Background:
I have a portable TV which I want to add a headphone socket to.

Plan:
Open TV.
Find wires (probably just 2, I doubt it a 14", £80 TV has stereo)
Add chassis mounted switch to the live (?) wire.
Add chassis mounted headphone socket to the casing
Wire the socket to the other 'side' of the switch

This will (I hope) leave me with a TV which I can switch between
headphone and speaker modes.

thoughts anyone?

Hi Michael,

Buy one of these : http://tinyurl.com/mcgf then drill a hole through the
plastic casing to suit the size of socket, in an area that will not
interfere with any of the innards. Find the speaker wires and trim them
down or add to them until you have enough wire to reach the new socket. The
black wire will be connected to the outer part of the socket (the socket
casing) and the red wire will be connected through the two lugs on the end
of the socket. When you insert the 3.5 mm Jack Plug, the action of pushing
the plug in will separate the connection of the red wire from the main
circuit board and the existing speaker and will make the connection to the
headphone jack plug only.

This is really a simple enough job but as others have said in their replies
" PLEASE BE CAREFUL OF THE HIGH VOLTAGES INSIDE THE TV "
and be careful not to touch any of the capacitors on the PCB or you'll get a
shock that will badly burn on both the entry and exit points of your body.

Good luck with it.
