    LG55EC930V with faulty mainboard

    Hi mates, did'nt find any better topic. Here is an LG55EC930V with faulty mainboard. The MOBO rev number is EAX65612206(1.1). There is two type on ali, 65612206(1.1) and 65612205(1.0) both for the same TV model, but the last one is 50% cheaper.

    What is the difference on this two mainboard? Clould be only region or must be order the exactly same 1.1 version?

    2206(1.1)

    2205(1.0)

      Thx, The slot is not important, the lvds port i can change, pins the same. Do you think must work with the T-CON together?

        One has a CI+ module connector and the other does not, also the displays used in the tv's where they came from are different.( LC550LUD (LG)(P1) and LC550CUD ).

          I see this site is aliexpress, are these boards original?
          I noticed through this thread that the LVDS connection on my replacement mainboard is different than on my old mainboard.
          could that be a problem?
          The TV is currently in the basement because he still had problems after MB replacement, but wanted to get it up again soon.

              why will both not working? I ordered another mainboard for LG B6 OLED and worked perfectly. Aliexpress also has guarantee like ebay, have many times refunded by quality problems.

                here we are talking on same point. one time being lucky doesn't mean always.

                most main boards or Power Boards sold on this platform are articles which failed with QC at Manufacturing.

                    ths issue are knowing to any whom lived and worked in china long time, and i am one of them.
                    OP show here 2 sources of the MB. Lotas explain with photo but with out the point i pointed.
                    one failed C+ socket. other installed wrong LVDS socket. this is wrong manufacturing mounting which failed within QC. there are other issue could failed with QC like dropping down current... leak... damaged one DDR... etc.

                      Yes, true story, buy mainboards from ebay.
                      And another thing, OLED EC series mainboards are very reliable, what problem has the TV?

                        Samsung UE50AU8072 all time rebooting, backlight ok. Maybe mainboard faulty?
                        by badboyzzz
                        The motherboard initially receives voltage for VGH, but it constantly reboots. When I remove the flex cable at the bottom, I hear normal sound, but there is no image on the screen and it is black on both sides. This time there is no voltage on VGH.

                        MASTER TL240 and new mainboard LW36BKC01
                        by orcic
                        Hello,
                        I have an old MASTER TL-240 LED TV. Since it stopped working and it had a DVB-T receiver that is being dismissed in Italy, I've decided to replace the mainboard with a DVB-T2 one.
                        The original problem was that when switching on the TV, the power LED was transitioning from red to steady blue, without showing video or audio.
                        After checking some voltages on the power supply board (HKL-240101-B Rev. 1.4, HKL from now on) someone suggested me to replace the mainboard.
                        Now I have some doubts about how to connect the new mainboard to the old power supply.
                        First of...

                        Vizio M43-C1 - How closely do I need to match the mainboard number?
                        by Devonavar
                        I have a Vizio M43-C1 stuck in a reboot loop with no backlight.

                        I've tested all the voltage rails coming out of the power supply and they are "normal" for this model (PS_ON & DIM go high when turned on, BL_ON & 3D_ON are close to zero due to backlight power flowing through the mainboard, 5VSB is 5V, and 12V is 19V, which is apparently normal for this board).

                        Basically, I get similar results to Garry in this post: https://www.badcaps.net/forum/showthread.php?t=80346

                        So, I've ruled out the PSU for now.

                        The reboot loop...

                        QN65QN90A - Mainboard MLCC failed - now bootloop
                        by l0lhaxz1
                        Hi

                        I have a QN65QN90A which was purchased around launch I guess making it about 1.5-2 years old... had been working fine until a few days ago, simply went black and would no longer turn on (at all). No standby light and no typical PSU relay click etc. Absolutely dead.

                        Pulled it apart without doing much research first, suspecting the power supply as it had a faint buzz (I guess due to the forthcoming found short), investigated PSU for some time and concluded there was no fault that I could spot with the board removed.

                        Came to learn after a bit more research...
