    digihome ptdr24hds3 backlight only no picture

    this one landed here . owner said he plugged in a lightening connector converter to hdmi then the picture and sound went off . i am wondering if its a firmware problem ?
    from what i can figure out the voltages seem to be ok . i can check any again if needed .
    what it does as soon as its plugged in is the standby light flashes then the backlights come on then it flashes some more and goes out . backlights stay on for a minute or so then go off .sometimes it goes through this 2 or 3 times on its own .all the while backlights are off there is a very quiet click sound from the speakers like its tripping . there is no response using the remote or pressing rear toggle switch/button
    here are some pics .

          i found this but cant figure out where to download the 2 files . https://translate.google.co.uk/trans...search&pto=aue
          17MB211 17MB211S Full Software Installation Method:
          the shredder_usb_update.b
          shredder_usb_update.sc is
          Copy the named files into the empty and formatted FAT32 USB stick.

          Plug the USB memory into the TV's USB-1 port and while holding down the “ OK ” button of the remote control, plug the ac cable into the wall socket and hold it until the standby led starts to flash quickly.

          Release the “ OK ” button when the standby led starts to flash quickly . When the standby led lights up, software installation process is completed.

          As a result of this process, do not install " FULL " software with different serial numbers on the TV since the panel information will change !

              Just above the comments there are 5 links, Vestel, Toshiba, Telefunken, Hitachi and JVC, they go to google drives, they won't work from the translate page, you have to go from the original.

                  well then ..just talked to the owner again and now he tells me the tv worked fine for 2 days after he had used the lightning/hdmi converter then one day wouldn't power on ..and he runs it off a modified sine wave power inverter . but had been fine for months .
                  he had it in his head it must be the hdmi converter that damaged it ..i dont think so myself .

                      Please can someone point me from where to download the full software installation as on the link above, even if original and no translated, I cannot find any link to download the full software.
                      Many thanks in advance.
