    Samsung Plasma PPM50M6HB power cycles

    Picked up this TV off of craigslist for $20.00. When you turn it on, the power supply would click on and off. Opened it up and found bad caps on the ysus and PS. Replaced all bad caps and checked all fuses to make sure they were good. Tried turning TV on and and measured VS VA voltages which were correct until TV shut back down.

    Unhooked the ysus and zsus one at a time and the power supply would still cycle on and off.

    Jumped the ctrl board and the PS, unhooked LVDS. Turned on the tv and the power supply did not cut back off but there were no test patterns on the TV.

    Looking for suggestions of what may be wrong or some other things I can check.

    Thanks

          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.

          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.

          Samsung Plasma PN43D450A2D No Power
          by CDNBrewer
          Hello, I have a Samsung Plasma TV - Model # PN43D450A2D

          This was my parents TV and the initial symptoms were that the display was hard to turn on with the display making various clicking noises until one day it would not turn on anymore.

          I took a look and found a couple 1000uF capacitors (i believe on the low voltage size) that had leaked out their electrolyte and did not test well on a tester. I replaced them but still no dice.

          When the TV is plugged in, there is no clicking, LED status lights (on PCB boards or the front display) and the power on button...

          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...

          Samsung Plasma TV Power Supply Issue
          by lp20th
          I have a vintage 2008 Samsung 50” Plasma TV, Model code PN50A550S1FXZA with a power supply part number BN44-00222A. I repaired the power supply board several years ago finding a couple of cold solder joints on the back side of the board and it's worked great up until now. Recently a fried sound occurred with the smell of burnt electronics and the TV shut down. Trying to turn it back on yielded the typical relay clicking with no TV boot up. Upon investigation, removing feeds to the other boards within the TV it was found that disconnecting the logic board from the power supply allowed the...
