Practical Service Precautions

It makes sense to avoid exposure to electrical shock.

While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.

Always respect voltages.

While some may not be

dangerous in them selves, they can cause unexpected
reactions - reactions that are best avoided. Before reaching
into a powered TV set, it is best to test the high voltage
insulation. It is easy to do, and is a good service precaution.
