    I have a 14" JVC TV which I purchased new about 2 and a half years ago.
    Ever since I bought this TV, I've noticed a very strange problem with
    it. When the TV has been on for about a half hour or longer, it starts
    to give off an odor that is similar to a skunk or a latex glove. It's
    awful. It's only when the TV is on, not off. I thought over time, the
    smell would eventually disappear, but it doesn't seem to be...

    What could possibly be wrong? What could be causing the TV to smell
    like this?

    Thanks.

    Something is getting hot and burning. There could be numerous things,
    wiring, plastic after 2 1/2 years I would guess. Most liquids or
    spilled items would have dried up by now. You may want to have it
    looked at to avoid a premature melt down of something. I work on
    monitors and would advise you not to fiddle around inside unless you
    know what you are doing.

    An electrolytic capacitor is most likely over heating due to a failure. DO
    NOT use the set this way. Using it, may cause more damage, and also present
    a safety issue. Get it properly serviced!

    It could be High voltage discharge, this causes an ozone smell, this
    can occur from any high voltage point (20kv 30kv) especially if a
    connection has a sharp point or termination wire spike. If the back
    has vents, look through them in a darkened room and see if an arc is
    visible. Also underneath vents if possible.

    AFAIK, JVC had their chassis made by ONWA in 14' models. I was in fact
    working on an onwa chassis today, and noticed that the plastic plug for
    the degauss coil was hard up gainst the ptc thermistor and had melted
    and burned a bit. It was hard to separate them much, as they are so
    close together on the board anyway.

    There were also speaker cables with a plastic sleeve resting on power
    resistors in the power supply, but that only had a small slightly
    melted section.

    Typical low end junk design.

    I have posted a couple of pics :

    ....you may want to open your set and check that to see if you have
    the same problem!
