Technical PDF on boosting power supplies, 2.24 MB, filed among schematics. The name points to step-up (boost) converter topology rather than a particular TV or board, and no model number is given. Boost stages are common in LED TV backlight drivers and PFC sections, so a reference like this helps explain how the inductor, switching MOSFET, diode and feedback divider work together. Use it to understand typical failure points such as shorted MOSFETs, open diodes or dried capacitors before measuring a real board.
