Thanks for all the good replies. The final fix was the 2 watt resistor in the regulator circuit R114U, it was open. I'm still stumped though for why the set played good for about 10 minutes when I first unplugged the yoke then plugged it in and had a good picture.

When I found out that the unit powers up with this connector unplugged, I reattached the connector and turned the unit back on and had a great picture for about 10 minutes. Now, it will only power up with the connector unplugged. By seeing a picture on this set I doubt that the yoke is the problem. I changed the 2.2mfd @ 200v cap in the yoke return circuit but it didn't help. Neil TV Doctors 108 W Main St Monroe,Wa 360-794-6469.........
