Mini display port to HDMI problem

I have my aluminum Macbook perfectly wired up to my 32 inch RCA HDTV. Nothing will come up on the screen, I've tried detect display, I've tried restarting the computer, unplugging and plugging back in then detect display, turned the tv of and on, but nothing is working. I am currently running Snow Leopard, but when I was on Leopard this process of attaching the TV to the computer just took about 10 minutes of doing desultory processes that I've already described. Any suggestions on how to make it work the first time?

Early 2009 Aluminum Macbook, Mac OS X (10.6.1)

I have a late 2011 MBP and I already have sunflowerbed. Is there anything else I need to do to turn on the audio?

Hi Ya'll, my hdmi connection was working perfectly up until a few days ago. My MBP will not turn flash blue or do the handshake at all. It does not detect a connection whatsoever. Any thoughts???

that was precisely my problem, read my post on page 46 for what fixed it for me.

My hunch is that it is indeed a logic board issue if you have tried all solutions discussed in this thread

If it WAS a logic board - how come it's such a universal problem, with so many machines... and intermittent...?

and, if it is, then replacing it will be the answer - so go for it, eh?

When you have your TV hooked up an icon of a TV appears in the toolbar at the top of the desktop. Click on that and you can change the setting to mirror your computer.

DJXXL thanks. Your suggestion worked as you described. Now if only I could connect to LCD projector through MDP to VGA. Cheers

Try a different adaptor, try a cable instead of using an adaptor. You may have to try a few methods before finding one that works.

I was so frustrated until I read dmjgkart's post. I could not watched purchased HD content from iTunes on my 47" Vizio television until I followed these steps. Now it works perfectly.

I had same problems--

Fixed it by turning on mirroring(Displays--arrangement) & then detect displays & then choose 720i

Did you "detect the display"?
