    Can anyone help?

    I have a 5inch LCD tv. When I first turn on the tv, the image
    jump/jutters up and
    down for about 3-5 mins before leveling out.

    Does this sound fixable or is it a write off?

    Thanks

    Most likely some component(s) has become thermo sensitive. Eventually, it
    will most likely fail. Depending on the type of component, it may have to be
    sent to the authorized factory service rep to have the service done.

    An experienced tech should be able to find the thermo sensitive component
    using freeze spray and a heat gun. If the part is non-generic, he may not be
    able to buy it from his main supplier. He would have to get the original
    factory part.

    In many cases, I have had defective capacitors cause this type of fault in
    various units. Most of the caps used in these monitors can be generically
    purchased. Most of the parts are surface mount types, and usually require
    the proper soldering station to be changed.

    Thank you very much, thats very helpful to me.

    Im quite electronically minded myself. Though I don't know much about
    what these componants are for, I know a bit about how to find the
    correct replacement parts. Unfortunately, there are only 3 of these
    products ever shipped to the UK.

    Is there anything I can do to detect a blown cap? I have briefly looked
    inside to see if any of the caps have popped, but didn't see anything.
    Does this mean I need to take it to a specialist?

    Thanks

    Sometimes they'll bulge or leak, otherwise you need to check them with
    an ESR meter.
