Hi all,
I'm looking for advice on a BeoSound 9000 Mk3 (Type 2571) with an intermittent CD problem.
<h3>Background</h3>
The original optical pickup was replaced with a new unit from Quickcycle. The replacement part number was verified against the original before installation.
Unfortunately, the symptoms remained largely unchanged after the replacement.
<h3>Symptoms</h3>
- Sometimes CDs start immediately.
- Sometimes the player ends up in PAUSE.
- Sometimes repeated retries eventually succeed.
- Once playback has started, track skipping often works normally.
- Occasionally the system can switch between multiple CDs without issue.
- At other times several CDs fail one after another.
- On at least one occasion the player was playing normally and then stopped abruptly.
- During some failed attempts the disc appears to accelerate to an unusually high speed.
- Passed successfully (TM OK).
- Fails on all CD positions.
- Disc spins up rapidly, then reports an error.
- Position 1 reports error 7.
- Positions 2-6 report error 3.
- Starts the turntable motor.
- Disc appears to rotate at a very high speed.
- Behaves the same as normal playback.
- Usually ends in failure.
- Multiple CD error 3 entries (radial error).
- Multiple CD error 7 entries (subcode error).
- Two APS error 15 entries.
- No CD error 2 (focus error).
- No new CD error 4 (turntable motor error).
- Would you suspect the new pickup, the pickup ribbon cable/connection, PCB41 (servo board), or something else?
- Is a failing TM73 after pickup replacement pointing towards a known issue?
- Has anyone seen a BS9000 that can sometimes play perfectly and then suddenly stop, while producing mainly CD error 3 and 7?
