    I have a Toshiba 32AF42 that is working strangely. Occassionaly, any
    station on the highband channels (6-11) look like they are getting
    corrupted by electrical noise (enough so the picture is almost blurred
    out) or, sometime the picture looks like the tuner cant quite lock on to
    the signal (actually the picture reminds me of how older TVs displays
    looked when the AGC was greatly overdriven. In the 'cant lock on to
    signal mode,' there is a noticeable hum bar that moves up the screen at
    about 8-10 Hz. There is nothing in the house that is producing
    electrical noise or a RF interference. Any clues as to what may be dying
    in the set?
    Also, is there a way to reset the processor on the board? Perhaps this
    might help. Other suggestions appreciated.

    If I had to guess, I'd say cracked solder joints in the tuner,
    especially if the problem comes and goes randomly.
