Greetings,
I have a small project that I need help with. I have a new LCD TV that has NO outputs of any kind, no RCA outs, no headphone jacks - nothing. I need to build a headphone connector into this TV (it's for a senior who lives in a care facility, she can not have the speakers on but can use the TV with the wireless headphones if she could connect them to the TV). Ideally I would like to have the jack automatically switching off the speakers when the headphones are plugged in, but a separate switch coulld also work. Now here's the problem: the speakers inside a TV do not seem to be connected to a common ground wire. The headphones jack is the three-wire connector where one wire is shared (ground) between the two channels. The speakers inside TV are 8Ω, 5W small speakers. I would greatly appreciate guidance on how to make this work and what parts are needed.
Many thanks in advance.
P.S.: No I cannot use another TV - this one is unique because it plays movies from a USB key and is 25" in size. Any other model that can play from USB is 40" and larger and that's too big for where it is going to live.
