    Thanks for the info. Work in a electronics lab; oils from us can cross
    onto the cards and accelerate dust collection, more heat generated, bad …
    Power tools, if for task in electronics, will be torque calibrated to not
    strip out screws or screw wells.

    Why to do repair people feel the need to use power screw drivers ? Why not
    take the time to use a conventional screw driver and NOT damage the screws
    ? Please throw away the instrument of destruction , thank you. O__ don`t
    work on my TV !!!!

    Unbelievably easy, this is the $400.00 repair I was quoted? I’m sourcing a
    new board today. Thanks

    Is the “main board” the same thing as a “signal Input Board”?

  7. Ozzyzzo76 says:

    a main board problem can also create audio problems, power supply PS_ON
    problems, and INV_ON problems.

    Nice job. Currently replacing my mainboard for audio problems. No audio
    from speakers nor output unless rca stereo.

  9. Ozzyzzo76 says:

    why are you wearing gloves….this is not a murder?

    If you get the correct part there is no aligment on lcd tv.

    Interesting how many “Samsung” digital TV repair videos “clutter” youtube!?
    After the 61″ DLP set I bought in 2005, and all its problems, and now our
    32″ LCD with main board issues… I’ve pretty much had it with Samsung. I
    pray my small flat screen tv-monitor doesn’t have issues. Many techs lament
    the Japanese-Korean competition to build the “cheapest sets”, as it’s
    greatly reduced quality. Since when should a TV die in the first 3 years…
    ? Technology comes with a price.

    dont forget to wear booties

  13. Ozzyzzo76 says:

    Samsung recommends that all service techs wear gloves on hands and booties
    on feet. All Samsung techs must be background, and drug screened.
