BX645A - follow up (Techniek Radio/TV)

Dear Mr. Rajan,
This looks like a Sk7 failure ,short circuit.
It should open in a rather smal sector of each revolution of the outgoing motorshaft
in order to position the contacts of Sk6 , well in between open and closed. With all
bandswitches released ,stop should occur after each manual repositioning of the motorknob.
Turning the motorknob by hand with power to motor only should reveal the open sector,
if not,Sk7 has a sticking contact and will need open hart surgery,
Best wishes ,
Sieme
