Error 0x20003 on self calibration dso5102P

xray52

Hello!the trigger does not work on the DSO5102P. I do the following: I connect the probe to the oscilloscope generator and press the AUTOSET button — the relay clicks inside the device a few times but the picture does not stabilize on the screen.
During the self-calibration (Self Self-Calibration), an error 0x20003 appears.
I am a good technician: is it possible to solve the problem by myself? Below data of my DSO5102P

Please input a signal and see whether a signal at Tp403.

Thanks for the suggestion. I'll be running the test next week as soon as I get back from the Christmas holidays. Many thanks for the help
