Kenmore Elite won't power on

Dishwasher will not power on. No lights are on. There’s power to the unit. I’ve checked the thermal fuse and door switch. They are fine. I’m getting 120v to the P8(Tan) and P2-6(BK-W) to the return P7 (W-V) wires. I’ve also jumpered around the fuse and door switch. Still no lights. I’ve replaced the control board. I have the same problem, no lights. Is there something else to check ? Is there a more detailed service manual available?
What’s the voltage applied to light the LEDs?

Thanks for the help.

Is there other checks possible?
Will a bad thermistor cause the unit not to power on\no lights?
