That's a lot of data, good job.
Not sure how you figured out no sound from what speakers, (did you just listen?). I really suggest you start by testing each speaker at the plug in the back of the radio to make sure 1) each speaker is wired and 2) and they are wired correctly. That has to be the start, than take it from there. Otherwise you are trying to hit a moving target. it is time consuming to do but worth it. Use the method I suggested in an earlier post on this thread. If you don't understand how to set up the 9V battery let me know and I will figure something out maybe a drawing.
