V1.0 Board With No Audio
Posted 24 May 2010 - 02:27 AM
I know my cables are good.
I know the AVIP port is good (continuity from red and white plugs to avip pins on bottom of board good).
I know my TV is good
I did a little research online and found that apparently, the xbox 360 has lots of sound issues.
I vaguely remember a post here about a sound issue and the O.P. had to replace a transistor but I think that issue was regarding a 1.6.
Also, I know the xbox supports DTS but if memory serves correctly, the analog audio signal could not be disabled via MS Dash, but even so having no HD connected, I don't see how such a setting would stick.
Any ideas? Thoughts? Opinions?
If I can't revive the board, I can always use the ram I guess.

Some HD A/V cables and 3rd party cables didn't always work.

For future reference, This is what I did.
Near pinhole 15 of the LPC on the bottom of the motherboard, there are 2 traces that run directly next to this hole. The trace closest to the pinhole had been severed in a botched modchip removal/installation attempt.
I soldered a wire from point "A" to point "B" and the sound works.
The weird part of the whole thing is that pins 1 through 6 still had the factory applied solder. Pins 7 through 16 were the holes that had been tampered with. Maybe a sloppy repair by MS? Or maybe a case of someone who knew absolutely nothing about nothing trying his/her luck at installing a chip? I dunno. It's fixed anyway.
The trace closest to the pinhole was severed.
