ICs and many other semi-conductors are susceptible to electrostatic discharges
(ESD). Careless handling during repair can reduce life drastically.
When repairing, make sure that you are connected with the same potential as the mass of the set via a wrist wrap with resistance.Keep components and tools also at this potential.
