    HiSense 50K360G Button Lock

    Had a HiSense come in.. Powers up great, goes to screen. Everything is displayed OK..

    But the buttons don't work on the button board.. Only the ON/OFF works...

    Same with a remote.. Only the ON/OFF works, nothing else..

    The display says NO DEVICE ATTACHED and stays on, even when I hook up a DVD player or something..

    Everything looks good, it's just "locked"...

    Any idea???

    I am thinking a firmware update if possible...

    Have you tried holding the MENU button while turning on the tv? This is suposed to fix it if it is stuck in USB mode

      Yea, no luck..

      And there doesn't seem to be any firmware available...

        Just for sheets and greens, I booted it up with a thumb drive in the USB Port.. It booted up and showed the contents of the thumb drive, but still none of the buttons worked...

          After an hour long chat with HiSense I learn that no firmware is available..

          Seems if I want this one fixed, I am gonna have to replace the board.

                    Possibly... I researched it and it seems that it's "bricked".. Likely TV lost power during a firmware update... Which doesn't make much sense since HiSense.. (sense?? since?? HiSense?? I crack myself up.. ) says that there never was a firmware released for it..

                    Since the TV does read a USB at bootup, I am hoping redoing the firmware will help..

                          Didn't seem to address my issue..

                          But I did get a new BIOS chip from EBAY...

                          But I am not sure where the BIOS chip is...

                          Attached is a pic and the chip I think it is, says EM24C32F, is marked in red..

                                Just an update.. A new firmware chip did NOT fix the problem

                                  OK Update on the update...

                                  Just for sheets and greens, I grabbed a HiSense remote that I had flying around...

                                  Had the TV on and pushed INPUT on the remote.. SOME BEACH!!! It went to input!!! Used volume and stuff and it all worked!!!

                                  Then I shut it off and turned it back on and ALL the buttons on the button board worked!!!

                                  When I tried a "remote" before I just used a UNIVERSAL programmed for HiSense...

                                  Maybe I needed an actual HiSense remote to kick it in gear..

                                  Go figger....
