If you are taking on a DIY repair for your LG television, there is one rule that matters more than anything else. Always use the part number and never rely on the board number. It may seem like a small detail, but this single step determines whether your repair works the first time or turns into a frustrating cycle of returns and delays.
At TVpartsToday, The World's #1 Hub for DIY TV Repair, we have seen how often this mistake happens. LG televisions in particular are known for displaying multiple numbers on each board, which can make identification confusing if you do not know what to look for. Once you understand how LG labels their parts, the process becomes much more straightforward.
If you prefer a visual guide, our Identification 101 video walks through these steps in detail and can help reinforce what you are looking for on your specific board. You can watch it below:
Why Part Numbers Matter More Than Board Numbers
Every board inside your LG TV will have several numbers printed on it. Some of these are used during manufacturing, while others are used for ordering replacements.
The part number is the only number that guarantees compatibility with your specific television. This number is typically found on a white barcode sticker or printed clearly on the board itself.
Board numbers, often labeled with prefixes like EAX, are used internally by LG during production and testing. These numbers may appear similar to part numbers, but they are not reliable for ordering. Multiple boards can share the same board number while having different internal configurations.
Relying on a board number can result in receiving a part that looks correct but does not function properly once installed.
TVpartsToday Tip: If you are unsure which number is correct, take a clear photo of your board and send it to our team. We will confirm the exact part number for you before you order.
Identifying LG Power Supply Part Numbers
The power supply board is responsible for distributing voltage throughout your television. When it fails, you may experience issues such as no power, intermittent shutdowns, or a blinking standby light.
LG power supply part numbers typically begin with the prefix EAY followed by a series of digits. This number may be printed directly on the board or located on a white barcode sticker.
In some cases, the EAY prefix may not be printed on the sticker, but the remaining digits still correspond to the correct part number when combined with the proper prefix.
It is important to ignore numbers that begin with EAX, as these are board numbers and not suitable for ordering replacements.
Identifying LG Main Board Part Numbers
The main board controls nearly every function of your TV, including video processing, audio output, and input recognition. If your TV has issues with HDMI ports, freezes during operation, or fails to respond to the remote, the main board is often the component to inspect.
LG main board part numbers usually begin with prefixes such as EBT, EBR, or EBU, followed by a series of digits. These numbers are most commonly found on a white label attached to the board.
While many main boards may appear identical, even small differences in part numbers can indicate different firmware or hardware configurations. Matching the exact number is essential for proper functionality.
Identifying LG T Con Board Part Numbers
The T Con board is responsible for controlling how image data is sent to the display panel. When this board fails, you may see symptoms such as lines on the screen, distorted colors, flickering, or a complete loss of picture.
LG T Con part numbers typically begin with the prefix 6871L followed by a combination of numbers and letters. In some cases, only a portion of the number may be visible on the board.
If you only see the suffix printed, you may need to reconstruct the full part number by adding the 6871L prefix. This step is important when searching for a replacement.
Because these numbers are often printed in small text, careful inspection is necessary to ensure accuracy.
TVpartsToday Tip: Use good lighting and take your time when locating T Con numbers. If the number is difficult to read, a clear photo can help confirm the correct part.
Accuracy Is the Key to a Successful Repair
When your TV is not working, it is tempting to move quickly and order a replacement part based on appearance or partial information. However, taking the time to verify the exact part number is what ensures a successful repair.
Even boards that look identical can have subtle differences that affect compatibility. Matching the correct part number eliminates this uncertainty and allows you to complete your repair with confidence.
If you are unable to locate the part number or want confirmation before ordering, our team is always available to assist. A quick verification can save significant time and prevent unnecessary returns.
