IC Identification 
Several different types of IC are used in the DA100 (50Hz) chassis.  These are listed in the table below.  Note 
that although these IC’s may be available from other sources, it is strongly recommended to obtain these 
directly from Sharp Electronics (UK) Limited, or their approved distributors, using the part numbers given below.  
There can be compatibility issues when incorrect IC’s are fitted - even if they have the correct type number.
