He soldered off the bridge, replaced the supervisor with a fresh part, and reflowed the suspect resistor network. Then he plugged in the TV. The backlight flickered once, twice, then bloomed into steady white. The logo appeared. The hum vanished.

He downloaded it. The PDF was clean—scanned from an original engineering document. He scrolled past the title block, past the revision history, and landed on sheet two. There it was: the SOT-23-5 supervisor. The datasheet callout: RT9202. The correct resistor divider values.
