Emax

I don't even know what meter your referring to. I'm capable of resoldering the two cold joints and reconnecting the psu. Is this that risky? Sigh. I feel like I should ask the seller for a partial refund since it isn't working and I bought the machine in what was supposed to have been working condition.

I am not a tech, but my advice to you is to keep the power supply unplugged from the mainboard until you can confirm with a meter that it is outputitng the right voltages on the right lines.  It's easy to replace a power supply, but not an e-chip.
