    Thanks Tom. We tried contacting Sharp, and they said they didn't have any of those files, or are unwilling to give it to us. It does no have a usb port, but does have SD card slot.

        The firmware may be out there somewhere. You might have to get creative with search terms to hunt it down, though. I had a hard time finding firmware for a Sony TV, and I stumbled across it after a couple days of searching.

          My tv is doing this exact thing with the no picture, but sound. If we wait and turn it on it'll eventually work, and doesn't do it every time, but it's becoming more often. It's not a totally black screen, but more like a dark blue. What can I do?

            It sounds like the backlights are still on but no image on the screen.
            Look at the TV in the dark room to see if the backlights are on or not first.

              Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
              by TR103
              Hi, I have a Samsung UE50TU with:
              - sound and backlight, but no picture
              - when it arrived, it had a picture for a few seconds
              - it keeps rebooting
              - without ribbon cable between the two panel boards, it does not reboot but I have no picture
              - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
              - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

              - without cable between mainboard and lcd panel and with a jumpered...

              Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
              by Mgiffune
              I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started β€˜fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

              I ordered a supposedly β€˜new' Tcon board this time, and

              Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
              by Ierwin
              Hello everyone,
              Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
              The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
              He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
              I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
              Anyway I still fully expect that there has been something seriously damaged...

              Samsung UN70NU6900F no picture and no sound
              by jchang
              Hi all

              I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



              Symptom:
              No picture no sound.
              When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
              No sound at all.



              What I tried:
              1. I tried unplugging the left or right ribbon...

              what i went through dealing with my mobo with dead onboard sound!
              by ChaosLegionnaire
              so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

              i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
