I recently tried watching a DVD and realized that there was no audio. I switched over to Analog output, and I got audio through my HDMI Audio Extractor headphone amp. Once I was done watching tough, I noticed some 60-cycle hum and went, "Oh god, NO." I use this thing to listen to 1400Mbps music and a low noise floor is pretty much essential. I switched it back to digital output, but the hum persists. XBMC is the ONLY application doing this. the MS Dash is completely fucking silent and the music sounds nice and clean through it... like how my XBMC installation did before I screwed around with it all day. I believe XBMC is not outputting digital properly somehow and everything else IS. I have a Pound converter handling the encoding of analog and digital into the HDMI signal. Any ideas, guys?

Hi, I'm trying to repair my xbox v1.6 with a Delta 220v PSU because it doesn't power on at all(even the fan isn't spinning). Backstory: the xbox stopped working all of a sudden(it worked just the day before even with the leaked/bulging caps), so thinking that maybe the power and eject buttons got broken, I tried to turn it on by shorting the SW1 Eject or SW2 Power(I can't remember which) to GND according to this diagram of the front panel connector. I don't think this was a good idea since the xbox didn't turn on and I heard a small spark but I'm not totally sure. Now from the PSU, not plugged into the motherboard(so in stand-by I guess), I get a ~5v reading from the orange wires but 0.1v from the blue wire(which should be 3.3v even on stand-by according to this table) and ~0 volts from the other 3.3v and 12v rail as it should be. Moving on to the motherboard, after removing all the bad capacitors, I still get a short between the 5v rail and ground(measuring the pins of psu connector on the motherboard). I also tried measuring the caps under the CPU(starting from C2P1 to C2P17) and they're all shorted to ground. The caps C2E2 and C1E1 too. Also, measuring the VRM(?) FAN5059M I'm getting a short on the pins(apart from GND) 2_SW, 6_VID2, 8_VID0, 20_VFP. All this leds me to believe that the CPU is fried but I can't really wrap my head around how I could have done that, is there something I'm missing/misunderstanding?
