Sony Firmware Update Help

IMPORTANT: Try the replacement Sony main board in your set before attempting the firmware update; a small percentage of boards will not require the update, and performing the update incorrectly will brick the board.

After installing the mainboard in your set, expect the television to have a blank screen and your power indicator light may or may not be flashing an alternating green/amber, white/green, red/white. This indicates the mainboard is functioning properly and the TV is expecting the firmware update. The firmware will be updated using a USB FLASH DRIVE. 

YOU WILL NOT POWER ON THE TV FIRST. YOU CAN PERFORM THE FIRMWARE UPDATE EVEN IF THE TV DOES NOT APPEAR TO POWER ON.

Reminder: You will not see anything on the screen. 

You MUST perform the USB firmware update without an image on your television. 

• Confirm you are using the USB thumb drive that was shipped with your part; if you did not receive a thumb drive with your part, be sure you have a thumb drive that is 4GB or LESS!!! The firmware will not take with a larger thumb drive.

• Find and download the latest firmware for your television on the Sony website.   https://www.sony.com/electronics/support
