    Samsung Smart TV - No HDMI working

    Hi guys, this is just a general question but if this TV has got 2 HDMI ports and both do not work what could be the problem.
    So If I feed a signal to the HDMI1 and put my TV to that source all I get is a blank screen. I do not get a "no signal" message. If I switch off my DVD player (The source) then I get a message saying no signal.
    Software is up to date (Tried updating it) - Don't know how to back roll the update.
    Also I don't know what to look for in service mode that might have a bearing on this issue.

    Regards

      Possibly not helpful but just because I had a dvd player fail today in a very similar way have you tried a different device on the HDMI inputs? Perhaps a computer or laptop that will detect a display.
      Also check the hdmi cable?

      With out having a look inside the TV I once had one where the tv would show everything on the onscreen display but no HDMI inputs.
      I heated the processor and the inputs came back.

          Bad hdmi chip. Lack of voltage to hdmi.
          I assume no responsibility for any stupid suggestions I might post.

              I have ordered new board already. Just very expensive.

                  I have tried different devices, no luck. But yes it would be the main board. So i will order a new one.

                          Samsung UN50MU6070FXZA - HDMI Ports Not Working
                          by grimacelord
                          Hello. Samsung UN50MU6070FXZA here with both HDMI ports non-working. I have already verified multiple sources and multiple cables to ensure it isn't something simple like that as well as resets and software updates.

                          I took the mainboard out and gave it a look. Nothing looks bad or burned. All of the HDMI pins are nice, none are broken at their pads either.

                          Following the traces, it looks like both HDMI ports trace back to the main CPU which does seem to get hotter than I think it should despite it's (rather poor) heatsink.

                          Since the HDMI controller appears...

                          ASUS ROG STRIX B550-I GAMING - M.2_2 port not working correctly with SAMSUNG SSD980 1TB NVME SSD
                          by DynaxSC
                          Hi,

                          I have an really very weired issue with ASUS ROG STRIX B550-I GAMING.

                          Some NVME (PCIe) SSD's are not working correctly in the second M.2 socket. An example of it is the SAMSUNG SSD980 1TB NVME SSD.
                          Some other NVME (I have only smaller ones) disk do work without any problem, also SAMSUNG disks, eg an MZVPV128HDGM-0000.

                          The behaviour is also really very strange, i.e.:
                          • The disk shows always up in BIOS - so it is recognized, so far so good
                          • POST-ing with this disk with fresh Windows 24H2 installation (done in the M.2_1 socket) in the M.2_2 socket
                          ...

                          GTX 750 HDMI output not working
                          by hinisa
                          Hi

                          I have an GTX750-FML-1GD5 with a non-working HDMI port and I'd like to figure out what's the cause and if it's easily repairable.

                          GPU is working fine. VGA and DVI-D ports are also working just fine. But whatever monitor or TV I plug into the HDMI port, it isn't even recognized, let alone giving a display.

                          I took a glance at the HDMI port and couldn't see any obviously broken parts.

                          I've also read on various forums that some firmware versions have non-working hdmi, so I flashed dozen or so different VBIOS ROMs that I acquired from techpowerup...

                          Samsung UA40J5200AK missing Smart features?
                          by x_orange90_x
                          I picked up this TV a couple days ago and it's SUPPOSED to be a smart tv, however it doesnt have any apps or wifi settings to change. I cannot find this EXACT model, it's actually a slight variant that is turning up this information. This is a UA40J5200AKXZN.

                          The interesting thing about this tv is where it was made. It was made in Egypt. The closest information that I can find that could apply to this model is the following website:
