I guess, at this point, I should find more about your tools and experience. You stated that you were going to repair the digital odometer? Is that sort of work something you commonly do?
Do you have more than the most basic electronic repair tools (more than soldering iron and meter)?
Do you have a ready access to electronic replacement parts?

I have very few tools and parts as most have been thrown away or passed along to other people. I did a lot of circuit work when I was a kid late 1970s through 80's but not so much lately. Occasionally I can take a component apart change a driver transistor or a swollen capacitor and have it working but that's really the limit to my ability.
The digital odometer according to multiple forum posts is a seating problem on a small board containing a primitive non-volatile RAM IC. If it's not, then I probably can't fix it or I end up resetting the mileage to something meaningless with a replacement component.
I cannot find the exact replacement amplifier for sale at the moment, but there are dozens available for a slightly newer vintage that I think I can adapt by cutting the connectors off of my broken one. The unknown is whether the input levels are similar.
No.
Nothing at hand, but the parts tend to be cheap via mail order.
I think what you are implying is that fixing it may require changing parts randomly. I'm happy to give up on this one and move along since it is obviously not an easy fix for me.
Again, it's up to you. I don't mind trying to help but it will be in a generic manner. I understand the components but not the circuit.
If removing the module is not difficult for you, remove the other module to see if it will power up.
