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)

Hi ponponhead,

You indicated that it works "most" of the time. Quite frankly it should work, 100% of the time. What happens when it doesn't work, what do you do to get it to work properly?

Well, when it doesn't work, the light blue blanket falls upon the laptop monitor, and then it goes back to the way it was, HDTV remaining blank.

I went to the Apple store and changed the mini display to DVI adapter. That solved it.

A Ro, you've definitely gotten some bad advice, but consider that the Apple adapter may be defective. I would either try it with another display or else return it for a replacement.

This advice seemed to simple to work, but it did for me after trying to plug and unplug various times and ways. Thanks =) ...

Update: I changed the refresh rate to 60 Hz (via the Displays system pref) and I now get a picture. Audio fixed via the Audio pane in system preferences.

I was able to view my background only until I hit command & F1. This allows me to see whatever is on the macbook display.

Hi. How did you resolve this problem where your tv only showed the desktop (no icons)? I have the same problem. Please help.

To gordymac: How do you change the refresh rate, i thought of this myself but was unable to find these settings (im using the latest version of SL)

I use a mini plug to RCA adapter and hook that up from the headphone port on the Mac to the reciever. I don't think the sound works through the HDMI cable with macs. Hope that helps

This worked for me too.

Just check the "show displays" box and everything works all of a sudden.
