    Samsung UN50EH500FXC

    Hello
    I am at a loss. I bought the TV knowing the following:
    There is sound but no picture but I have back lights
    The previous owner has changed the T Con board however didn't keep the old board.
    I have changed the main board with no change.
    I have changed the power supply board with no change.
    I am sure that the key to this problem is that there is no video and that is why I changed the main board.
    Would anyone suspect the T Con board or possibly one of the cables.

    Your input and thought would be greatly appreciated.

    Bruce

    Did you inspect the ribbon cables on the tcon to make sure that they are seated properly?
    Do you also get 12vdc at both ends of the fuse of the tcon board with ref. gnd.?
    What do you get on the screen if you have one cable between the panel and the TCON connected one at a time?

      Please also remember your replacement boards can be faulty in the same was as your originals are not all sellers test them, also did the seller replace the tcon with a exact match?

        Well here is an update.
        After some additional research and some help from some people much smarter than myself I think I might have solved the problem. As I had mentioned the T Conn board was replaced by the previous owner. When you do a search for P/N BN96-28859A you get a T-Conn board that this P/N is nowhere to be found. After some emails I was directed to closely look at the #'s on the sticker on the back of the board and there you will find 28859A in the start of the string of#'s. My question would be "are these boards compatable being as they have the same #'s on the front of the board or is there perhaps programing differences on the chip. Your thoughts would be appreciated.

          Hello Bruce,
          Can you confirm the model number because nothing comes up on google.

            The important numbers are the numbers printed on the barcode sticker.
            This TV model uses more than one LCD supplier, and even with the same LCD maker they will use different model LCD panel.
            http://www.shopjimmy.com/catalogsear...sung+UN50EH500
            So you need to look at the LCD panel model number and look at shopjimmy site.

              Re: Samsung UN50EH500FXC

              My thoughts are that if the previous owner changed the Tcon board, is the replacement the correct one for that set?

                Re: Samsung UN50EH500FXC

                Thank you everyone for your help. I have been able to find out that there are two T-Conn boards that are recommended for this panel. M$35-D094303-L$VR333507XP02 this the one that I have and the other starts with 28859A so I am going to take a chance and order it. If nothing else I will have a lot of spare parts for sale.

                    Update I ordered the T-Conn board with 28859A at the start of the # on the sticker from SJ and they sent me a different board which didn't work as well. I need to have confirmation from someone as to the correct T-Conn board for this TV since I don't have the original failed board to compare to. Any help would be appreciated.

                      Look at the Panel No. and search for a T-CON suitable for that Panel.
                      As budm pointed they have same Model Nos. but different Panels therefore different T-CONs.

                        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.

                        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.

                        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...

                        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....
