Yes, C916 tested good.  Sorry I didn't mention that obvious solution.

This 35" set comes on with HV for a split second and then goes off.  I
brought just the chassis back to my shop and replaced C940 which had
high ESR.  I then powered up the chassis with the HOT removed and my B+
went up to about 145 volts before it went into shutdown again.  I am
thinking the B+ is going too high, causing the shutdown.   I am
suspicious of the regulator IC901 STRS5141G, but I need to know what the
proper B+ is for this set.  Thanks.
