      Re: Un50mu6070 Mainboard issue

      Hi lotas,
      I have a motherboard from Samsung UE49MU6202, code BN94-12424C and don't have stand-by led active, attached 25Q40 that probably need to be fixed.
      Can you help me?

          Ok, I'll try, you are familiar with the status of the register, what needs to be set, without it the firmware will fly off again when you turn it on for the first time.

            I see that you write in the post:
            In the program:
            1. Click "Detect Chip" and select W25Q40CL and "Select IC".
            2. Click "Unprotect".
            3. Click "Erase IC" and "Yes".
            4. Click "Open File" and select your corrected Dump.
            5. Press "Program IC" and "Yes".
            6. Click "Verify IC".
            7. Press the down arrow to the right of "Unprotect" and select "Edition SREG", put a check mark on S7, S3, S14, S9 and press "Write" and "Yes"
            7. Close the program. Ready.

              On RT809H interface must be set anything in tab Protect when you read W25Q40 ?
              Because i see your info when you have to click to programming IC's...

                  Hi Lotas,
                  I deactivate protection and erase two ic's, tested as blank.
                  Write each of versions that you fixed for me and protect both ic's...no one was working...
                  Any ideea?

                    Re: Un50mu6070 Mainboard issue

                    Write down any dump (you need to look with which one it will start, it can start with any) after recording, set S.R. 0x88, 0x42 and hit "write".

                    And it is not clear why you are erasing two microcircuits, what else have you erased? There is one chip 25Q40.

                      I erase two ic's and write each of them with those two versions received, set SR as you recommend you, tested one by one but no stand-by led active...

                          Now you can read the Dump after installing it on the board, and post it here again, I'll take a look at the contents.

                            Do you have two new 25Q40 chips or one native second from a donor?

                                            Hi everyone,

                                            I am trying to fix a samsung washinmachine power supply main board.
                                            I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
                                            Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
                                            The power supply board reference is the following: DC41-00189a
                                            I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel...

                                            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...

                                            Sony Bravia KDL-70W850B T-CON board / software update issue
                                            by eclectric
                                            Hi, I'm hoping someone can help me with this issue before I give up on this TV.

                                            In short, I replaced the T-CON board due to an error code indicating that was the problem, after which it flashed a green and orange LED meaning software update required. I cannot get the tv to do the required update via USB, so I am stuck.

                                            Here is a rundown of the symptoms and the steps I have taken to troubleshoot:

                                            I inherited the TV with the symptom that it would turn on, then turn off after 5-10 seconds and a red LED flashed 4 or 5 times. Sometimes it would be 4, sometimes...

                                            Nikon D5 – dead, power board issue ?
                                            by corrize
                                            Hello, the DSLR has heavyly fallen. It is dead : no sign of life and display nothing.

                                            When it worked, it always displayed a card present state on LCD display, even when the battery is empty it display a empty battery symbol.
                                            I found a dead fuse, I replaced it and a mosfet burnt, I changed it and another fuse burned. Nothing burned after. And I can't find any short circuit anywhere, it's weird.

                                            Now, I try to understand how it works.

                                            There is two boards (the little one on pictures has no component) : the first is a « power board » : managing...

                                            ASUS VG32UQA1A t-con board issue
                                            by damndenis
                                            Hello everybody,

                                            This is my first post here, I've always loved to tinker with electronics, but never got in-depth with it. Hope I can learn a thing or two from this forum.

                                            I've got a 31.5" Asus monitor which distorts/flickers at equal intervals of a couple of seconds. From what I've gathered, it's an issue with the T-CON board, but feel free to correct me. Shipping from the manufacturer would cost 3x as much as the part itself. I was wondering, if there is a way to diagnose the board itself and replace the faulty components? I'm good with soldering, but not at all...
