SORENSEN XPF60-20SP service problem

[teatime]

Dear All,

Right now I have a defective SORENSEN XPF60-20SP.
I believe the problem at CPX400S/SP MAIN BOARD(PN:35555-5430-3C)
But I cannot find the schematic of this board.

I found some similar service blog as below:
https://www.eevblog.com/forum/repair/sorensen-xpf-60-20dp/
https://www.eevblog.com/forum/repair/tti-cpx400a-teardownrepair/

but  the CPX400S/SP MAIN BOARD(PN:35555-5430-3C) is different.
I 'm not sure if there is a board install on TP1 position,
I hope some one can find the right schematic of this board.

Thank you very much!

Thank you.
But I cannot find the schematics of XPF60-20 at this website.

This is actually a product produced by TTI, its counterpart is the CPX400.
It is not possible to access the schematics.

Thank you for your attention.
CPX series have some different model, like cpx400d and cpx400s,
the schematic also different.
I send the email to factory for the service manual, but the factory didnot reply me till today.
