In this video, I walk you through my repair of a Roku TV model 100012587 that looked like a classic backlight failure. The screen was dark, the symptoms pointed to LEDs… but the real problem was hiding on the power supply board.

While disassembling the TV and checking the LED strips, I discovered a bloated capacitor that was causing the entire backlight circuit to fail. I highlight the exact capacitor in the video, explain what to look for, and show how a simple component replacement can bring your TV back to life.
