Cobra 25lTD no transmit/receive

I was given a cobra 25ltd nice clean condition but 1 problem.

There is no trans/receive.
Tried different mic
Led turns red when mic keyed
no meter movement.
Audio chip ok pa works.
Is there 1 part that would kill both trans/receive at the same time.
I have the voltage chart and gonna do some testing.

Did some voltage checks at the pll and all seem to be correct,

any help appreciated.
