    Nice Samsung UN50H6203AF Bad Tab Bond Board

    Got a nice Sammy UN50 SMART TV with the right Tab Bond board (at least, what I call "Tab Bond Boards".. Dunno the official name for them) bad...

    I can confirm that the TCON is good. In the pictured TCON, 3 blue LEDs come on when the right connector of the TCON is not hooked up.. The half that IS hooked up gives me a perfect display

    When the right connector IS hooked up, the marked Blue LED slightly flashes blue and then goes out and I get no display, just backlights.

    Normally, with a Tab Bond board problem I would just treat it as a broken panel and gut the TV for parts and LEDs.. But this one is really nice and the actual tabs don't seem to be messed up and there are no obvious burns or blows. So I am hoping that it's simply a bad component that can be run down and replaced...

    Any ideas???

          HOLY CRAP!!!!

          Read thru the link, part of which referred me to this youtube video

          https://www.youtube.com/watch?v=T8Vu...ature=youtu.be

          The suggestion was to cut the microtraces on the left most tab.. I thought that it was crazy but figured what the hell..

          My plan was to cut a single trace at a time.. Being ham-handed as I am I probably ended up cutting at least 2 at a time..

          But, after the third cut, holy crap it worked!!! The full display came on and there doesn't seem to be any obvious consequences. No lines in the screen or anything..

          Never would have thunked it..

          Thanx for the link Neil!! VERY much appreciated..

              My solution was to block the connections on the ribbon connector with scotch tape. Easier than cutting the flex.

                  LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
                  by Hakuu
                  Hi There,

                  This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

                  After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

                  More Details

                  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...

                  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...

                  by m1ch43lzm
                  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....
