Dirty CDs and / or dirty optics. Clean all the CDs, buy a CD Optic Disk Cleaner, which has little brushes on it. Available at Walmart.

An interesting test would be to rearrange the disks so the three that play are next to the three that don't.

I wrote to KLH and they sent me the schematics for the upper and lower boards. I asked if I could share them, and they gave me permission to post them for use here.

Have fun!

disconnect offending unit. then play see if same response occurs on the alleged normal unit using the offending cable interchange cables see if you get same result. Means it's bench repair ,internal electronics require specialist equipment to locate the offending item.

Hello
It will be very difficult to get its printed circuit board as it is. You can buy a populated board to your KLH from Ebay. Just search in with its part number.

You could check it by having the unit switched on a touching each of the pins of the device with an insulated tool. Making certain you don't short any of the pins together. You should hear a buzz on each channel. If you get nothing on the right then it could well have gone.
However that is a lot of messing about, as the device can be purchased for around £12, it could be easier just to replace it and see if that cures it. After all it is the device that does most of the work, so the chances are it's gone!

If you can post a picture of the fuse it might help in tracking one down.
However I should point out that fuses rarely blow on their own. And one blown is a sign of a serious overload, probably in the main amp or power supply section.
