Peter,
First off, I will assume that it was working at one time.? Since the issue started have you tried CW?? Also, I noted that you have power on 40 meters.? Is it above 7 watts?
If you truly have power on 40 meters and not on any other band then I would look at the LPF relays to verify that they are working.
Just some suggestions and questions.
