    Samsung pn58c550g1f

    I need help with the power board for this plasma. The board is BN44-00331A.
    I'm very new at tinkering with boards. I inspected the board and found a blown fuse. I replaced the fused and plugged the tv in only to hear and see a spark. Upon close inspection I noticed this ceramic capacitor had cracked(11 year old TV). I believe it's a thermistor. I would like to replace that component but have no idea what to replace it with. The only boards I find online are all used and cost at least $100. I figure my board is just as old, why not just replace this one component. I think I've attached the specs to this component. Again I have no idea.

      You have identified it correctly but there will be more damage: the NTC can not blow the fuse because it is in series with the live (phase) wire.
      So probably there is a shorted bridge rectifier or something else on the primary side of the PSU.
      You will need a multimeter to check resistance to identify which component it is that is dead.

          Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
          by ohren
          I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

          I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

          The models launched in 2018 and 2019 respectively....

          HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
          by m1ch43lzm
          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
          Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

          Samsung Power Supply Board BN44-00874F
          by Nicktronic
          Hey everyone,

          This power supply board is hard to find but there are repair kits available. This board had a blown fuse, FP801S, blown PFC MOSFET, QP802CS and ceramic cap, CP809. I replaced them with parts I already had and tested the rest of the parts that would've come in the repair kit and they were fine. I powered the board up on the bench expecting, in typical Samsung power supply board fashion, to see all my output voltages but, nothing. 0 volts on CNL801, CNM801 and CNT801. The only thing I have is 170vdc on the filter caps. No standby voltage either.

          Anybody...

          Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
          by Asraf Atb
          Hi everyone,

          Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

          Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

          I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....
