Intermittent data input issue


Mike Eccles
 

I have a K3, serial no. 4315, that has started showing a data input problem. All looks OK but sometimes audio data on the data input BNC connector is not being detected. Microphone input is always OK. A hefty “thump” on the case usually fixes the problem!

Could this be a sign of internal board connector/pins intermittent contact? Has anyone else seen this type of issue on an older K3? Anything I should be looking for when I remove the case?

Any help would be much appreciated.
