Introduction and Safety Information
This service manual provides essential information for the maintenance of Grundig color television receivers. It is crucial to observe all recommendations and safety instructions outlined in the 'Safety' Service Manual (Part Number 72010-800.00) and any country-specific regulations.
For the television receivers specified on the front page, refer to the Service Manual CUC 2030 F / CUC 2031 F. This manual details the differences and additional modules fitted to these TV receivers. A list of individual modules and their relevant part numbers can be found in the tables on page 4.
Basic instructions for servicing are provided in the following documents:
- Service Manual CUC 2030 F / CUC 2031 F (Part No. 72010 020 8000)
- 2nd Supplement CUC 2080 F (Part No. 72010 020 8200)
- Safety Instructions (Part No. 72010 800 0000)
Due to the conversion of the EDP system, previous 10-digit part numbers have changed to 12-digit numbers. For example, a previous part number like 29504-111.22 is now 29504 111 2200. During this transition period, both forms may appear in the Service Manual.
Spare Parts Lists
The four-figure designation in the spare parts refers to the last four figures of the part numbers of the chassis or modules. For example: 3100 ⇨ 29704 004 3100.
