Identification 101 (And Why It Matters!)

So you’re ready to replace a TV board – awesome! 🙌 But before you dive into your DIY repair project, there’s one crucial step you can’t skip: getting the correct part number. We see it all the time — ordering based on the board number instead of the part number leads to mismatched parts, wasted time, and unnecessary frustration. 😤

That’s why we’ve put together this handy guide to identifying part numbers for the four major brands we work with the most at TVpartsToday: Samsung, Vizio, LG, and Sony. Knowing exactly what to look for can make all the difference between a smooth DIY fix and a repair headache.

Let’s break it down by brand — with real tips, real formats, and real DIY confidence.

🔍 Samsung: The Easiest to Identify

Samsung has the most consistent labeling format, making part number hunting a breeze.

• Main Boards: Look for a white sticker with a part number that starts with BN94-XXXXX or BN96-XXXXX.
  

• Power Supply Boards: Typically start with BN44-XXXXX.
  

• T-Con Boards: Most start with BN95-XXXXX or BN96-XXXXX.

⚠️ Watch Out! Samsung boards also list board numbers like BN97-XXXXX, which should NOT be used to order parts. Always go with the part number instead.

💡 TVpartsToday Tip:
If you're unsure whether you're looking at a board number or a part number, snap a picture and send it to us! We’ll confirm it for you, no pressure, no guesswork.

🔍 Vizio: More Variation, But We’ve Got You

Vizio part numbers are a bit trickier, but totally doable with the right know-how.

• Main Boards: Look for a sticker with a partial number like GXICB02K039 and convert it to the full part number by adding 756T to the front.
  

• Power Supply Boards: Start with ADTV (e.g., ADTVN5714AAX).
  

• T-Con Boards: These vary widely in style and number format — so don’t hesitate to reach out if you’re not sure what you’re looking at.
  
  

💡 TVpartsToday Tip:
 We decode Vizio numbers every day! Just shoot us an email or call us and we’ll walk you through it — no judgment, just help.

🔍 LG: Keep an Eye on the Prefixes

LG uses a few different prefixes, and it’s easy to get tripped up by board numbers vs part numbers.

• Main Boards: Look for a sticker with EBTXXXXX — this is your part number. Sometimes LG switches it up and uses EBR or EBU as the prefix, but this is less common.
  

• Power Supply Boards: Your target is EAYXXXXX.
  

• T-Con Boards: Usually begin with 6871L-XXXXX, but the “6871L” won’t always be printed — you’ll need to add it manually before searching.
  

⚠️ Don't Use: Numbers starting with EAX — these are board numbers, not part numbers!

💡 TVpartsToday Tip:
 Print looking fuzzy or hard to read? Snap a pic in good lighting and we’ll help you sort it out — fast.

🔍 Sony: The Trickiest of the Bunch

Sony likes to keep things interesting. 😉 Their main board part numbers often aren’t printed on the board at all!

• Main Boards: Use the number on the white sticker to search on TVpartsToday.com — we’ve built a database to match those numbers to actual part numbers. It should look like: AXXXXXXXA, or perhaps A-XXXX-XXX-A.
  
  

• Power Supply Boards: Much easier! Look for a 9-digit number (sometimes with dashes) printed on a white sticker. For example, 1-010-150-11.
  
  

• T-Con Boards: Often follow formats like 6871L-XXXXX or LJ94-XXXXX, similar to other brands — but beware: Sony may use internal part numbers, too.
  
  

💡 TVpartsToday Tip:
 When in doubt, trust our part matching system. Just enter the number from your sticker into our search bar and let our database do the work for you.

🧠 Final Thoughts: Precision Matters in DIY Repairs

There are literally thousands of part number variations out there, and some can look deceptively similar across brands. That’s especially true for t-con boards! So always double-check your part number before you hit that “Buy” button.
