    I'm working on a Zenith PVY5265DT projection TV (from 1997). It came
    in with QX3502 shorted and an open fuse in the power supply. I
    replaced the fuse, QX3502 and the HV splitter because it was drifting
    out of focus. Everything seemed normal for several days of running it
    all day. About a month later the set came back with the same problem.
    QX3502 is part of the HV regulator circuit.

    I know the later Zenith projections TVs are full of desing problems
    and common failures. Has anyone seen anything like this before?
