    Hi Sai,

    Thanks for your response. We do not have a glow and can not see anything with the flashlight either.

  • meagan1430 Feb 07, 2010

    No, we do not see anything. Usually the big white "W" comes on before anything and this does not even come up.

  • meagan1430 Feb 07, 2010

    No, we did not see the big white "w" that we usually see either

The picture but no sound on LCDs is usually due to
1)Faulty Inverter board/Backlight
2)Faulty Video driver board also called T-con or timing control board

Turn on the tv and darken the room. See if you can notice a dull glow on the screen. If there is then the inverter board is functional and you have a faulty t-con board
If you don't see any glow then then take a flashlight and flash it on the screen and see if you notice a faint image. Keep flipping the channels to make it more noticeable.

Let me know your findings,

    Do you see a split second flash on the display as soon as you turn on the tv?

    Ok.. This is where it gets complicated. As the fault can be in one or more of the four boards.
    1)Main Video board
    2)T-Con board
    3)Backlight inverter board
    4)Power board

    Do you have any prior experience in fixing electronics? Soldering, Using a meter(If required) etc.,

    Then I think it is probably better for you to get it checked by a tv tech. I sure do not want to take a shot in the dark by telling you that replacing some board would resolve the issue even though I think its probably the inverter and t-con board that need to be replaced(Both of them usually cost under 150$ together). However I do think a component level repair might be possible if its the main video board or the powerboard as its usually failed caps that cause this problem. Please provide me your zip code so that I can guide you to a local repair tech.

    Westing house has a warranty of 2 years(without purchasing the extended warranty) on most of their products. If your tv is under two years old then you are most likely to get it fixed for free. Anyways here is the listing from our repair directory just in case
