would you suggest replacing the resistor that goes to the 12v on? Because the only board i found that was reasonably priced sub $200usd was ver 1.4 and mine is a 1.1 there were some differences between the two.

Answer this question I have this problem too

No. 18 12v on has no power everything else is ok

That is your power on so looks like you are having issues with the power board.

Do you have power before and after R2322? If so then you should not have to. If you do not, then you will have to check around Q2301

@slyver11 sounds like a board issues. the very first thing you want to do is to follow the flowchart for the “No Power” situation. Measure the voltages as shown. Let us know what you find.
