    Samsung BN44-00878A Power Supply Removal

    Hello All,

    Thanks for assisting, I made sure to check the forums first before posting and was unable to find any answers. Hopefully I didn't miss something.

    I have a Samsung UN55KS8000FXZA that has the Samsung BN44-00878A Power Supply board. I have looked everywhere and have been unable to find any idea on how to remove the board from the frame.

    The board itself has no screws in it, only small "lock" holes with white arrows on then (in the picture there is nothing in the holes) and what look to be aluminium tabs, but when I was trying to slide the tabs and remove the board, the board itself started to bow. It feels pretty darn stuck, is this board glued in?

    I don't want to damage the board, in case the replacement board goes out and I need it. Can anyone tell me how to remove this board?

      I believe there are two screws in the power inlet, did you remove them? attach a picture

          make sure there are no screws as suggested. lift slightly on the board with a finger where it says lock and shift board in the opposite direction of the lock. Usually to the left I think.

              To the right when the power supply is on the right side after opening the TV.

              @SomeoneLooking4Help, keep in mind to discharge the power supply before you touch the primairy part of the power supply.

                  I removed those when I was first attempting to dislodge the board (before cutting the infamous JP854) and it wouldn't budge. I was only pulling up on the board though, not moving the locks out like suggested so I can try that.

                      To the left sounds about right, I did remove the screws and still found ti to be pretty well secured but I didn't try pushing it to the side. I can try that next.

                          If you go to shopjimmy you can have a look at the board when it is removed, If I remember It slides to the right to be removed.

                              Thanks William, I will definitely try this. I also have my field service kit ground wire attached but I will discharge before I try removing it again.

                                  I did check out the shopjimmy pics but it only shows the board removed but so far everyone has given me some great info to try. I Will get the new board on Friday and will update you all, thanks!

                                      I recall it slides out opposite to the directional arrow (for installation). Clips by the AC plug could pop out but are easily reinserted.

                                          Hello and thank you, thank you to everyone in fact. I was able to remove the power plug screws and then gently lift the "lock" areas up, which allowed me to slide the entire board to the left and remove it.

                                          After replacing the whole board, I am STILL having the issue with the flickering. I don't know what else to do, perhaps replacing the main board? I will open a different post, as this is now a totally different issue.

                                          The TV i 2 years old, just old enough to be out of warranty and just young enough to not need to be replaced.

                                          Thank you all for your assistance!

                                              Try turning the backlights down NOT brightness, see if there's any change.

                                                  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.

                                                  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...

                                                  I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

                                                  This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

                                                  by repair-it
                                                  I am attempting to test a samsung power supply board to verify the pfc ic is working. I am powering up the board with my isolation transformer. The board turns on fine but when I attempt to connect the ground for the scope probe, it trips out the isolator. I was taught not to 'float my scope' so I am wondering if I should test without connecting the ground lead or would that be asking for trouble? Not sure how else to test, I don't have a portable scope. I could plug direct to mains power but that would bypass the safety factor.
