Important Identification: Match BN94-03970E / BN41-01378A with the original board before purchase
Compatibility Check: Always compare the complete BN94 part number, BN41 number, panel number, connectors, board revision and component layout with the original PCB

Verified Compatibility: BN94-03970E / BN41-01378A is documented for the Samsung UE40C5100QW platform, which is the closely related C5100 version of the requested UE40C5105QW.
C5105 Variant: The UE40C5105QW is a regional variant within the same Samsung C5100/C5105 platform, so the exact TV suffix and original PCB label should be checked before purchase.
Board Identification: BN41-01378A identifies the PCB family, while BN94-03970E identifies the specific populated main-board assembly.
Related Models: BN94-03970E is documented for Samsung UE40C5100QW and related C-series configurations.
Board Variations: The BN41-01378A PCB family is also used with other BN94 assemblies, including BN94-02758B, BN94-03368A/B/C/Y and BN94-03970E. Therefore, BN41-01378A alone is not sufficient for exact compatibility.
Panel Matching: The T400FAE2-HE / CY-T400FAE2HEE panel marking should be compared with the original TV because panel configuration can affect mainboard compatibility.
Firmware Compatibility: The main board contains model-, region- and panel-specific software/configuration, so matching the complete BN94 assembly is strongly recommended
Connector Matching: All LVDS/display, power, tuner, speaker, control and peripheral connectors should match the original board
Board Revision: Check the exact revision and barcode information printed on the original PCB before installation
Replacement Note: Do not select the board solely by the BN41 number; BN94-03970E and the panel configuration provide a more precise identification
Installation: Professional installation is recommended
