    Re: flatron L1915s

    Just pulled C203 and gave it a test:

    ESR = 22
    Cap = 3uF

    I'd say that's bad enough. I'll try to find a suitable unit to swap and test.

      I swapped in a 470u 63V and Bingo! we have lights. I'll see about ordering a set of good caps for it to do a proper job. Didn't think it would be that straight-forward.

          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....

          Will I have a bricked logic board after reflow of the GPU v-core U8900 chip on my Mid-2012 15" Retina Macbook pro?
          by korben_dallas
          Hi everyone! I'm trying to fix my black screen / failed U8900 GPU v-core on my Mid-2012 Macbook Pro 15" Retinaby doing a rework/reflow of the chip (once I determine that's the real issue; but it likely is).

          I've been disabling the GPU in NVRAM for a few years... but it's just time for a better solution.

          I'm new to soldering but the only feasible way to fix this issue is to do something myself.

          MY QUESTION:
          I've been seeing some people (on this forum mostly) run into issues with the logic board needing a serial number or it being deactivated (?)...

          LG 60PK550 Logic Control Board EBR63450301
          by Yanleb
          Hi all, I just want to share the repair of my 60PK550-UA TV set.

          The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.

          But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.

          All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
          C57: 3.30V
          C61:...

          Logic Board 820-00840-A Missing EDP_BKLT_EN
          by mferna14
          Hi dear friends., I am working on a Apple MacBook Pro A1708 , Logic Board 820-00840-A that has no backlight. The logic board powers on fine, but no display. After Checking on the backlight driver chip, I found that the EDP_BKL_EN is missing. And this Power Enable comes from the PCH. So does this means this Logic board cannot be repaired & brought back to life again? The resistance from GRD to the test point of EDP_BKL_EN is around is 0.66M ohms. R8442 (0ohms) is ok. Any suggestion/Tip if any would really appreciate. ​
