    Re: Why is this display dim and whining?

    I see it, not sure how to interpret it though.....

    The majority of the pins on the regulator measure 12V, there's a trace from the lower right pad to a diode, the other side of the diode measures ~30V.

    Interestingly enough, on the good board that diode measures 38V.

    Look for the glob of solder to see where I'm talking about, the corrosion broke the trace so I did the best I could with one hand....
