Got this one in today, the AC adapter will shut down when plug into the DC jack on the monitor. The resistance between the + and - pin on the DC jack shows < 1 Ohm, remove the INDUCTOR that is connected between the + and the power MOSFET, the MLCC but the short is still there. I remove the solid cap then the shorts went away. I am surprised that it has this solid cap at the DC input jack but not at the outputs of the switching power supplies on the board. I install the PANASONIC FM in place in stead and check to see any ripple at the DC jack with the scope, nothing there to be concerned about. I will be burning in for about a week.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]
