    Sceptre X37SV-KOMODO bad repair

    We receive this TV for recycle today, we were told that the TV was repair by DIY but could not get it to work, the Blue power LED is still blinking.
    I open it up to see what is needed to be done to fix it.
    The one cap in the 24vdc power supply was replaced by 3 general purpose 85c caps in parallel (470 + 100 + 100).
    I put in 1000uF 25V Panasonic FM in its place, the TV starts right up, then I wne ahead and replace the set of caps.

    sad that they didnt bother to spend the 2$ for a decent cap after they spent the time to dismantle the tv. Good for you though

      Does demonstrate why general purpose caps are -not- suitable, even temporarily.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

        Wait, the ghetto 'cap' was where that blank spot for a capacitor is? Do you think the original was a rubycon? There are two other rubycons near that blank spot.

          The blank spot was where I removed that DIY cap from. The TV is now going to be donated to the senior center.

              I know this post is old, but the behavior described is similar to my issue. It isn't clear where the 1000uF 25V Panasonic FM belongs on the power board as there is no before/after. I am not sure if it is my issue, but I want to be sure of what I am looking for before I open up the tv. Any help would be greatly appreciated.
