    Compatibility issue?

    Hi there

    I have a LG 55LB5820 - TB and need to replace the power supply.

    The power supply I have is EAX65423801 rev 2.0

    I have found a EAX65423801 (2.1) from an LG 50LB5610 and the markings on it are:

    PCB: EAX65423801 (2.1)
    REV2.0
    2013. 12.10

    Would this be compatible? Not sure as it is a different size tv

    It is the same part number but different revision?

    Is that just a software difference or can it be a part difference?

      That is the blank PCB part number and it could be populated differently for different models. The connectors may be different. Different size tvs will have different configuration and voltages for the LED strips so likely it will power the main board but not the LED backlight.

          Those two boards look pretty identical, I would be surprised if it DIDN'T work.

                  There's 10 LEDs different between those two models, they will be putting out different voltages.

                      They both look identical except one transformer is white and the other is blue. However there is a difference in voltage. Stay with the one you have

                          MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
                          by rounin
                          Hi everyone,

                          I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

                          🛠 Original Issue
                          The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
                          Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

                          I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

                          ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

                          Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
                          by ugamazing
                          I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

                          We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

                          Weired MSI B560M PRO (MS-7D20) - not starting with 11-th gen. CPU, 10-th gen. OK
                          by DynaxSC
                          Hi,

                          I have a very weired problem with MSI B560M PRO (MS-7D20), board is upgraded to the latest BIOS version v1.9.

                          The board is normally starting with 10-th gen. CPU, ie. Intel Comet Lake i5-10600K and Celeron G5905.

                          However if I install a 11-th gen. Rocket Lake i5-11600K the board powers up, but is immediately stuck on CPU LED, not progressing further. Debug card shows FF, and after restart with long short of Power Button: FE, which is as usually of no help (Reserved for future AMI error codes).

                          According to MSI compatibility site the board supports...

                          Alienware 15 R2 Service Tag: DL7NN32 ISSUE (Battery is not charging)
                          by Simone Vergani
                          Hello everyone,

                          I'm experiencing an issue with my Alienware 15 R2 (Service Tag: DL7NN32). The laptop works perfectly when connected to the AC adapter — it powers on and functions normally. However, the battery does not charge. If I disconnect the DC adapter, the laptop shuts down immediately, as the battery is at 0%. I have replaced the battery with a new compatible one, but the issue persists. I also replaced the AC adapter with a compatible one, but the battery still doesn't charge.

                          To assist with troubleshooting, I'm attaching two power circuit schematics:

                          Dynabook Satellite Pro C50D-B-100 - BIOS Issue, Black Screen
                          by wizard13
                          Hello everyone,

                          I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

                          I have checked the forum and the available documentation but could not find a solution specific to my issue.
