AC Power Applied AC Det (Pin 18) and 5V STB (Pins 9 ~ 12) are 5V.
100Ω ¼ watt resistor added from 5V STB (Pins 9 ~ 12) to RL ON (Pin 19) closes relay RL101 turning on the 16V Supply
100Ω ¼ watt resistor added from 5V STB (Pins 9 ~ 12) to VS _ON (Pin 20) brings the VA and VS Lines high
100Ω ¼ watt resistor added from 5V STB (Pins 9 ~ 12) to M5V_ ON (Pin 21) brings the 5V VCC line high
Ground the Auto Ground (Pin 22) on P813
