Default Clock upgrade in Pioneer PD-59 with PD2029A Legato Link DAC

Hello everyone - this is my first post after reading hundreds of helpful ones, so thank you in advance for everything!

I am trying to put a separate clock into a Pioneer PD-59 (stable platter), and am having a hard time getting the unit to see the clock.

The crystal I'm replacing goes into a pioneer legato link PD2029A DAC, and the only pinout I could find is here (from an earlier thread):

1 - S/P
2 - RZ
4 - VDA
5 - RO
6 - XRO
7 - GNDA
8 - GNDA
9 - XLO
10 - LO
11 - VDA
12 - GNDX
13 - X1
14 - X0
15 - VDX
16 - GND
17 - C (H384Fs)
18 - LZ
19 - MCK
20 - LATCH
21 - SHIFT
22 - ATT
23 - NC
25 - DATA
26 - BCK
27 - LRCK
28 - VDD

However, I taking out the crystal and caps to ground, then connecting the third-party clock to Xin as normally does not work. The Legato link doesn't connect both pins of the crystal directly to the resistor in parallel; one side of the crystal goes directly into the DAC.

Does anyone have a suggestion?

So, where have you conected the new clock?

What make is it ?
Is it the correct frequency ?

Have you conected the ground of the clock to the main ground near the dac ?

Post a couple of photos .. they always help.

If it ain't broke, break it !! Then fix it again. It's called DIY !

Also the 1 meg resistor across Xin and Xout should be removed.

I want to replace the clock in one of these but can't find a reference for the clock frequency - does anyone know what it is? And can anyone point me to a schematic or service manual? Thanks
