In every headphone jack schematic I have ever seen there are series
resistors that prevent any possible damage if the headphone wires are
shorted.... it is not like a low impedance speaker output that if it
is shorted you end up blowing the audio output amp.
More than likely there is a bad jack, cracked solder connections,
cracked board traces, bad jack (I repeated this on purpose)..... or of
course you could have a marginly incompatable headphone plug.... try
another set of headphones even if the first pair seems to be fine on
other equipment.
