Luxman D-225 optical pick-up replacement

chicco_36 · 20th November 2005, 12:31 AM

I have one non-working Luxman D225 CD Player, which have dead laser. Can anyone help me with info about optical pick-up type on this model? Schematic will be even better.
Thanks,
Chicco

Anyone have info of this Luxman CDP, or i'm the only one with this player?
All the best,
Chicco

Hi Chico,
The part number on the laser head is SOH-AP. Make sure the cable is good (or be careful when changing the head).

Why do you think the head is bad? It's the most common misdiagnoses.

Hi Chris,
I'm not shure at all, but everiting seems to work ok, logic, motors, sensor switches...
This is Samsung head i gess, not fammiliar with it.
I didn't have schematic, so it's hard to examine everiting and to be 100% shure.
I will apriciate every help,
thanks to all!

Hi Chicco,
What is it doing exactly? Do you have an oscilloscope?

Hi Chris,
When the disc is in, spindle motor rotates the disc and laser tries to read it without success for a couple of minutes. With empty tray there is red light from the laser head, and if disk is not inserted, “no disk” command on display shows up. So, I guess logic is ok, but laser is too weak to read the disc content properly.
Chicco
P.S.: I can borrow from a friend an old Philips 10 Mhz oscilloscope if is worth at all.

Borrow the Philips, much better than nothing.

I will look into the archives and get back to you tomorrow.
