Lindbergh cabinet : ampli sound board CN3 wiring/utility / needs wiring infos for test and service button

[mr_magooz]

Hi
i just bought a lindbergh cabinet. But some problems with test and service switch which are not wired.
It misses the connector under the board (where are the service and test button)
also i found some cables cut from the jvs io board regarding them (the service and test button).
They have been connected to a strange connector on amplifier sound board on CN3 .

How can send me some pics about wires between the service and test button from the board to jvs io board pls.
And when i read the manual of lindbergh, there s no infos about the role of CN3 connector on amplifier sound board.

Thx

That's the wiring for the volume pot.

Test and service buttons are connected to the 60-pin digital input connector on the JVS IO. Check the schematic.

Are you sure it's CN3? Normally nothing is connected to CN3 (the 6-pin connector).

The volume pot is wired to the 3-pin connector next to it, CN2.

I confirm test and service are hooked to CN3. I don t know why but done like this
I found this because when i put my TTX2 plugged it launches test mode and when i enter input test i can see service button and test button always pushed.
