I forgot about the KSS240 but I think there is no such 'solder bridge'.

Can you tell from this dodgy photo if there's a 'solder bridge' on the KSS240A?

Default kss240a

If memory serves if there is no solderbridge there is a shorting strip you have to remove from the connector before you connect your ribbon cable to your new optical block...

There's no solder bridge, and no metal strip on the ribbon cable, at least not on the basic laser unit I was trying to fit. The job is done, problems solved, once again thanks to your help here. Actually easier even than netlist suggested as the 4 screws and springs don't need to be removed, nor the wheel; just slide out the axle, disconnect the small ribbon cable and bung in the new one, takes about 5 mins.

Hi Hugo,

Excellent instructions. Especially the picture showing the bit where you push the plastic stopper aside to allow the axle to slide through, I was stuck at that point until I saw the picture. Picture does say a thousand words.

Thank you very much.



Raymond

Default KSS240A replacement

Hello Hugo and other posters.
Your instructions re the sony KSS240A were useful to me too.
My player is a Sony and it's been erratic in recognising CDs for the last few months. I hope that replacing the Laser module will cure the problem.
The Sony mechanism is pretty similar to the one pictured in your post. I've removed the KSS240A and am waiting for my new module to arrive.
I didn't have to remove the metal plate with it's rubbers and springs but had to take out the two front screws to raise the plate so that I could slide out the shaft. Here's hoping that the re-assembly goes as smoothly.
I understand from the posts here that no adjustments are needed, I hope this is so.
Thanks again for the advice and photos.
Regards, Don.

Default Arcam Alpha 7 CD player KSS-240A problem

I was wondering if you can provide me with some help? I bought a Arcam Alpha 7 CD player through eBay at the start of the year. The CD player has never functioned properly skipping uncontrollably through the tracks and was instructed to replace the laser http://www.youtube.com/watch?v=o73YgSEIv5g I purchased a replacement laser and am having great problems removing the casing that encloses the laser to replace. Any helpful hints would be very much appreciated.

Hi Cheeseplant. I printed out an illustrated instruction sheet to go with some spare KSS240A replacement laser units I had/have. If you want to PM me your postal address I can send you a copy.

Thanks for your kind offer Kora, tried to e-mail you but am under moderation so is not allowed. my e-mail is raymond.elliot@gmail.com if your able to forward electronically. Was struggling to remove the black plastic casing to enable me to change over the laser, maybe i'm missing something here, a latch or other mechanism as I don't want to force open as i'll inevitably break... cheers Cheeseplant
