Effect of high household voltage on TV?

  1. I have a 32" Toshiba TV. Today I had problems with my
    household electrical current; apparently a bad neutral
    connection resulting in probably 160 volts or so in one wire
    and 60 volts or so in the other. The TV appears now appears
    totally dead (except for a small light next to the power
    switch (apparently indicating power is on). Assuming these
    voltage variations caused the TV's problems (it was working
    fine before). what are the possibilities of what it likely
    damaged--and a rough idea of repair costs? (I am wondering if
    I should take it to a repair shop or just get a new one--model
    is CE32H15, 5 years old or so}

    Thank you.
  2. If you like the way the TV was working before it died, get
    an estimate. It may not be that bad. Conceivably just a
    blown fuse or other simple problem.

    Tell them what happened. If it was off at the time of the
    incident, probably in the pwoer supply. If on, might also
    or be in deflection.

    Also, if your supply voltage in your residence is varying that much you will
    see more damage to electrical devices in the future. Have an electrician
    checkout your supply to determine just why there is such a variance. May
    also get your local electrical supply company to come out and check their
    feed to your residence, in case there is a problem in their drop or
    transformer. Not only is there a probable chance of damage to your
    equipment, it is also a safety issue since this can be condusive to wire
    related household fires.

    I'm no electronics whiz, but when this happened to mine during a lightening
    storm it blew a small capacitor/resistor in the back of the TV which was
    acting like a fuse. Cost $15.00 to have repaired.
