Hi all,
Just wanted to share a bit information on my recent search for a replacement Laser Assembly for my Sony SCD-XA9000ES.
I was able to find a replacement KHM-230AAA transport on ebay, the item was Under $50 dollars and was sourced from China, shipped from Florida.
After installing the new Assembly I inserted a disc, right away something was wrong, the clamp would not fully hold on to the CD. After opening the player I noticed that the Spindle HUB on the new unit was of a smaller Diameter and also had four holes around the hub (used to access screws that held spindle motor to the assembly.
The original Spindle Hub is larger in Diameter and had no holes, plus the original has a silver metal ring a the center of the hub that is magnetic and helps clamp hold the CD.
Now the picture on ebay did show the correct Spindle Hub, but the unit shipped to me had the smaller one.
I solved this issue by just taking the New Laser and sled parts and transferring them to the old Assembly which contains the motor and spindle hub.
I don't know if I could have just pulled off the spindle hub from the original unit, I didn't want to risk breaking the original hub.
In the end my SCD-XA9000ES is up and running again with no issues and now recognizes any CD/SACD I feed it.
I hope this helps others that were in my need of a new KHM-230AAA, most of the official Sony sites price this item at over $200 dollars.
Motospark.

Thanks CR,
Always willing to share with the Community.
Oh another note, I did not have to do any adjustments to the replacement, it was plug and play.
One other hint, when replacing the ribbon cable attach it to the laser Head assembly, then to the logic board.
Also there is a blob of solder that also needs to be removed from the Laser Head assembly, without removing it the unit will not work. But this topic has been addressed in other posts I have seen in other forums. Here is the link of where the blob of solder is, it is simply removed with a few inches of solder wick ribbon and soldering iron, and although the instructions are for an older Sony CD/SACD player the Transport is the same model.

Motospark,
You got a new laser from Liberty Electronics in Florida. Any replacement laser you get now is going to be made in China.
I recently had somewhat the same experience as you with a replacement KHM230AAA from Liberty. They do not seem to come with the correct spindle disc head. I did as you did in regards the tracking assembly. However, I learned that you can just pull the spindle head off the spindle and swap disc heads with no damage.
There is also a KHM230ABA replacement laser. These are thought to be the same by vendors. However the spindle disc heads are different and need to be swapped as well.
If you buy a KHM230AAA from Supermanmeliu in Taiwan you will get the correct disc spindle head.

stvnharr,
Your are correct, it was purchased from Liberty. I have emailed them with the information on my findings.
Thanks for your reply, at some point I will return the Laser Head to the new Assembly and swap the Hub, but for now since it is working fine I will forgo having to take the player apart again.
Again thanks for the info, much appreciated.

Boy, I have a Sony SCD-1 (that I bought in 1999) and I've never had to mess with the laser or any other mechanical parts at all! Still works perfectly. Unfortunately, it still takes about 45 seconds to load an SACD and it still plays only 2 channel SACD's.....

The SCD-1 uses a different laser unit.

It seems that earlier Laser Assemblies have a more robust build, made to last.
To tell you the truth, I have had problems with my original Assembly of the SCD-XA9000ES from the moment I purchased it. I lived with its little quirks of occasionally not reading the SACD layer first.
Now I have had the new Assembly in for about 5 hours and it will play anything I can throw at it.

Many of the early sacd players had difficulties with laser issues. The were players mostly with the KHM-230AAA laser and the HOP series Hitachi lasers.
However, that's all changed now as the newer players all have reliable lasers.
Well, a new laser had better be operating properly in the first 5 hours!!!! I've had replacement lasers begin to have difficulties in a relatively short time, like weeks. You just never know.
But yes, after having laser read difficulties it's nice to be able to just put the disc in the player and have it play with no worries!
