A software update is required upon installing this part. After replacing this board please Visit Sony Support and follow the software update instructions below.

Software Update Instructions:
- Download the correct firmware for your model from Sony.
- Format a flash drive to Fat 32
- Extract the firmware to the flash drive. Check the instructions as most firmware needs the  folder to be extracted to the flash drive with the file inside it. It will not work if you just extract   the bin file only.
- With power disconnected insert the thumb drive.
- Plug in power and wait. If the TV stays on standby hit the power button, if it goes to amber   and green let it run
- Wait! Give the TV 10 minutes, if the update works   the light will change to Amber and Red. The TV will reboot several times during the install. Wait   until the onscreen display tells you to remove the flash drive.
- If the install does not work unplug power and flash drive. Turn on the TV and then try inserting  the flash drive again.

What is a main board?

The main board is basically the “brains” of your TV and controls everything, from the audio to video streams. All of the user data and settings are also stored on the main board.

Which symptoms does a main board fix in a TV?

• If your TV doesn’t turn on, it could be the main board. If your TV turns on but has no video and/or no audio, it could also be the main board.

• If one HDMI input works but others don’t work, it could be the main board.

*These are helpful tips to get you started and don’t represent accurate diagnoses for every TV model and failure. If you’re unsure of your diagnosis, we recommend checking out our YouTube channel or reaching out to a local TV technician for assistance.

How easy is it to replace a main board?

It's easy! Once you match the part number on your main board with the part number listed on this page to confirm compatibility, you’ll just need a screwdriver and the ability to remove the back of your TV and replace the board.
