Our old TV, a samsung, was transported from yorkshire to the north
East, and when we came to use it there was a distinct high pitched
squeal. Rather than risk something blowing I just switched it off and
used a reserve tv, but some months later I was thinking of having it
repaired, brought it out, hooked it up and switched, to be greeted by
the squeal... at which point I gave the machine a sharp slap on the
side and ping, the noise stopped! I assume something had worked loose
during transport?

No you'd given the mouse a heart attack!

But, having said that - tapping and or hitting things is a

Percussive maintenance rules!

I have always assumed that 90% of all electronic faults are actually
electrical faults, and 90% of all electrical faults are actually
mechanical faults.

So, overall, 81% of all electronic faults are actually mechanical
faults? Well, I won't disagree with that hypothesis, I believe that
approximates pretty close to the underlying causes of electronic
failures myself.

However, most computer problems tend to be software related but it's as
well to make the obvious hardware tests before being led up the garden
path in search of the impossible dream, a software fix to a hardware
problem.

When I get my customers to deliver their ailing system boxes to my
workbench, the "Six Inch Drop Test" is redundent since the act of
transportation usually acts as an equivilent substitute. :-)

If a customer's PC fails to demonstrate the reported fault when set up
on my workbench, it's obvious that anything and everything that remotely
involves some sort of connector needs a good looking at before
proceeding any further.

Even when the fault remains unaffected by the stresses of
transportation to my workbench, I'll still check the 'connectors' if
there's the slightest hint to suggest the possibility of any such
mechanical problems being the root cause of failure.

With experience, it becomes common sense to do such checks to eliminate
"The Usual Suspects" in the matter of detecting the true culprit for the
problem.
