BN6924878F: The Samsung TV Code You Shouldn’t Ignore

If you own a Samsung TV, you might have seen a strange code like BN6924878F printed on a sticker or part. Many people think this is the model number of their TV—but it’s not! It’s actually a part number, and it can be very important.

This small code can help you fix your TV, save money, and even avoid buying the wrong replacement parts. In this article, we’re going to explain what BN6924878F means, why it matters, how to find it, and what to do if your TV stops working and needs a repair.

Let’s make it simple, clear, and helpful—so anyone can understand.

What Is BN6924878F?

BN6924878F is not the name of your TV. It’s a part number that Samsung uses to identify one small but important part inside the TV. Usually, this part is a main board or power board.

Think of it like this: your TV is made of many parts—just like a car has different parts like an engine, battery, or tires. The main board is like the brain of the TV. It controls things like the picture, sound, and HDMI ports. If something goes wrong with it, your whole TV can stop working.

So, when technicians open up a TV to repair it, they don’t just look at the outside. They check the part numbers like BN6924878F to know exactly which part needs to be replaced.

Why BN6924878F Is Not a TV Model Number

It’s easy to get confused. When you look at the back of your TV, you might see several codes and numbers. One of them is the model number—that’s the full name of the TV (like UN55NU7100FXZA). This is what you use when buying or searching for your TV model.

But BN6924878F is different. It’s just for one part inside your TV. It doesn’t tell you the screen size or the full TV model. It only tells you the code for a specific board or module.

Here’s a quick example to help:

• Model number: Like the name of a full book.

• Part number (BN6924878F): Like the name of one page in that book.

If your TV has a problem and you give someone the model number, that’s helpful. But if you want to fix a broken part, they’ll also ask for the part number—and that’s where BN6924878F comes in.

What BN6924878F Controls Inside Your TV

So, what exactly does the part labeled BN6924878F do?

In most cases, this code belongs to the main board or motherboard of your Samsung TV. This board is super important. It connects everything together and manages:

• The picture you see on the screen

• The sound that comes from your speakers

• The HDMI and USB ports

• The way your remote talks to the TV

If your TV suddenly stops working, or the screen goes black, or you can’t use your HDMI ports, there’s a good chance something’s wrong with this main board. And when that happens, the part number BN6924878F becomes the key to fixing it.

Where You Can Find BN6924878F on Your Samsung TV

Now you might be wondering: Where can I find this code on my TV?

Here are a few simple ways:

• Check the back of your TV. There’s usually a sticker with several numbers. Look closely—BN6924878F may be printed there, especially near the barcode.

• Look inside the TV (if you’re a technician). The part number is often printed directly on the main board itself. But this requires removing the TV back panel, which should only be done carefully.

• Check the service manual or repair sheet, if you have one. Sometimes these documents list the internal part numbers.

Just remember: don’t mix it up with the model number. The model number is for the whole TV. The part number is for a single part inside.

Why Knowing Your BN6924878F Code Saves Time and Money

Let’s say your Samsung TV stops turning on. A technician tells you the main board is bad. If you don’t know the exact part number, you might:

• Buy the wrong part online

• Waste money on something that doesn’t fit

• Delay the repair

• Or even damage your TV more by installing the wrong part

But if you know your BN6924878F code, you can easily search for that exact part online or give it to a technician. It’s like giving someone the exact puzzle piece they need—instead of asking them to guess.

Many people end up returning parts or spending double just because they didn’t check the part number first. So just by knowing BN6924878F, you’re already one step ahead.

Common TV Problems BN6924878F Can Fix

The BN6924878F part plays a big role in how your TV works. If it gets damaged or stops working, you might see:

• A black screen (even when the TV is on)

• The TV not turning on at all

• No sound or weird buzzing noises

• HDMI ports not detecting anything

• USB ports not working

• The TV freezing or crashing randomly

If your TV is showing any of these signs, the part labeled BN6924878F might be the reason. In many cases, replacing this part fixes the problem completely—as long as it’s diagnosed correctly.

If you notice one or more of these problems, the main board inside your TV might be faulty. That’s where BN6924878F comes in. A trained technician can open your TV and check the board. If that’s the one that’s damaged, you’ll need to replace it with the same exact part.

Never guess. Always check the part number first.
