    Lg 50pa4500

    Hello, trying to do a test pattern on my LG Plasma TV, since I am getting a rainbow color screen on my TV. VA/VS tested good when power on. I have this logic control board, can't find my Auto GEN to jump it. Anyone know? This is the logic board I have.

          At the risk of answering incorrectly I think it's the pad in the small square just between/above the two connectors along the bottom of the board. I think you have to ground it.

              Jumper these two pads next to R452 and R451 and remove Lvds to run the PDP test patterns.

                  Got it, ran the test and test pattern came out like it should, looks like I have a bad main board, will order one and let you guys know if that fixes the problem. Thank you for the assistance.

                          It's not label, but the pins below R451 and above R452.

                                          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:...

                                          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...

                                          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

                                          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 (?)...
