    Re: UN55H6350AF cycling on for 12 seconds off for 2

    So if I get a programmed spi chip, you think that will solve this issue?

      This tv is such a pain in the ass, I'm thinking about converting it to crt.

          I saw one for a 50 inch while scouring the web, do you think that one would work? Thanks.

            There is the same mainboard, the goofy eeprom/spi is under the lower left tang of the bga heatsink, pita, would have to remove heatsink to replace it, never a break with this sumjunk: https://www.shopjimmy.com/samsung-bn...350afxza-th01/

              I think this datasheet matches my eeprom pinout, my eeprom is 25Q40CLSIP 1407, not sure but I shorted pin 5 and 8 to try to reset eeprom, no change: https://datasheet4u.com/datasheet-pa....php?id=951134

                It's not the eeprom that is faulty, the TV is turning on. The NAND isn't under the heatsink.

                  Not sure, my 8 pin 25Q40CLSIP is under my heatsink, it says spi right next to it, I thought that's what was the issue?? Photo in post #25.

                    Or are you getting my tv mixed up with SoftwareHack's tv?

                      It's tiny, and has the turn on instructions. It's very different to the large NAND that holds the software. It's to the left of the optical port in the photo.

                        Oh, shit, if it's tiny, I can't change it, hands are too damn shaky, gonna have to get a new board I guess.
