    Re: Samsung 50" TV flashing power light

    let's see if this get's the ball rolling. The 6270 has the same PSU, the main is different but potentially the same pin outs, maybe the flow charts will help too

        You know, so far we still do not see the pictures of YOUR boards and how all the boards are connected together.
        BN44-00617A
        Shopjimmy does not have the pictures for me to look at either.
        So far it look like it has two set of LED power supplies.
        Those two service manuals do not show anything much about the power supply/LED driver board.
        I need to see the chart of the power supply board connector pins.

                        Picture is to blur to be able to read any printing on the board especially the charts that show what the pins of each connectors are for.
                        Just remember this, we do not have the boards in front of us to look at, the only thing we can go by are the provided the pictures, if you cannot read any prints on your pictures then we cannot read them either.

                              Looks like the 13v is only about 8v, the other voltage appear ok. So do I assume if the Back-lights flash with the main board disconnected, that the Power board is faulty.

                                        Start a new thread with a description of you issue and if you did any tests what are your findings and pictures. Yes pictures so we can see what you have.

                                          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.

                                          Initial Issue


                                          The laptop initially presented graphic issues and driver failure (Code 43) for the GPU.

                                          After preventive maintenance (cleaning, thermal paste, etc.), it powered on normally. We disassembled it again to inspect the GPU, reassembled...

                                          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 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.

                                          Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock

                                          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

                                          After all of...
