If "TSK105A03" is printed on the actual circuit board (e.g., a green PCB in a TV) rather than on a small black chip, you are looking for a TV Service Manual.
The T.SK105A.03 Go to product viewer dialog for this item. is a popular universal LCD/LED TV controller driver board primarily used to repair or repurpose old monitors and television panels. While full technical schematics are often protected by manufacturers, related technical documents like pinout specifications and service manuals are available. Technical Overview
This board acts as a "central nervous system" for custom or repaired TVs, converting various signals into the specific timing and voltage required by an LCD panel.
Supported Input: HDMI, VGA, USB, TV (Analog only), and PC-RGB. Resolution: Supports up to Full HD (1920x1080) at 60Hz. tsk105a03 schematic diagram free
Panel Voltage: Flexible options for 3.3V, 5V, or 12V DC power supply to the panel. Audio Output: 2x3W (4Ω) max output power. Schematic and Service Documentation

Sometimes a paper schematic doesn't exist for free, but a video trace does. Search YouTube for your board number. Many repair vloggers will show the voltage rails and signal paths going into the TSK105A03, effectively giving you a "visual schematic" for free.
Before diving into the schematic, let's understand what this IC does. The TSK105A03 is a current-mode PWM (Pulse Width Modulation) controller with an integrated high-voltage MOSFET. It is part of a family of power ICs designed for flyback converter topologies.
Websites like Reddit (r/LearnElectronics, r/Electronics), Stack Exchange (Electrical Engineering), or specific forums dedicated to electronics and DIY projects can be incredibly helpful. You might find threads discussing similar components or direct links to schematics.
Many engineers don't realize that the official datasheet for the TSK105A03 (from manufacturers like Toshiba, or its generic equivalents) contains a complete reference schematic. Search for: TSK105A03 datasheet PDF. Inside, look for "Application Circuit" or "Typical Connection Diagram."
