    Aliens.....

    Looks like the start of a failed AS-15 gamme chip on the T-con, time to take some t-con voltages!

        Panel is fucked trash it, take the frame off and check the tab bond drivers I bet that the one located about the grey bars is burning hot due to being shorted and causing that glitch with the screen, seen it lots on samsungs.

            Why the bottom part still works well, all across the screen. That is weird, no?
            If that part of the screen would be bad, then it would be bad all the way to the bottom, no?
            The icons, shouldn't have color in them?
            How about a picture from the front?
            Which model is it? It would be nice, if everybody would include that in the title.

                If the menus appear perfectly over the green part then it's not the panel...

                    Try going in to the service menu(plenty here on how to do that) and cycle through the screen types and sizes, might help.

                      you sure the tcon you fitted was ok, does look like voltage buffer (as15 or eqiv) failing. did you check fuse on orig tcon ?

                              Press in the following order on the remote 'info' 'menu' 'mute' 'power' the tv will turn on and the service menu will be displayed. Use 'up' and 'down' on the remote to go through the options and 'right' and 'left' to select the options.

                                  Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
                                  by Asraf Atb
                                  Hi everyone,

                                  Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

                                  Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

                                  I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

                                  I came across a 50inch TU8000 that wouldnt start up properly (blinking stand-by light, backlights would cycle on and off).





                                  When i opened it up and removed the power to the mainboard the backlights powered up and everything looked uniform.
                                  When reconnected the mainboard but disconnected the flex cable to the panel i heard the TV startup with the intro sound.






                                  Later I checked for shorts on the panel PCB boards but could not find anything.
                                  When I took a look with the FLIR i noticed the 2 resistors...

                                  Hoping someone here could possibly help. I have a few questions in regards to compatibility with main boards. But I'll give a quick short run down on what's going on first;

                                  I have Samsung Smart TV UA65MU6100WXXY version DA01

                                  Now years ago it started intermittently playing up after a lighting strike. Lighting hit the block of units i was living in at the time. Ever since that night the TV started having a mind of its own, It would randomly turn itself off or on, and all inputs stopped responding like HDMI, aerial, but USB still worked. Anyway, over the next few months...

                                  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...
