T.sk105a.03 - Schematic Diagram

T.SK105A.03 is a versatile universal LCD/LED TV controller driver board used primarily for reviving older displays or building custom monitors from 15 to 42 inches. Because it is a "universal" board, it can replace difficult-to-find original motherboards in brands like TCL and Skyworth.

3.2 Components (Symbols per ANSI/IEEE or DIN standard)

• Semiconductors: Diodes (1N4007 type), bipolar transistors (2SC, 2SA series), possibly early op-amps or vertical deflection IC (e.g., AN5515 or TDA1170).
• Passive: Carbon film resistors (color-coded value or printed), ceramic/electrolytic capacitors, potentiometers (labeled VR1, VR2).
• Magnetic components: Flyback transformer (FBT) in CRT designs, mains transformer, deflection yoke coils.
• Connectors: CN101, CN102 – often with pin functions (AC in, video out, ground).

The board architecture is designed for "basic type" ATV (Analog TV) sets and features several critical hardware jumpers and ports as noted in technical documentation from Elecbee and Scribd: T.sk105a.03 Schematic Diagram
