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