Electrostatic Sensitive Devices
All ICs and many other semi-conductors are susceptible to electrostatic discharges ESD).
Careless handling during repair can reduce lifetime drastically.
When repairing, make sure that you are 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.
