Q14802! I kept going back to diode CR14800 , which is a known suspect part. It was good, but in circuit it measured a very low resistance across it. Even cathode to ground was almost short. After lifting jumpers all across the board starting at Cathode CR14800, I finally landed the trouble: Shorted transistor Q14802 (TIP122) located on a heat sink near the front of the chassis. Replacement of Q14802 fixed the trouble. I also pulled and checked all scan caps, and the 6.8 mfd BP lytic C14805. Only fault was transistor.
