Wharfedale TV power problems

32 inch Wharfedale LCD TV bought from argos keeps switching itself off arbitarily while in use. Problems started on the 13th month of purchase. TV now permanently on standby. PLEASE HEEELLLP!!! Same problem with my Wharfedale purchased just over a year ago and had initial problems with it switching off and not being able to turn it back on. Sent it back for repair and it has been fairly reliable for a year but in the last week or so has started to switch itself off consistently every five minutes. Have consulted a TV repair place and they mentioned 'dry' somethings might be the cause but said it would cost £70-90 but they may not be able to fix it. Surely if other people are having the same problem the manufacturers must be responsible.

    • A low voltage power transformer feeding one or more sets of rectifiers,
      filter capacitors, and possibly regulators.

      A power surge could cause the primary of the transformer to open up.
      There may also be a thermal fuse under the outer layers of insulation
      which blew either due to overheating or a power surge. However, if the
      primary is open, it is best to replace the transformer rather than
      attempting repair it.

    • One or more voltage dividers connected directly to the AC line feeding
      rectifiers, filter capacitors, and possibly regulators.

      Open resistors and dried up capacitors are common failures since the
      resistors are often not rated adequately and run hot, in close proximity
      to the capacitors.

    • A portion of the main (switchmode) power supply that runs all the time.

      Failures could be almost anything that would affect normal operation of
      the power supply as well as problems with the control circuitry.

    If there is a low voltage regulator or separate switching supply, it
    could be cycling on and off if the horizontal output, flyback, or
    one of its secondary loads were defective.

    Does this TV have a separate low voltage regulator and/or switching power
    supply or is it all part of the flyback circuit?

    Verify that the main filter capacitor is doing its job. Excessive ripple
    on the rectified line voltage bus can cause various forms of shutdown
    behavior. An easy test is to jumper across the capacitor with one of
    at least equal voltage rating and similar capacitance (make connections
    with power off!).

    Use a Variac, if possible, to bring up the input voltage slowly and see if
    the TV works at any point without shutting down. If it does, this could be
    an indication of X-ray protection circuit kicking in, though this will
    usually latch and keep the set shut off if excessive HV were detected.

I would not keep a new LCD TV that has immediate problems. I would get a refund and purchase a more standard brand television. Experience has taught me that if one has problems immediately with an LCD TV itself, it is likely to continue to be problematic.

Thank you for using FixYa.

Sharp TV switches to "input 2"

Mine does the exact same thing. I've had it for a few years no, and it just started doing this. It's so annoying. I don't think the weather has anything to do with it, though. It started switching itself just every once in a while, not it is almost every time I turn it on. Sometimes it takes an hour or so to start doing this, other times it's right away. Help!!
