CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do
not straighten prefolds in the FFCs. You
must
ensure that all FFCs are fully seated in their connectors.
Failure to fully seat an FFC into a connector can cause a short circuit in a PCA.
Some parts are sensitive to electrostatic discharge (ESD). Always perform service work at an ESD-
protected workstation or mat. If an ESD workstation or mat is not available, ground yourself by
touching the sheet-metal chassis
before
touching an ESD-sensitive part.
1. Disconnect all the connectors.
