I have been thinking about your radio all night now.
I have not worked on this radio for years but some items are coming back.
this radio is controlled by the cpu on the front of the radio. should have a metal shield on the cpu covering it up, could be getting this mixed up with another radio. but look at the bottom of the cpu and there should be 2 resisters side by side and they are prone tro go bad. they will look burned or just crusty looking. it they have gone bad can cause the same problem you are having. look close and if the are bad you need to change them out. I have just changed them out in the past when working on this type of problem. i think one is a 100 ohm and the other about a 82 ohm. change them out and see if it takes care of the problem.
