              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....

              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...

              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...

              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...
