    Sony XBR-75X850C Mainboard EMMC memory chip

    Need a little help here. Story is the tv was dead. No power, No led, no backlight, nothing.

    Replaced EMMC from an eBay seller. Tv powered on and flashed amber/ green led. Updated firmware via usb. After 20min or so white light flashing and update appears to be done.

    However tv keeps rebooting (boot loop) as soon as the Android startup screen comes up. Tried hard reset holding down power and volume - button. Tv restarts and screen freezes on this circle image.

    Boot loop on these models is usually a sign the EMMC memory chip is bad or going bad.
    Did I miss something or this is a used chip maybe? Reprogrammed and reballed?

    Any help or suggestions would be appreciated.

    Thanks

      Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
      by acedogblast
      This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

      There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

      BGA153 eMMC Chip Writer Needed
      by GMAN-2022
      Hello,

      I have a home automation controller (Control4) where the eMMC chip where some sectors on the chip is corrupted. The controller runs a linux based system. I believe the bootloader/kernel is bzImage.

      The model of the eMMC is SanDisk SDIN8DE2-8G.

      My objective is to purchase a new SanDisk eMMC chip and flash a working image on the eMMC chip before I take the circuit board to the local electronic shop to remove the old chip and install the new chip. I have confirmed with the local electronic shop that they are able to remove and install the new eMMC...

      by Morosan Dimitrie
      Hello guys, can someone help me with an eMMC dump for a Sony KDL55W-955B TV, I tried to read the original memory with the RT809H but it shows me that it only has 1888MB even though it should have around 3.8GB. On a new memory it shows me 3776MB. From what I found on the Sony page, the following models could also be compatible:

      KDL-65W955B, KDL-55W955B, KDL-60W855B, KDL-50W805B, KDL-42W705B, KDL-32W705B, KDL-48W605B, KDL-40W605B, KDL-60W605B, KDL-55W805B, KDL-42W805B, KDL-48W585B, KDL-32W706B, KDL-42W706B, KDL-42W815B, KDL-42W817B, KDL-50W815B, KDL-55W815B, KDL-42W828B, KDL-42W829B,...

      Asus Chromebox CN62 - wrong chip put on BIOS reader
      by BMCappelletti
      Long story short:
      - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
      - gave the computer to his son a couple years later
      - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
      - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
      (seems like the story was not that short)

      He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...
