SNIP

I've had digital TV for several years now. I think I had a PACE box
replaced a couple of years ago. I've also had to replace a TV in that
time as it went faulty. Unfortunately there is no guarantee with
electrical components. Many will run for several years without problem,
some may not last several minutes. It really is "pot luck".


It has nothing to do with pot luck.
It has to do with good design.

Well designed piece of electronic equipment will last for years.

The UK does not have a good track record when designing electronic
equipment.

I always try to buy Japanese equipment.


It doesn't matter how well designed the equipment is (unless you build in
complete redundancy and hot switching circuits), if an individual
component fails the end result is equipment that doesn't work (or doesn't
work properly). In that sense it is pot luck. If you have a thousand
identical TV sets all built with the same components, one of those sets
will fail before the others because you cannot guarantee that all the
individual components will all fail at the same time.


These sets will certainly not be identical. A poor design will often use
some
components out of specification which can lead to component batch problems.
The component manufacturers will guarantee their components if used with in
their specifications. Most component batches will work outside of their spec
but are likely to suffer from stress and early failure.

All components in a batch will be different and the average parameter will
vary
from batch to batch.
