    Re: Eeprom dump thread!

    it seems that if the chip is blank it shows
    recognition error
    i am now able to write to chip
    but it only took a few seconds to write is that normal?
    i expected it to take more time?

      Eeproms are written quickly, but there should not be a recognition error, most likely you have not recorded anything.

                        What's the problem with the TV?
                        What is your motherboard number and what is the panel (matrix) number?
                        You can read the data (dump) from your eeprom and post it here.

                                Thank you so much! You are a genius.
                                I wonder if you can change the panel in this firmware, Mainboard CV3393BL-C original panel is HV236WHB-M00 but I need the V236BJ1 panel,
                                the reason is that I need to flip the image, or how can I flip image? Service mode don´t work

                                        there must be function to save changes. try with ok or (>) arrow button or vol/channel + button.

                                            by (0)_(0)
                                            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...

                                            Does anybody have an eeprom dump file? I really appreciate any help.
                                            Thanks in advance.

                                            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...
