TPD.T950X.PB791 Motherboard Stuck in Standby Fix

In this video, I show you how to fix a common standby problem on the Mi TV motherboard TPD.T950X.PB791 (also applies to TPD.T962SX.PB795). If your TV is stuck with a red indicator light and won't turn on even after pressing the power switch, this step-by-step repair guide is for you. We'll walk through the entire diagnostic process, checking critical voltage points: 3.3V Standby & 2.5V DDR Power 1.2V RAM Supply 1.0V Core & Android Processor Supplies 1.8V EMMC Voltage I demonstrate a simple modification by grounding the P-channel MOSFET gate to restore the missing 3.3V to the EMMC, which successfully brings the board back to life.
