HDMI stopped working...

Dear Anybody who knows more than me about this, so around 6billion people...

I recetly purchased both a Toshiba 32'' plasma TV (regza i think) and Toshiba Satellite P300-1FN.
I also purchased a HDMI cable and have been watching movies from my laptop on my phat 32'' TV for a couple of months now. Lovely stuff.

After around 1 month, the HDMI port 1 stopped working. It just wouldn't pick up any signal from the computer, so i remove the cable and placed it in the HDMI port 2 on the back of the TV. Worked fine. (so i guess it's not the cable at fault) Again for about a month, now that's stopped working too...DA-DA-DA-DUUUUUUUUUUUUUUUUUUM...

Before, when i plugged it into the computer, both screens would turn black for around 3 seconds while they adjust the resolution, then the same image would appear on both. Now when i plug it in, the computer screen just 'blinks' followed shortly by the message on the relative HDMI TV channel 'no video signal', if i remember correctly.

WTF??

Cheers, Allan.
