A BD235/237/239 is a closer match for max ratings. http://www.datasheetarchive.com/pdf/download.php?id=a26a26a4ec0c9a5e895602089d7faef1b8cf35&type=M&term=BD235 |

Even with a full schematic, the requirements for the main processor to keep the line relay closed and running is not obvious. Two of these cycles from O/I switch latches the unit off until line input power itself is cycled.(There is a dual flipflop in the housekeeping circuitry). All supply lines are monitored to develop 'power good', but there's no obvious power circuit failure evident during the period of relay closure - except that the front panel doesn't even blink. All service troubleshooting involves interaction with the front panel display. . . .with specialized harness extenders and board substitutions. The harnessing is nuts, with signals routed through 4 or 5 cards and connectors before arriving at their destination. I expect the organization of power circuits and control logic will be similarly convoluted. I've told the owner - no repair / no charge - take it to Yamaha service - but it hasn't been picked up since. RL |
