You start by doing a Gooogle search for the error code, being sure to mention the exact error, the make and model number of the system.
maybe
"technics model pg1 error"
If that doesn't get you any useful results, post a question in English, rather than "yoof speak" on a forum like this, being sure to mention the exact model number of the system.
