Issue with sansui 9090db

Good Day AK Members,

Working on a Sansui 9090DB. It is a nice unit, however I have a problem.
This unit has a F-2654 Push Switch Circuit Board and a F-2655 Dolby NR Circuit Board.

Two screened cables (one is yellow, the other one is red) are connected to the approx. center location pins of the METER / REC CAL TONE push-button switch. Please see second picture. Each cable is connected to a different pin on the push-button switch. No issue at this end of the cables.

However, both cables at their other ends need to be connected to the F – 2655 Dolby NR Circuit Board.

Here is the issue. While the red cable is still connected to the F – 2655 Dolby NR Circuit Board as can be seen in the third and fourth pictures, the yellow cable is detached.

The yellow cable is shown with its loose end in several pictures. It might connect to the copper side of the F – 2655 as suggested in picture four or it might need to be connected to the components side of the F – 2655 as suggested in the fifth picture.

I am looking for the connection point of the loose end of the screened yellow cable on the F – 2655 Dolby NR Circuit Board.

Any help will be appreciated.

it's late here and I'm under the gun to go have dinner but if you don't get an answer from someone else I'll pull the tuner tray and take a look hopefully tonight but maybe tomorrow morning. Either way you'll get an answer...

You only have to pull the bottom cover to find this one.:D

Thank you very much Rob.

So it is not going to the F - 2655 as I thought initially!

Thanks again for taking time to respond and providing great pictures.
Most helpful.

Will solder it now and let you know the outcome.
 
Good Day Rob,

Soldered the yellow cable to the right location!

All back to normal now.
Now the 9090DB sings again!

Thanks again for your fast and clear help.
