On the connector X1, joystick, tape in and tape out, happens absolutly nothing.

Is it possible that X1 is defect or make I something wrong? I solder the wires like in the schematics.

Where did you connect something to X1? Sprinter has an internal cable that connected to X1 and has external connector on the back of system block.And pins are different on that 2 ends.

I bought the Sprinter 2000 as used. There was no cable. I made an cable which goes from the PCB to the outside of Sprinter.

This is from the schematics for X1 internal:

1-T_out....2-GND
3-T_in......4-J_VCC
5-JK0.......6-JK1
7-JK2.......8-JK3
9-JK4.......10-GND

I take a connector with flatcabel from the internal connector and outside I have one connector for tape out and one for tape in. The rest from the cables I use for the joystick. This is a 9 pin sub-d connector. Soldered like this:

Normal..............Sprinter 2000

1 Forward..........JK2 - Down...7
2 Back...............JK3 - Up.......8
3 Left................JK1 - Left......6
4 Right..............JK0 - Right....5
5 NC
6 Fire.................JK4 - Fire.....9
7 +5V................J_VCC.........4
8 GND................GND..........10
9 NC

As I understand Tape In/Out and Kempston Joystick will work only in ZX mode

P.S. Also you need to switch Up and Down

Up and down is still the same as forward and back.

Only working in ZX mode? How can I reach ZX mode? Starting spectrum.exe without parameters?

It depends on what version of BIOS you have - on old one it was some key to switch to ZX-menu (if I remember correctly), but on a new one you should have on floppy or hard-drive all set of files as ROM-images for all ZX-modes etc...

P.S. If you have spectrum.exe then it looks like new BIOS (3.00)
