🛠 Sony TV eMMC Recovery & Repair Guide

---

1️⃣ Understanding Sony eMMC in TVs

Sony LCD/LED TVs store their operating system and unique security data inside an eMMC chip (embedded MultiMediaCard).
The data is divided into partitions:

Partition	Purpose	Notes
BOOT1 / BOOT2	Bootloader, minimal firmware	Needed for CPU to start reading OS
User Area (USER)	Main OS, apps, Android system	Can be replaced from donor dump
TA / DRV / SECURE	Security keys, panel config, DRM	Must be kept from original board to avoid losing functions
MISC	Calibration, region settings	Match to panel

---

2️⃣ Why Simple eMMC Swap Fails

• Board-locked keys: BOOT partitions have encryption tied to the CPU.

• Different panel configs: Wrong LVDS/eDP mapping causes no picture.

• Security partitions missing → loss of Netflix, YouTube, or OS boot failure.

---

3️⃣ Recovery Methods

Method A — Safe Clone (Preferred)

When: Original eMMC is healthy enough to read.

Tools: RT809H, EasyJTAG, UFI, or similar.

Steps:

1. Backup Original Chip

   • Connect to original faulty board’s eMMC via ISP pinout.

   • Read FULL dump (BOOT1, BOOT2, USER, EXT_CSD).

   • Save in at least 2 locations.

2. Read Donor Dump

   • Get a full dump from a working identical board.

3. Merge Files

   • Keep SECURE/DRM/TA partitions from the original.

   • Replace SYSTEM/APP partitions from donor.

4. Write Back

   • Program merged dump into original chip or a new eMMC.

---

Method B — Direct Donor Write (Keys Lost)

When: Keys not important (TV used offline or without DRM).

1. Program donor’s full dump to new eMMC.

2. Install on faulty board.

3. Boot and check — Netflix/DRM will not work unless keys restored.

---

Method C — New Blank eMMC + USB Recovery

When: No dumps available but firmware is online.

1. Fit same-size eMMC (Samsung, Hynix, Kingston).

2. Program minimal BOOT1/BOOT2 (from service files).

3. Enter USB Recovery Mode to install full firmware.

Sony USB Recovery Key Combos:

• Android Models:

  • TV OFF → Hold Vol– & Power on TV → Plug in power → Hold until LED blinks amber/white.

• Linux Models:

  • TV OFF → Hold OK button on remote → Power on → Wait for firmware load.

4️⃣ eMMC Pinout (Sony Android TV Example)

Most Sony Android TVs use BGA153 or BGA169 packages.
Typical ISP points:

CMD  → Test pad near CPU (label "CMD" or "C")
CLK  → Test pad near CPU (label "CLK" or "CK")
DAT0 → Test pad near CPU (label "D0")
VCC  → 3.3V rail
VCCQ → 1.8V rail
GND  → Ground pad

⚠ Always confirm with board schematic or multimeter before soldering.

5️⃣ Partition Map (Sony Android TV Example)

BOOT1        4MB
BOOT2        4MB
RPMB         4MB
system_a     ~1.2GB
system_b     ~1.2GB
userdata     varies
vendor       300–500MB
ta           2–8MB
misc         1MB

💡 Keep ta from original board at all costs.

6️⃣ Health Testing Before Programming

Using programmer software:

• Read EXT_CSD — Check life time estimation values.

  • 0x0A = New, 0x0B–0x0C = Medium wear, 0x0D+ = End of life.

• If many bad blocks in boot area → replace eMMC.

---

7️⃣ After Repair

• Run TV → Do factory reset via service menu.

• If panel config is wrong → set correct panel type in Service Menu:

  • Enter service mode: Display + 5 + Vol+ + Power on remote.

---

8️⃣ Common Problems After eMMC Work

Symptom	Likely Cause	Fix
TV boots but no picture	Wrong panel config	Set correct panel in service menu
TV boots to logo loop	Corrupt system partition	Reflash USER area
Netflix/YouTube error	Lost DRM keys	Restore TA/SECURE partition
TV doesn’t turn on at all	Missing BOOT1/BOOT2 or dead CPU	Reprogram bootloader / check SoC

---

9️⃣ Example Workflow (Technician Short Version)

1. Read original chip fully (save dump).

2. Test eMMC health — replace if bad.

3. Get donor dump for exact model.

4. Merge donor system + original security partitions.

5. Write merged dump to chip.

6. Reinstall chip & test.

7. Final firmware update via USB for stability.
