The Howard Sams Company (In Indianapolis) publishes a a manual for
Model CS3125. It might be close enough to help you. Give them a call and discuss it. |

You shouldn't need a manual for a no-click problem. Follow the AC into
the chassis and you'll find a standby transformer either on the board of mounted to the floor of the cabinet. You can also work back by following the coil side of the relay back to it's DC source. Either way you'll check the transormer, rectifiers and filters that provide the 12 or 24 volts to the relay. Open primaries are not uncommon on these. John |

Thanks You likely will not find this manual in electronic form for free. It was only available in paper from Mitsubishi, so if anyone ever took the time to scan it, they probably did it to make a buck. I don't recall which on this set but there are only two likely sources. Either the stby supply runs off of an idling main switching regulator or has a traditional transformer and bridge rectifier. Tracing the ac line leads to one or the other or both. Look for the rectifiers. In either case, the ac or the switching signal has to be rectified. Before you spend too much time you might want to make sure that you have an ESR meter and learn how to find the leaky caps in these sets. Likely to find that it needs a fistfull. Google Mitsubishi and capacitors... Leonard |
