I have an iPhone and an Sharp Aquos LCD TV and no other real speakers. Is it possible, with the correct cable, to output music from my iPhone through my TV speakers? If yes, what cable do I need?
Yes - you just need to get the audio in. It may have RCA (phono) audio inputs (especially if it has component inputs - the audio are the two red and white coloured round connections). Failing that, you can buy an RCA to SCART adaptor for next to nothing.
Then you just need a minijack to RCA cable and you're done.
