Important Identification: Match BN44-00353A / PD46AF0E_ZSM / PSLF121B01A-B with the original power supply board before purchase
Compatibility Check: Always compare the complete BN44 number, PD46AF0E_ZSM marking, PSLF121 revision, connectors and PCB layout with the original PSU
Verified Compatibility: BN44-00353A / PD46AF0E_ZSM is documented for the Samsung UE40C5100 platform, which is the same C5100/C5105 family as the requested UE40C5105QW.
Samsung Board Identification: Samsung documentation identifies BN44-00353A as a DC VSS-LED TV power board, with the board designation PD46AF0E_ZSM and PSLF121 platform.
Board Variants: The BN44-00353A family is associated with PSLF121B01A/B, and documented revisions include REV 1.3 and REV 1.4. The exact revision should be matched with the original PCB.
Output Rails: Documented board specifications include approximately 5.3V standby, 5.3V and 12.8V operating outputs, with the exact output configuration depending on the board revision.
Integrated LED Driver: The LED backlight driver is integrated into the PSU rather than being a separate power board; service documentation identifies an HV9963-based LED-driver section.
Power Capacity: Samsung parts documentation identifies BN44-00353A as an AC/DC LED-TV power board with approximately 115W rated capacity.
Related Models: BN44-00353A is documented in Samsung UE40C5100, UE46C5100 and related C-series LED televisions.
Panel Compatibility: A documented UE40C5100 configuration uses the LTF400HM02 panel, while other C-series variants can use different panels. Therefore, the original PSU and TV configuration should be matched carefully.
Replacement Note: Do not rely on the TV model or board appearance alone. Match BN44-00353A / PD46AF0E_ZSM / PSLF121B01A-B and the complete original board label before purchase.
Installation: Professional installation is recommended because the board contains mains-voltage circuitry
