    Panasonic SA-BT203 Power Switch Clicking Won't Turn On Issue

    Hi guys I have a Panasonic blue-ray disc player Surround Sound that is giving me a lot of headache trying to repair. When i press the Power button it gives a Click Click sound but doesn't turn on.I checked Power Supply Board for swollen or bad ESR caps with my ESR Meter and all i found was some swollen caps on the Audio Board i changed with new caps but still the same. Checked the whole board for shorts and there isn't any.I used to have like 3.3v on the Power Switch Button but now i have 20v ... Is that normal? isn't it supposed to be 3.3v on the Power Switch? I am hoping you guys might be able to tell me what IC is supposed to actually break down that voltage from 20v down to 3v.. Is it just a Resistor ?
    There is a website that sells parts for this unit. So i would of liked to determine which part is actually bad so i can order that particular part instead of buying the whole lot of parts for it.

      Dell AL440LX power on switch circuit help required
      by Powderfanupnorf
      Hi Everyone. First official post so fingers crossed I conform and also manage to get photos to work.

      So I am requesting some help from anyone who happens to have one of these motherboards to hand and perhaps a multimeter.

      My board has a single row of header pins for all the front panel stuff (have seen others where they are grouped together differently so thats no help) and the two pins for the power on switch had been previously repaired and I am trying to make a better repair. There looks to be pad and trace damage and im happy to relocate the header pin/pins to...

      Acer Spin 1 SP111-33 Power-On Issue (Troubleshooting Assistance)
      by justice171
      I am seeking guidance on an Acer Spin 1 SP111-33 that does not turn on when pressing the power button.

      Below are the observations and troubleshooting steps I have taken so far: Observations and Tests:
      1. Verified that all critical voltages are present:
        • 3.3V and 5V are always present if DC is plugged.
        • 1.8V on the BIOS chip is present.
      2. Checked the power button functionality:
        • When pressed, the voltage drops to 0V, indicating the button is functional.
      3. Inspected the flex cable connecting the USB, audio, and power button to JUB1:
        • Confirmed connectivity is intact, ruling out issues

      NEC TurboExpress On/Off Power Switch Replacement Help
      by grimacelord
      Hello,

      I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.

      I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.

      I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need....

      Sony SLV-E780 Power Supply Issue – Clicking Sound, Need Help Identifying Faulty Component
      by Akuanka
      Hi everyone,

      I'm troubleshooting a power supply issue with a Sony SLV-E780 VCR. The device clicks repeatedly but doesn't power up completely. I've already replaced five capacitors, but the problem persists.

      Here's a video link https://photos.app.goo.gl/3Xki6yvCLn67gLX78​ showcasing the sound. Based on your experience, could this be due to a transformer, diode, or another component? Any guidance on what to test or replace next would be greatly appreciated.

      Thanks in advance for your help!
