- I need to get a hold of A4000 schematics to fix a recent audio problem.
- The left audio channel is garbled - but the right works fine. The
- problem was intermittent for a while (as if a part was failing) and
- now it is here to stay. It is extremely difficult to diagnose since
- several things measure a dead short with no power applied. Even the
- two audio outputs measure shorted together!? Any ideas on what might
- be causing the problem?
-
- Where can I get the schematics for the A4000, and how much do they
- cost? Or... could some kind soul send me just the schematic for the
- audio output section? I desperately want to get this fixed ASAP.
-
- BTW: My A4000 has always exhibited an odd behavior with the audio
- output. If I connect an amplifier to just the left (white) output,
- I hear the right audio channel. If I connect just the right (red)
- output, I hear the left audio channel. When I connect both outputs,
- the channels reverse - left is left, right is right. Is this
- behavior normal, or has this been defective from the start?
