[Jukebox-list] HF100R Mech Issue

I Have a customer with a 100R that keeps getting stuck on K9 playing over and over again. I was there yesterday for the second time and made a very slight adjustment on the contact block to insure the cancel coil was resetting the pin.

Then I selected A1 to observe the pin cancel (which it did) then K9 again and the pin was cancelled.

I repeated this test process 3 times and each time the mech functioned accordingly.

I left thinking all good. This morning a text from him again saying mech stuck on K9.

Thankfully he is only 30 minutes away but it's getting old. Any thoughts on what to do or what else to check?

I think I had a similar issue years ago but I don't remember what the resolution was.

Regards, Rick
