All lCs and many semiconductors are
susceptible to electronic discharges (ESD).
Careless handling during repair can reduce life
drastically.

When repairing, make sure that you care
connected to the same potential as the mass of
the set via a wrist wrap with resistance. Keep
components and tools also at this potential.
