i have a 2007 white macbook and i've been trying to get the right cables to connect it to my tv. i recently purchased a mini dvi to hdmi (female) and then a hdmi (male) to rgb. i can't seem to get it to work :mad: any help would be greatly appreciated.
 
Since I don't know of any Mini DVI to HDMI adapters, I might be not the best help.
Have you looked at Monoprice.com yet for such cables?

And as there are too many Magnavox models for me to check all their specs, I guess all of them have HDMI inputs.
Why not use that input instead of the HDMI to Component adapter cable, which you linked to here. Strangely enough they mention audio on that article too, but that would not work, as Mini DVI does not support audio transmissions and the colours on that adapter (Red, Green and Blue - RGB) don't match audio RCA cables (red and white/black).
Anyway, that HDMI to Component adapter cable will probably not work since those Maganavox TVs have no Component input (again, too many models for me to check them all, thus I only looked at one).

Maybe have a good look at that guide I linked to and at the manual your TV came with, if the Mini DVI to HDMI adapter and a HDMI cable and the HDMI input of your unknown TV does not work.
 
I have a similar problem. Have a Mini DVI to HDMI adapter as well as the HDMI cable but no sound on TV. Video image good.

Early 2011 MBP 13", i7, Mac OS X Lion 10.7.4 (11E53) and LG HDTV.

If i link a iPad to the same TV, no problem. Video and sound.

What am I missing?

Since your Mac has a Thunderbolt port, thus it needs a Mini DisplayPort* to HDMI adapter, your MDP* to HDMI adapter (I assume you confused Mini DVI** with Mini DisplayPort*) might not have the correct specifications to transport audio too, maybe check again on the page or specifications you got with the that adapter.
Have you also made sure to check check System Preferences > Sound > Output or OPTION/Alt click the sound/volume icon in the Menu Bar, to see what is listed and checked as Output Device?

Mini DisplayPort (MDP) / Thunderbolt
Mini DisplayPort is the current digital standard on all current Macs to transfer video to an external display or TV. It has been introduced in 10/2008 with the release of the Unibody MacBook and MacBook Pros and has gradually been adopted on all other Macs.
MDP is capable of transmitting video, and since 2010, audio too. MDP is a miniaturised version of DisplayPort. It is also license free and can support resolutions of up to 2560 x 1600, which Mini DVI and Micro DVI are not able to do.
Since 2011, all Macs come with a Thunderbolt port, which is meant for fast data transfer and also as means to connect to an external display device to mirror or extend the Mac's screen.

Mini DVI
Mini DVI is a digital common interface on the later G4 12" PowerBook, on Intel iMacs till 2009 and on the white and black pre-Unibody MacBooks and on Intel Mac minis before they changed the design to Unibody.
