SERVICE MANUAL
EXM 400
SMT Disclaimer
Due to the complex nature of the use of SMT installed components
in Yorkville equipment, we highly caution all service technicians in
attempting to repair or replace SMT factory installed components.
Many of these components may be glued prior to initial soldering.
Replacing SMT components requires expensive
specialized de-soldering equipment and training.
Yorkville Sound will repair and replace defective SMT components
to ensure proper quality assurance and installation is maintained.
