    Hello, the TV keeps rebooting after turning on, turning on the colorful circles start spinning and after about 3 seconds it turns off and on again and so over and over again I suspect that it may be software on emmc on the motherboard. The backlight works properly when the hob is disconnected.
    The voltage on the board is correct.
    I called the store to buy a new board and was told that the board fits different sony TV models and should be properly programmed.
    Is it about programming with a batch of emmc memory, or are such new discs programmed in a different way? Where can I find the batch for this TV?
    I heated the hot-air processor it did not help.

    I forgot to write about it, the diode is not blinking red. Lights up white all the time goes off when restarting and lights up white again.

    So self-test doesn't work, it should throw out the blinking code

    It didn't blink red and that's why I heated the processor up, but no changes were made after warming it up.

    Can I replace this emmc SK Hynix H26M52103FMR memory with e.g. Toshiba's THGBMBG7D2KBAIL memory. Both have 16 GB of capacity. It would be programmed with an original batch from a good album. The manufacturer doesn't really matter here, unless it's about some other parameters?

    It's the same for me. TV less than 3 years. Anyone found a solution or knows where the motherboard is available?

    THGBMBG7d2kbail to Extended CSD rev 1.7 (MMC rev. 5.0 ) housing (Toshiba BGA153)
    The other one H26M52103FMR is (Hynix BGA153)
    HAG2e ---------- H26M52103FMR is in Lenovo TAB 2 A7-30DC plank

    Do you think rewriting the feed from TV1 to TV2 will heal him?

    There is a guy in Poznań who (supposedly) repairs these CDs, but you have to deliver all the tv to him. It also repairs discs marked 1-894-596-22 from TV sets such as KD-55X8507C.

    In some Sony, the processor and memory are allegedly matched by software, so that replacing the memory itself (programmed at home) is out of the question. In a word, a very complex topic.

    If you do not have certain information, do not clutter the forum with such nonsensical entries, if you do not have enough points, it is enough to ask, I will gladly kick a few so as not to see such embarrassment.

    Yes, it would be best to give only 100% verified information. However, I think that such a general exchange of thoughts also has its value. If you think that we are writing embarrassment, give you 100% advice. As you can see, these C series boards are in short supply, they are in demand (why read embarrassment, announce yourself and make them).

    On Ali .. this and that, both the H26M52103FMR memories and the MT5830BPHJ procki are sold in buckets, but not included. If it were like you write:

    Then what would be the point of buying and replacing the proc or memory alone? Let's exchange these thoughts ;-)

    I only made a general point, which does not necessarily apply to this case. Regarding Ali, the sites authorized use these procks and memories for sure. Unauthorized repair points may be using it, I don't know. After all, I did not rule out replacing the processor or memory individually (the manufacturer uses them separately on the line as well). I just expressed the thought that there is a tendency among manufacturers of equipment (especially the new one) to protect their products against further repairs, this is all and that is all. If someone has the time, is willing, it is even advisable and laudable to be determined to pave the way (perhaps one of the first).

    I did not know that authorized services replace procks on plates, but well, I am sitting in dry plaster :-) ignorant ...
    Everything can be fixed if not buried, returning to the topic, how do you think, will the input from another TV raise Tv in the subject? As in this question:

Users suspect the problem may be related to the eMMC memory or motherboard. Various troubleshooting steps have been suggested, including checking for self-diagnostic codes, attempting software updates from the manufacturer's website, and heating the processor. Some users have reported similar issues with other models like the KDL-55W809C. The conversation highlights the difficulty in obtaining the correct programming batch for the eMMC memory and the high costs associated with repairs through Sony service.
