OP amp replaced and so many caps were also replaced.
Quick bench check before going any further.
As expected, the sound quality in radio and cassette modes were not great but surprisingly, the CD mode was almost perfect.
You probably won’t be able to tell the difference compared to good unit.
Power I/F board also had serious damages.
The track was 95% gone.
As I was not happy with the sound quality in radio and cassette mode, discussed the matter with the owner and
we agreed on the significantly reduced cost and then decided to go for the display cleaning as well.
Can't do much for the deep scratch markings but still so much better now.
Before/After
In order to be sure of the operation, bench tested the unit for more than 15Hrs and then decided to install it on my NSX while working on another NSX.
Left it in cold weather overnight and then immediately went out for test driving session for more than 30min.
Came back, took some video for the owner and then put my head unit back into the car and took another video for the sound quality comparison.
Not perfect but at least, it can be used so it will be returned to the owner very soon.
Now back to another NSX service.
