When you're diving into a DIY TV repair, you’ve probably heard us say it a thousand times: match your part number exactly. And for good reason — it’s the best way to ensure you’re getting a part that’s fully compatible with your TV model. But what if we told you there’s a small, manufacturer-approved exception to this rule? Welcome to the world of cross compatible parts! 🙌
🔍 What Is a Cross Compatible Part?
A cross compatible part refers to a replacement circuit board that works interchangeably in your TV even though it has a different part number than your original board. These boards are typically manufactured to the same specifications and often feature:
✅ Identical layouts and components
✅ Matching firmware and software
✅ Equivalent electrical and signal capabilities
In essence, they’re functionally identical, just listed under a different manufacturer-assigned part number. Confusing, right? But it doesn’t have to be! Let’s dive into it a little more…

🔧 Why Do Cross Compatible Parts Exist?
TV manufacturers like Samsung, LG, Sony, and Vizio sometimes assign different part numbers to boards that are, for all intents and purposes, the same. Why? Here are a few reasons:
🔄 Minor design tweaks: The layout or component brand might change slightly, but the board still performs identically.
🌍 Regional production differences: One batch might be made in Korea and another in Mexico, using slightly different labeling.
📦 Updated firmware: A newer part may simply come pre-flashed with updated firmware that doesn’t impact compatibility.
For example:
🧩 Samsung Main Board BN94-15565F is fully interchangeable with BN94-16105R — the manufacturer has confirmed this on their website. These two boards work exactly the same and can be swapped without issue. (Pictures of parts below)
⚠️ Proceed With Caution: Don’t Assume Compatibility
TVpartsToday Tip:
Only use a cross compatible part if it’s been explicitly confirmed by the manufacturer or a trusted supplier like us. Just because two boards look similar — or even identical — doesn’t mean they’ll work the same. Small variations in components or firmware can result in major malfunctions. 😬
That’s why we always recommend ordering by your exact part number when shopping our website. Unless you're 100% sure a board is a verified cross match, don’t take the risk!

Final Thoughts
Cross compatible parts are one of the few exceptions to the part-number-only rule — but they’re the exception, not the norm. So unless a source like TVpartsToday or the manufacturer’s own database has confirmed it, stick with an exact part number match every time.
Because when it comes to TV repair, getting it right the first time saves time, money, and stress.
✨ And remember: If a cross compatible part worked for someone else — it could work for you too.
But if you're ever unsure, we're only a call or click away.
