This used to be my favourite player till volumio…
However, after 12 years in storage I decided to listen to it one more time as a reality sound check.
I connected my beloved player to the system, i inserted a cd which was red in a split second, pressed 5, and…disaster hit “private investigations” was completely covered by some kind of very powerful annoying digital noise!
I checked every single electrolytic cap and power supply and regulators and everything is within spec or better! And as if this is not enough I found another guy in youtube having exactly the same weird problem! Check this sound out at 337esd video
What is even more weird, is that I tried an external dac and although it locks excellent, the outcome is exactly the same, a lot of noise!
I have no idea what else to try, thus I really could use some help here.
Any input or idea is welcomed as my experience with cd players is limited.
thank you !

Very thing is cleaned and checked by now but the problem persists, I now tend to thing that the RF chip cxa1081 or the digital chip cxd1125 is problematic…
Most scope measurements around cxa1081 are very dirty and with low signal strength

I finally managed to easily replace the ram chip attached to the cxd1125 demodulator chip and now music is at last there. But still the problem is partially there as although now the music is clear there is a small pulse heard inside music every 4-5 seconds randomly as short noise burst. I guess I have to also change cxd1125 which is a major task with its 80pins! Let’s see…
Hi,
I'm not a technician, but I've read many times that resoldering pins of a chip can sometimes work.
Maybe it's worth trying before replacing it.

No, it does not worth replace capacitors or any other component blindy. This is a nonsense.
I hate this fixation of replacing capacitors like it would solve every electronic problem.
For to solve any electronic problem, you have to be methodic and try to find the origin of the problem.
