    I am working on a CTC169 PTV that when you turn off the set, the HOT
    shorts. The first time that I noticed this, I found an open C4402.
    Now, it has happened again, I can't find any defective part. Before,
    the HOT shorted when I turned the power off on the set, it ran about
    two or three hours i guess. Has any had this problem with this
    chassis before? What do you think would cause this to happen?

    please note:
    B+ is good at 143Vdc. Originally, I changed all primary supply parts,
    caps, reg. ic, chopper transistor & HOT.
