    Re: Panasonic TH-42PX75U

    I believe the bridge rectifier is shorted on mine...the short over the 100 ohm resitor is apparently supposed to be there as from the schematic I found they actually call it a dummy resistor and both leads are connected to the same point, which I am not sure why.

        Bridge rectifier identification part number KPB305G
        by Steph.hen
        Hi all, a newby question about a bridge rectifier I'm trying to identify.

        I'm in the midst of reparing a battery charger in work which went pop, The bridge rectifier has shorted and took out a couple of other components. The rectifier in question has a part number KPB305G, and it looks like it's obsolete. Does any one know what I could replace it with?...

        Fujitsu Q556, What capacitor for bridge rectifier?
        by mpn78
        Hello

        My Fujitsu Esprimo Q556 motherboards blew up. At least fuse, bridge rectifier and capacitor got damaged. I have changed fuse and bridge rectifier (DF1508S), but I don't know what capacitor it is (picture). I know that capacitors size is 47nF, but I don't know other specs for it. Can you help me to choose right capacitor for my motherboard?
        There is 240V AC on input side of bridge rectifier and 340V DC as output on capasitors side.

        Thanks....

        Reading input and output of bridge rectifier on the same scope?
        by EasyGoing1
        I have a 40 volt AC transformer that I put a bridge rectifier on, and I wanted to see the input signal and the output signal on the same screen on my scope, so I set one channel up with the test lead on one side of the input and the ground lead on the other side of the input, then I used another channel on the scope and clipped the test lead on the positive side of the output then the ground on the negative side of the output.

        When I connected the transformer to power, the wire that was connected between the ground lead on the second channel and the negative side of the bridge rectifier...

        Diagnosing South Bridge (FH82H370) on Asus H370-Pro Gaming Motherboard
        by Ross Kohler
        Hi,

        I'm learning about motherboard repair and I believe I've traced the issue down for the South Bridge on the particular motherboard I'm working on. My path of concluding that:
        - There's no sign of any attempt to power on when pushing the power button.
        - No PSON signal is reaching the 24-pin ATX connector.
        - The Super IO chip is receiving the PS_SWITCH signal from the power button and is relaying this signal back to the South Bridge.
        - The Super IO is not receiving the S_SLPS#_R signal back from the South Bridge
        - If I pull the Super IO S_SLPS#_R pin...

        Panasonic TC-P55ST50 8 blinks then no blinks
        by Andre Gilbert
        Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
        Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
