Kyocera DA-410CX CD Player

She was a fine unit when working, but alas she died. However, if the parts from this 410 might be able to keep other units running, perhaps the death will not be in vain.

Pictures here.

Any interest?

what was the final cause of death? Laser? Chipset? What ails it?

If I knew, I would try to fix it. The laser's alright because it detects disks just fine and the tracks, but no audio comes out. Before it died, complex passages with a lot of treble caused a digital crashing sound as though some component inside was faltering. After it died, I played around with the Sony CXD1130 chip some using my oscilloscope (I'm used to dealing with radars and the like with an oscilloscope, so I'm not too sure what I was doing and was following instructions I found on a Japanese page) and saw plain square waves instead of a PCM digital signal. So, I believe the issue lies somewhere between the chip that interprets the laser signal and controls the front panel board (display and keys) and the CXD1130. It's an electronic issue that may not be an easy fix or worth paying a technician to take care of. This player's death did short me a CD player and one I enjoyed.

Nothing you think using a DAC would cure?

It doesn't have a digital out; the 510CX did. My playing around with the CXD1130 was to check to see if I could add a coaxial digital out, but I couldn't get the chip to pass PCM.
