A friend of mine called me to pass by his place to check
on his DVD player which he suspected was hit by high voltage.
I passed by his place and the DVD was brought to me, I opened
it and my first stop was the power supply since power surge usually affect the
power supply especially the primary side.
The good thing with power surge problems are usually
catastrophic and therefore in most cases you can easily identify the problem
without using expensive test equipment and therefore your eyes are good enough
to locate the faulty component(s).
