Hi I'm currently working on a beogram 5500. I've cured a lot of problems but now I'm stuck. The middle of the 3 micro switches doesn't do anything. I have another 5500 to compare movement etc. I can here it click in and out but I'm unsure how to test it properly. plus I've had a look on the schematic but I've got totally lost as to what parts may need replacing if they are stopping the microswitch working. Any help appreciated.   Regards
