    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:...

                      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                      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

                      Sony XR-65A95L no power due to logic board issue
                      by joliver82
                      Hi guys!

                      I'm trying to repair a TV that a friend gave me recently. Lightning struck next to his house and broke the TV apart from more electronic devices.

                      First of all I've checked the power supply and it works as expected. I removed the logic board and shorted the 3.3v standby output to TCON_ON and POWER_ON and every voltage was generated as expected (12v and 25v for logic board and 32v for TCON).

                      When trying to boot the TV normally (having the board connected), the TCON_ON signal is not generated from it which made me think there's some issue in the logic...

                      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....
