I'm worryed about blowing IC-601 but am good if I have to get another if I can find the short. The resistor R-607 is good and if I fire the board I get the 341volts to the filter caps but it doesn't get to the CN641 connector and this is with the supply out. I can wire up a 5k resistor to pins 10 and 11 of CN-641 and it will trip the relay but I still get no B+ to CN-641. To be honest I don't think I'm getting 9 volts or the AU voltage either.

Edit : When I 1st started with this set the TV worked but was getting squish horizontally so I took the power supply out and did a visual inspection and found nothing fried and no blown up caps so I put it back in and that's when it wouldn't fire up again but I didn't do anything to the main board at that time.

Do you think the power supply will work right as a standalone if I trip the relay. If I can't get B+ to CN-641 there is no need to put it back in the set unless there is maybe a pulse that sends voltage back from the flyback. Just wondering ?
