        This was the original dump, the one I corrected. After recording, did you set status register (0x88, 0x42)? Why are you recording someone else's dump 25Q80, does it belong to T-CON (for each panel model, it will be different)?

            I don’t understand why you are flashing 25Q80, it doesn’t matter whether it’s turned on, it’s intended for setting the panel itself, install the native, original one.

              Because in the package of files hosted online are present 25q80 and 25q40. Now i have restored original 25q80 and fixed 25q40 but nothing, dead.

                You correctly wrote down dump 25Q40, wrote down the status register (0x88, 0x42), I already asked you, but I didn’t get an answer, without setting SR, the firmware will spoil again the first time you turn it on.

                    For 25Q80 (0x98.0x2) there is nothing to install, it didn’t need to be touched at all, it is for T-con, status registers are installed after recording dump...

                        I don't know how you write everything down and why nothing works for you, if it was a native dump, then I fixed it and it should work...
                        Procedure for recording:
                        1. First you need to delete all status registers (uncheck all the boxes and click "Write")
                        2. Erase the chip.
                        3. Write down the corrected dump and check what was written down.
                        4. Set the status register (0x88, 0x42), check the boxes and click "Write"
                        5. Everything is ready, solder the chip in place....​

                          I think native original dump of 25q80 or 25q40 or all are incorrect because I re-write 25q80 and 25q40 following procedure of recording but nothing tv is dead. Only solution I think is a original dump with same panel.

                                I used sop8 adapter, but i think my original dump of 25q80 is demaged because;

                                After dump of 25q40 and 25q80 i flashed a files finded on line with this referece

                                samsung UE40MU6450U
                                Øàññè: kant_m_built_in
                                BN41-02568b
                                BN94-11958k
                                panel cy-kk040hgnv3v

                                and after flashed on 25q40 and 25q80 tv is turn on but screen is blu..the problems is my panel is cy-kk040hgnv3h not cy-kk040hgnv3v such as the firmware finded on line.

                                when i reflashed 25q80 and 25q40 tv wont turn on..is dead and after flashed 25q40 fixed from lotas..tv already wont turn on..a this point i think my original dump is not very well or correct.

                                i haven't solution.

                                    I don’t know what you messed up there, you posted a faulty dump, I corrected it for you, if you wrote it down correctly, then everything should turn on, try this one for your panel...

                                      please take your time and do things well, in pack3 there is no 8mbit dump, only the 4mbit one, post only the 8mbit from original dump.. lets see if it is drammatically empty, no correct connection (!!)... one lesson: on original dump reading EVER check the content with hex editor..

                                            Hello, This might be a long shot, but I'm looking for an EEPROM dump for a HP Photosmart C4280 All-in-one printer.

                                            The printer seems to be in cartridge alignment mode. Sometimes it print the alignment page and then hangs during the scanning step, sometimes it hangs during the printing process and sometimes it hangs during the boot process. If I let it idle for a while then it flashes the back-light of the top screen and there's a letter E. Bottom screen is asking me to restart it to no avail. I have to remove the power cable from the printer for a couple of minutes to make it work...

                                            Hi

                                            I was working all day on a 42" with no backlight = Driver is bad . LED Tester. Image exists

                                            As I was reassembling, I discovered faults on the screen ( used the LED Tester to power the strips).

                                            Right distribution board, 2 Flexs, near them:
                                            The one near the center has 1" line on screen. Pressing on the board-side or Panel side of the Flex bonding place results in some change, I sensed heating one time, but main fault line remains
                                            The other, pressing on the Panel to the Chassey and the lines disappears 99.99%

                                            I...
