Look for a short to ground on VCC_MAIN, usually the capacitor on the back of the board near the top left corner.

What did you change? Did you have a short on VCC_MAIN?

L9 is an inductor it should measure 0 ohm if good. Don't mistake it for a short. Bad inductor coils measure open

You need to find shorted capacitor or ic on vcc_main
