I think you need a stereo jack to stereo jack cable. One end goes in the headphones port on your iMac and the other into your TV.

When I hook my MB to my TV this is what I do if I want sound too.

OK. Let's clear a few things up.

Component doesn't use audio as part of its specification. Your HDTV just happens to accept RCA audio (white and red) inputs with its component connection (as one would expect since this is a TV).

If you want to use the iMac via mini-DisplayPort. You're going to need a mini-DisplayPort to HDMI adapter and an HDMI cable.

Monoprice has a good selection for cheap. Mini Display Port to HDMI Adapter, $14.25 from www.monoprice.com.

This will get you video. Now, you need to look on your HDTV or manual and see if it supports digital audio in (toslink) or RCA stereo audio in (white and red) with a HDMI/DVI signal.

Every HDTV I've ever used does.

For example, here's my TV. I use a mini-DVI to DVI adapter and a DVI to HDMI cable with my iMac. I plug the DVI to HDMI cable into HDMI input 2. Then, I plug in my RCA stereo audio jacks where it says "DVI" in.

If you can't figure it out, just post a picture of the back of your TV and your model number.

Buy a mini diplayport to HDMI converter via the link below

Then buy a toslink to optical for your audio. Connect that front the 3.5 mm audio out put to an optical audio input on your tv.

Previous poster beat me to it, but here are the links anyway.

Something else you may need to consider is additional audio input for HDMI. I know on my TV I don't have any other audio inputs to go with my HDMI video input. A product like this (http://www2.dvigear.com/codvidiautoh.html) might be required to create a HDMI signal containing audio and video from a DVI and Digital Audio source.

Here's a link to download the manual for your TV: http://www.p4c.philips.com/files/4/42pf9630a_37/42pf9630a_37_dfu_eng.pdf

On page 35, it indicates that if you connect your computer via HDMI, you must connect the sound via the DIGITAL AUDIO IN input. However, that looks like a coaxial input, so you will need a TOSLINK to Coaxial converter, like this: http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10423&cs_id=1042302&p_id=2948&seq=1&format=2
