    Do you know how to use a multimeter or osciloscope if you have access to one?

    Many such issues relate to dried-out capacitors - often identified by a 'bulge' in the top of the case of the capacitor - so a readily-identifiable issue. Post a picture of the insides and it may be easy to spot the problem.

    Of course other problems may be present but we tend to go for the obvious first!

    It should be in the service manual. If not try "google.com".

    If you have the skill to measure while the audio system is running (do this at your own risk), you need to check the output of the power supply and the amp. If the output is correct, than these 2 modules are ok.
