Connex 3400HP/Talkback on all the time

Good morning
I have a Connex 3400hp that has had some issues, most have been fixed .
the only one that's being a pain is the talk back.
the owner of the radio said the talk back was always on and he sent to a shop to have it checked out.
this shop could not figure it out and installed a separate talk back.(relay installed with power off the TP-8 rail with cap in line, also TX power off of L-38,J-3 was removed and jumped over to the relay).
This has all been removed, also the power/ TB pot was shorted (replaced ).
Still have full talk back with no control from power/TB pot.
Has anyone had this issue and maybe give a little help.

Thank you

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
