• No backlight or image

• Stuck on Sharp logo

In such cases, rewriting the NAND memory with a verified dump can often resolve the issue completely.

Mainboard and Memory Specifications

🔧 Mainboard: QPWBXF455WJZZ

This mainboard is responsible for handling all logic, processing, and connectivity in the LC-40LE810E. It integrates the tuner, input-output ports, video processing unit, and NAND memory controller.

💾 NAND Flash: Samsung K9F1208U0C

This is a 128Mb (16MB) SLC NAND flash chip where the bootloader, firmware, and system files are stored. If corrupted, the TV cannot boot or operate properly.

How to Flash NAND Memory on SHARP LC-40LE810E

To repair the TV, you’ll need to download the NAND dump and use a NAND programmer to write it to the K9F1208U0C chip.

Required Tools:

• Verified NAND dump firmware file

• TSOP48 adapter compatible with the K9F1208U0C

• NAND flash programmer (e.g., RT809H, TNM5000, TL866II Plus with TSOP48 adapter)

• Hot air rework station or soldering iron (if chip removal is necessary)

Flashing Steps:

1. Backup the Original NAND (if possible):
   Before writing, try to read and save the current contents of the NAND to preserve any unique calibration data.

2. Erase and Program:
   Use your programmer software to fully erase the chip and write the new firmware dump.

3. Verify After Writing:
   Always verify the written data against the source dump to ensure no errors.

4. Reinstall NAND (if removed):
   Solder the NAND chip back to the board or place it into the socket if using an in-circuit programmer.

5. Power On and Test:
   Reassemble the TV, plug in, and power on. If the process is successful, the TV should boot normally.
