klh r5100 and schematic..?

[50nstillhifi]

I am repairing a r5100 receiver KLH.

I have isolated what appears to be the issue but want to cross-check.

I pulled up schematics but was led to a Samsung diagram for a headset?

Did I do something wrong.. and if so where can I get the r5100 diagram.
I need to take some transistor power readings.

Thanks!
