I am sure this is not your problem but it is amusing. I installed a Lyra Etna Lambda, a 9K cartridge. No sound. Tried everything. Nada. Then it occurred to me and my buddy that the VTA had been changed which changed the relationship between the pivot and the cueing lever. The curing lever was down and it sure looked like the stylus was in the groove but it was floating just above it. Re-adjusted the cueing lever and voila!
