Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are connected
with the same potential as the
wrist wrap with resistance.
Keep components and tools also at this potential.
For detailed information see "Handling ESD-sensitive
components".
- A set to be repaired should always be connected to
the mains via a suitable isolating transformer.
- never replace any modules
