MICROMAX POWER SUPPLY BOARD MODEL NUMBER 43E9999UHD The image displays a power supply board, which is a crucial component in electronic devices like televisions, responsible for converting incoming AC power into various DC voltages required by the device's other circuits.  Key details visible on the board: Primary Side: This section, labeled "Primary," handles the high-voltage AC input from the mains power. It includes components like the main input connector, fuses (indicated by "CAUTION FOR CONTINUED PROTECTION AGAINST RISK OF FIRE REPLACE ONLY WITH SAME TYPE AND RATING OF FUSE"), large capacitors, and the primary winding of the main transformer. Secondary Side: Labeled "Secondary," this section deals with the lower DC voltages generated after rectification and regulation from the primary side. It contains components such as output capacitors, diodes, and connectors for delivering power to other parts of the device. Transformers and Inductors: Several yellow-taped transformers and copper-wound inductors are visible, indicating voltage conversion and filtering stages. Capacitors: Various electrolytic and ceramic capacitors are present, used for filtering, smoothing, and energy storage. Heat Sinks: A prominent black heat sink on the primary side and a smaller silver heat sink on the secondary side are present, indicating the presence of power transistors or ICs that dissipate heat during operation. Connectors and Mountings: The board features various connectors for input power and output to other boards, as well as mounting holes for securing it within a device. Labels and Markings: The board includes numerous labels for components (e.g., C301, R210, D501), test points, and safety warnings, aiding in identification and troubleshooting. 

The image displays an SMPS (Switched-Mode Power Supply) board, identified as the "ONIDA 43 FIF POWER SUPPLY BOARD" based on the query and search results. This board is a crucial component in LED TVs, specifically in Onida 43-inch models like the "43 FIF". Details of the SMPS Board: Function: This board is responsible for converting the incoming AC power from the mains to regulated DC power supplies required by various components of the TV, such as the main board, LED backlight, and other internal circuits. Key Components: The board features various electronic components typical of an SMPS, including: Transformers: Large yellow and brown components that are central to power conversion. Capacitors: Cylindrical components (blue, grey, black) for energy storage and filtering. Heat Sinks: Black finned components designed to dissipate heat from power-intensive parts like integrated circuits or transistors. Connectors: White multi-pin connectors for connecting to other parts of the TV, such as the main board or LED strips. Part Numbers/Markings: The board exhibits various markings, including "SYE02612-L250uA 1.0" and "PW.108W2.801", which are likely board revision numbers or part numbers. Designated Areas: The board also clearly labels "HOT" and "COLD" sections, indicating the isolation barrier between the primary (high voltage) and secondary (low voltage) sides for safety and functiona
