    Samsung PS50B850Y1W No power just clicking

    Hi All

    Been a long time since i had a plasma and just my luck one iv never seen before

    PS50B850Y1W Just clicking

    Va and VS come up briefly while its constantly clicking

    I have tried disconnecting YSUS then XSUS but still the same

    Both Y board and X board do not have short to ground on either VA or VS

    On the powerboard and i noticed it had some damage to the fan wire(been cut), not trusting this board iv tried a replacment but its still the same.

    Can anyone help me with jumping the power supply on so i can rule the mainboard out ?

    Also any oter checks i can do ?

    PS - BN44-00277a
    Main - BN94-02826c

    Regards

      Jumped PS-on to GND and the power supply all came up with correct volatages and all boards plugged in = Mainboard ordered

          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
          by Tynan Dill
          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

          Upon bringing it home and plugging it up, it showed a standby light.

          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

          The screen seems to blackout and stay black, but with a flashlight I can see the display.

          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

          Assuming...

          Microsoft Surface Pro (5th gen) model 1796 - no power
          by PantherDave
          Hi all!

          I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

          I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

          Asus Probook P5440UF-XB74 power issue
          by GLISIT
          Hi all,

          TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


          I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

          A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

          Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
          by JimBanville
          The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
          Opened it up and discovered the power supply is making a faint clicking or ticking sound.
          I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
          I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...

          Samsung UN43NU6950FXZA No power
          by mrtek
          Hi

          Picked up another TV. Samsung UN43NU6950FXZA. No power and no standBy led on. Removed back cover and:
          Main fuse = OK
          Back light LED = OK. Power them with aux power source
          LED output = OK 156V
          I do get 12 V DC out of the power supply going to the digital section but no 5V or 3.3V. PS_on voltage is only 1.8V. I have looked everywhere on the PCB , I could not find i reference for 5V output.
          Also removed connections to panel, speakers and remote but no luck. One strange thing is that even with the LED power supply working, backlight LED do not turn on...
