Frequently Asked Questions (FAQ). Q: How do I make sure this mainboard is compatible with my TV? A: Do NOT match by TV model number alone. TV manufacturers often use different mainboards for the exact same TV model depending on the screen panel or production date. Always match the exact Part Number from the sticker on your original board e. Samsung BN94-xxxxx, LG EAX/EAYxxxx, Sony A-xxxx-xxx-A. Q: The part number sticker is too small and I can’t read the numbers. What should I do? A: The text on PCB barcode stickers can be very tiny! We recommend using a handheld magnifying glass or taking a clear, close-up photo with your smartphone camera and zooming in on the image. Can you help me diagnose the problem? TV repair involves high-voltage components and complex troubleshooting. If you are uncertain about the cause of the failure, we strongly advise consulting a qualified local TV technician. DIY repairs are not recommended for non-professionals. Q: The board I received looks identical to mine, but the part number is off by one letter/digit. A different revision letter or digit often means the board is programmed for a different panel resolution, screen size, or power configuration. Installing an incorrect board may result in a distorted picture, flipped screen, or no display at all. We are happy to assist with troubleshooting or providing a replacement! Please match the PART NUMBER exactly before ordering. TV model numbers alone are NOT enough to guarantee compatibility. Many TV models use multiple board versions and panel combinations. This board was professionally removed from a fully functional New TV with a cracked or damaged screen. All parts are tested and guaranteed working prior to removal.
