Removal and replacement strategy
WARNING!Turn the product off, wait 5 seconds, and then remove the power cord before
attempting to service the product. If this warning is not followed, severe injury can result, in addition to
damage to the product. The power must be on for certain functional checks during problem solving.
However, the power supply should be disconnected during parts removal.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.
CAUTION:Many repair operations will require you to flatten or straighten flex cables. However,
where possible, try to avoid doing so. You must make sure 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.
NOTE:To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread
pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping screw-hole
becomes stripped, repair the screw-hole or replace the affected assembly.
Throughout this chapter, the reinstallation process should follow the reverse order of the removal
process documented. Where necessary, the tasks include reinstallation tips to aid in the installation of
replacement parts.
Electrostatic discharge
CAUTION: Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD
reminder when removing product parts. 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.
Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the product.
