    Samsung LE37R88BD Bad T-con? picture lagging ghosting

    Just thought I'd quickly write this one up!

    T-con - T370XW02 V5 CB 06A69-1A
    Main - BN41-00813B-MP1.0
    PSU - BN44-00157A (PSLF231501A)
    Invertor bd - 4H.V1448.481/C1

    Ghosting, laggy, colour distortion, dark picture

    Vgama readings from T-con:
    1 - 15.4v
    2 - 15.27v
    3 - 13.49v
    4 - 12.3v
    5 - 11.45v
    6 - 10.84v
    7 - 10.84v
    8 - 10.18v
    9 - 9.92v
    10 - 7.53v
    11 - 7.34v
    12 - 6.84v
    13 - 6.94v
    14 - 8.13v
    15 - 8.29v
    16 - 8.48v
    17 - 8.71v
    18 - 9.01v
    19 - 9.31v
    20 - 9.75v
    21 - 11.10v
    22 - 11.15v

    Not quite sure if these readings confirm its the AS15-F thats faulty on the T-con but they are similar readings to another thread where the AS15 was recommended to be replaced but no outcome was posted so not fully conclusive unfortunately.

    Could someone please confirm.

    A few caps were replaced on the PSU, 2 x 1000uf, 1 x 820uf and a 470uf as they were beginning to bulge.

    If confirmed I shall order a couple of AS15-F's and see how I get on replacing it with heat pad and heat gun though I need to practise more with these tools.

    Thanks guys!

    Yes, those readings are off. When you write heat gun do you mean a hot air station or something for stripping paint ?
    If you've not done one before the easiest way would be to use some chipquik and an iron.
    The AS15-F is sensitive to heat

      Yes sorry, hot air station!

      I also now see that the readings are off!, from about Vgama13.

        That's ok, I was just checking, 6 and 7 shouldn't be the same either.
