: it went back to deadness.
A couple of weeks ago friend Nick brought me his Yamaha ‘Pianocraft’ receiver.
