Hi all, hopefully someone can shed some light into a tv problem I have.
The
problem is that when I change channel a noise is heard comming from inside
the tv (not from speakers), this noise sounds the same as when the tv is
switched on (sounds like static charge) and it lasts for about
0.5-1.0seconds. This noise does not always occur, it also seems to make
this
noise (sometimes) during brightness changing from one scene to another.

The tv is a 3 month old Metz Artos 82 Pro, is this noise normal operation
of
the tv? Does Extremely High Tension (EHT) have anything to do with this?
The tv has V/H EHT compensation and many other settings.

Thank you.



It's normal, the HV will change slightly with image brightness, causing the
tube to charge up again when the brightness decreases.
