I received my first Sansui G-5700 in the mail today. I bought it to repair and restore as my main receiver. It is not as good cosmetically as I thought; but sometimes that happens with poor pictures and ordering online. After I got it I was thinking I should have paid less... I will have to find some new aluminum looking film for the face sides eventually. Good thing is it is in very good shape on the inside, just dirty and the patented puffed C612. The radio stations display fine, the signal meter works fine, but the Tune center dot never lights up, nor the red stereo LED. There is no sound of any kind, and the power supply relay does not click. Oh and the string/pointer is off compared to the quartz display numbers, but the string can be adjusted. I have decided after researching on here, the best thing is to restore the power supply board almost completely. The service manual seems to be lacking on the resistor list with the boards, and I will have to go into the schematic to get the values and maybe even the original resistors themselves. First I will do the F-2980, then the F-3000, and so on. Could the MSM5540RS Chip be causing the tune and stereo LED issue? Any recommendations would be appreciated!
