The left audio channel on my player is wonky. Mostly it's silent, but every now and then, there's a bit of static, and I'll get some audio. The higher the volume, the more likely I'll get these occasional blips of audio. My first thought was the loose wiring in the sled loom, but I've now tested two different sleds (one brand new), plus the mlord dock, and the problem exists in all three. The right audio channel is clear as a bell. The RCA connectors on the back of the player do not exhibit the same problem.

I took the player apart, unplugged the loom internally, and checked the continuity of the wiring from the internal to external pins (everything normal).

Any help further diagnosing/fixing the problem would be appreciated.
