标题:

Anyone know what the power supply output voltages should be?

文本:

The first LED lights up, the second seems a little dim; (both fans start slowly,) the third never lights, (with display & inverter cables plugged back in.)

Of the five wires from the power supply to what I think is the inverter board? brn, blk, blk, brn, brn, only the last two browns show 5.0 Vdc, nothing on the rest. Anyone know if there should be 12V maybe on that first brown wire? Don't most computers need both 12V & 5V?

Checked PS caps carefully, no obvious signs of overheating or leakage.
