Hi Phil, I had a reply from Wayne Vanaman that you may have read. In it he said that he has replaced the pll ic in the tuner for this symptom. It is a flat pack U17501 P/N 231529. Is this possibly be the same IC you are referring to, only with a different location number. Would you happen to have the P/N for the IC you changed?

Lifting the Vcc pin allowed it to power on (without tuning). U17701 ( uhf-vhf-mixer-osc) pin 8 is Vcc. Phil Bader Paul wrote: > > This is definitely not my day.
