    I will sell a motherboard for Sony 2015 GN1-T XF segment, matching the models
    KD-55X850xC
    KD-65X850xC
    KD-75X850xC
    x-> 5, 6, 7, 8, 9, e.g. KD-55X8505C

    The module has been regenerated, a new eMMC memory has been installed, which is most often damaged in these models. All functions work on the board, CI +, HDCP, Netflix .... just like the original.
    The error counters, working time counters and the serial number have been reset (you can program the serial number of your TV). I will help you get started. 550 PLN.

    Hello Sir,
    Do you still repair those Sony motherboards?
    I have a KD-65X8505C that is in a boot loop after a software update. It goes to the Android logo, then freezes and restarts continuously.
    Please message me for details.

Topic summary

✨ A motherboard for Sony 2015 GN1-T XF segment TVs, specifically models KD-55X850xC, KD-65X850xC, and KD-75X850xC (where x represents digits 5-9), is offered for sale with a newly installed eMMC memory module, which is a common failure point in these models. The board is fully functional, supporting CI+, HDCP, and Netflix, with error counters, working time counters, and serial number reset, allowing reprogramming of the TV's serial number. Several users reported issues such as boot loops, freezing after the Sony logo, and backlight shutdown, often linked to eMMC faults. Repair services and replacement boards are available, with the seller providing private support and guidance for setup. Requests for eMMC dumps and repair procedures were made, but detailed technical instructions were withheld. Some users experienced Netflix malfunction after eMMC replacement, likely due to serial number resets. The discussion includes troubleshooting of boot issues, eMMC reprogramming, and offers of repair or replacement motherboards for affected Sony TV models.

FAQ

TL;DR: 550 PLN "new eMMC installed" boards fix Sony KD‑55/65/75X850xC boot loops, with counters reset and full functions. Seller also offers repair and help getting started. [Elektroda, Adam4321, post #19329100]

Why it matters: This gives owners and repair techs a fast path to resolve 2015 Sony X85C eMMC faults and software boot loops.

Quick Facts

Which Sony TV models does this board fit?

It targets 2015 GN1‑T XF sets: KD‑55X850xC, KD‑65X850xC, KD‑75X850xC. The suffix x covers digits 5–9. That spans three panel sizes: 55, 65, and 75 inches. Example: KD‑55X8505C. [Elektroda, Adam4321, post #19329100]

What are the symptoms of an eMMC failure on these TVs?

Typical signs: the TV hangs after the Sony logo, the backlight then switches off, and it ignores all buttons. No LED blinks appear. These behaviors strongly suggest a failing eMMC on the mainboard. [Elektroda, rtammes, post #19578692]

Do you offer repair service or only a replacement board?

Both options exist. As the seller noted, “MB repair is possible,” and at times a repaired board is available. Message to arrange service or availability. [Elektroda, Adam4321, post #19634990]

How much is the regenerated board and what’s included?

Price is 550 PLN. The board has a new eMMC and, in the seller’s words, “All functions work on the board, CI+, HDCP, Netflix.” Error and working‑time counters are reset, and the serial can be programmed. He helps you get started. [Elektroda, Adam4321, post #19329100]

Will Netflix, CI+, and HDCP still work after the swap?

Yes. The seller explicitly states the regenerated module preserves CI+, HDCP, and Netflix functionality, matching the original board’s features. [Elektroda, Adam4321, post #19329100]

Netflix stopped working after my own eMMC replacement—what now?

This edge case does occur: users report Netflix not working after an eMMC change. Engage a qualified service to properly provision the board and verify device parameters. That restores app functionality on these Android TVs. [Elektroda, aakashhukpachongbang, post #19939780]

Can I program my TV’s serial number on the new board?

Yes. The seller resets counters and allows serial number programming for your specific TV. He also offers help getting the board started in your set. [Elektroda, Adam4321, post #19329100]

How do I contact the seller or arrange a repair?

Use the forum’s PW (private message) button under the user’s post to initiate contact. That’s the recommended method for arranging service. [Elektroda, DiZMar, post #19645525]

Is the KDL‑55W809C covered by this specific board?

No. The listing is for 2015 GN1‑T XF KD‑55/65/75X850xC models (suffix 5–9). KDL‑55W809C isn’t in that set. Contact a technician for that model. [Elektroda, Adam4321, post #19329100]

Can I get an eMMC dump or a public step‑by‑step "how to"?

No. The seller stated he will not answer public “how to” requests. Contact privately if you need service or assistance. [Elektroda, Adam4321, post #20141784]

My KD‑65X8505C is in a boot loop after an update. Can it be repaired?

Yes. The seller offers mainboard repair for these models, which addresses common eMMC‑related boot issues. Message to arrange the service. [Elektroda, Adam4321, post #19634990]

What happens to error and working‑time counters after replacement?

They are reset on the regenerated module. You can also program your TV’s serial number during setup for proper identification. [Elektroda, Adam4321, post #19329100]

How do I proceed to get this fixed quickly?

  1. Confirm your model is KD‑55/65/75X850xC (suffix 5–9).
  2. Note your TV’s serial if you plan to program it.
  3. Message the seller to arrange purchase or repair; he will help you get started. [Elektroda, Adam4321, post #19329100]
