Why the Exact TV Part Number Matters
One of the easiest ways to order the wrong TV board is to shop from the TV model number or the largest number printed directly on the circuit board. Manufacturers can use several different board versions during the production run of one television model. Boards may look almost identical while using different firmware, tuners, connectors, panel configurations, or component revisions.
For the best match, identify the assembly or service part number from the original component and compare the entire number with the replacement listing.
Step 1: Record the Complete TV Model Number
Find the manufacturer's label on the rear of the television and photograph it. Record the complete model number, including suffixes. Do not shorten it. The model is useful for compatibility research, but it should not automatically be treated as proof that every board from that model is interchangeable.
Step 2: Photograph the Original Board Before Removing It
Unplug the TV and safely remove the back cover. Take a clear photo of the entire board and close-up photos of every white barcode sticker, QR label, and printed identifier. These photos are extremely useful if you need help identifying the correct replacement later.
Step 3: Know the Difference Between a Board Number and Part Number
A number printed directly on the PCB can identify the underlying circuit-board design, while the assembly/service number identifies a completed replacement assembly. Several finished assemblies can sometimes share the same basic PCB number. That means a board can physically look correct and still be the wrong replacement.
Samsung TV Part Numbers
Samsung main-board assembly numbers commonly use prefixes such as BN94-, while BN41- numbers are commonly seen as PCB identifiers. When a BN94 number is present on the original main-board assembly, compare the complete BN94 number first when shopping for the replacement.
Samsung uses other numbering formats for other assemblies, so never choose a part from the prefix alone.
LG TV Part Numbers
LG boards commonly show EAX identifiers as well as assembly/service numbers using prefixes such as EBT, EBR, and EAY. The EAX number is useful for research, but it does not always identify the exact completed assembly needed for your TV. Compare the assembly/service number and the full TV model information whenever possible.
Vizio TV Part Numbers
Vizio replacement boards often use assembly identifiers beginning with 756TX or similar formats. Compare every character in the complete number. Vizio compatibility can also depend on the TV serial-number range, so keep a photo of the rear model/serial label available when shopping.
Sony TV Part Numbers
Sony boards commonly use white identification labels with assembly/service numbers that can differ from numbers printed directly on the PCB. We have a dedicated Sony guide showing the identification process in more detail.

Do Not Rely on Appearance Alone
Matching connectors, component placement, and board layout is a useful secondary check, but appearance should not replace part-number verification. Boards made from the same PCB can look nearly identical while being programmed or populated differently.
TV Part Ordering Checklist
- Record the complete TV model number and suffix.
- Photograph the entire original board before removing it.
- Photograph every sticker, barcode, and QR label.
- Identify the assembly/service part number when available.
- Compare the complete part number with the replacement listing.
- Compare connectors and board layout as a secondary check.
- Review compatible-model and serial-number information.
- If the numbers do not match exactly, ask before assuming compatibility.
Still Unsure? Let Us Help Verify It
Send us a clear photo of the board and its labels along with the complete TV model number. Our team can help identify which number you should be searching before you place the order.
Why Short Circuit Solution Listings Include Multiple Numbers
Our listings can include the primary part number, additional board numbers, and compatible TV models. This helps customers find the product from the different identifiers printed on their original component while still keeping the exact replacement part number clear.
Our used tested TV parts are backed by our 180-Day Warranty.
