Questions and answers
Hq sweet 16, just had it serviced, problem not resolved. It takes about 20min of operation before machine stops and the needle stays down. In about an hour the same thing happens again, appears to over heat. Before it stops theirs 2 pulses (noise) every 2sec for about a min.
back of machine clicks and shuts down & the needle goes down after about 40min. Just had the sweet sixteen serviced. I bought it used. The tech couldn't find the click because it takes about 40min to shut off the machine.
