A person can be in contact with 230 volts and have no consequences. It is only when the person makes contact between the voltage source and a grounded metallic conductor (neutral wire) that is a return source back to the supply, that a person needs to be concerned about. This also applies to grounded metallic structures which can carry a fault current back to the grounded distribution panel. All electricians make a practice of turning the power off before working on any electrical equipment.

That depends on what the suply is if your power suply is 230 then you run it on 230.
It would probably not work on 150 volts. Many televisions can be adjusted to work on 230 v (Europe) or 120 v (USA).
The classification of 230 volts is in the low voltage range.
