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)

What worked for me is to reset the NVRAM.

Did you try both HDMI channels? Cause there's usually 2 HDMI ports plug it in and then try the other input if it says no signal.

Here is a video I posted to YouTube of what the 1080i output looks like on both machines.

I bought a cheapy on ebay and I went to system prefernce, hardware, display, mirror display. Solved the problem Hope this helps

THE WAY TO DO IT IS JUST PULLING YOUR WEB BROWSER OFF THE SCREEN TO THE RIGHT UNTIL YOU START SEEING IT ON THE TV!! HOPE THIS WORKS FOR ALL 🙂

Also, using gfxcardstatus and switching to integrated only (Intel HD Graphics 3000) the MBP does the blue screen ONLY when I unplug the cable/switch to another HDMI source but NOT when I plug it in.

I have fixed the problem by returning the Mini display port to the shop and got a new one. They also suprised since they did not have the same problem before. Now, everything works like a charm!

For display go to SYSTEM PREFERENCES, DISPLAYS, ARRANGEMENT, and CHECK BOX MIRROR DISPLAYS.

For sound go to SYSTEM PREFERENCES, SOUND, OUTPUT, and CLICK ON YOUR TV'S NAME
