    Hi guys; please can you tell me if Diode 31DQ 06 Shchottky measurements
    are right for this Tv Power Supply

    Forward Bias 0.217

    This is a Sumsung Monitor 2493 HM blue steady light on and no black screen,no 24v or 5.3v to the boards invert-er and main board no visible bad components,i checked all components that i could with my Fluke 84 and do not find anything out of specks except suspect this Diode 31DQ 06 Shchottky measurements,any help would be apreciated,thanks in advance

    The Vf stated is somewhere near right or maybe just a little high.

    Note that most SB rectifiers show measurable reverse leakage on a DMM resistance range.

    Its rated 3A, the 06 means its 60V - about as high as they go before prices rocket.
