Hey, 2 months ago I got my HDMI cable, I tried to connect it to the TV but I had no signal in the HDMI channel, I could connect it through the VGA cable in the PC channel but I get no sound of course.
2 weeks ago I tried to give it another shot and it worked, I just connected the HDMI cable to the TV and turned the computer on. It worked for 3 days until I put the computer to sleep mode. Now I can't connect it with the HDMI cable anymore (I can still use VGA).
The cable is working on my monitor.
My computer:
Windows 7 Ultimate N 64-Bit
Asus P8Z68-V LE
Intel Core i7-2600K
8GB RAM
Asus GTX 580
The TV: Panasonic TH-L32C20M
My question: Are there steps to do it? Or am I missing something?

HDMI is sometimes a pain. try using pressing the windows key +p to cycle through the display modes and see if it comes up. as near as I can tell going in and out of sleep or turning the computer on before the TV etc etc can.make it forget the other display is there. so you may need to reactive it in the driver(extend orvduplicste desktop) or via the above method

Yea, it's a real pain. I tried using you Win+P thing put still nothing, it still say "HDMI" on the top left side if the TV. It worked 2 weeks before so the cable and the TV are working.
Any other Suggestions?
