        it can work even with no side working but sometimes it won't.

            I've seen it explained many times but still not sure exactly how it works, I just consider it magic when it does work. some explanation there by a very wise man: https://www.youtube.com/watch?v=pfrRhw7-ZII

                I took the ribbon cables out from T-Con to Panel Boards to inspect them, I'm assuming the issue is related to the highlighted box in the attached image. I wonder how this could have happened as this TV has never been taken apart before.

                    Eureka that's it, shit we should have checked that first, that's why I always try to do the basic simple inspections first, can save a shit-ton of chasing the wrong thing.

                        you might be able to trim it off evenly and make it work or just get another cable.

                            Tried trimming, with no luck. Going to order some new ones and come back with an update! Thanks for all your help.

                                No problem, I'm glad it was something easy to fix and not a shorted panel.

                                    inspect the connector it came out of, make sure there's nothing wrong that will mess up the new one.

                                        Driving a Sharp TCON/panel with a universal main board
                                        by advant
                                        This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

                                        I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

                                        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
                                        Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                                        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....

                                        Samsung UN65KU6290F PS board blows fuses
                                        by valvashon
                                        Samsung UN65KU6290F (May 2017); received from local Buy Nothing group. Was listed as "just went dead" and they wanted it gone. I brought it home, didn't notice anything visually wrong with the power supply board, looked up the cost of a new one and that's about as far as it went. Family was tired of tripping on the foot of the set so I decided to dig in and repair or toss.

                                        Can't believe that I didn't check it earlier but I found the main 8 amp fuse blown. Jumped across it with a 10 amp blade style fuse and you can see that it literally exploded inside the second I plugged...
