I didn't know where else to post this so... I have a 58" Samsung Series 5 550 plasma TV, PS3 for playing my HD files, and HDMI. Got it just after xmas '08. Worked fine for a couple weeks. Then I started noticing green static 'snow' appearing on the screen. At first, wiggling the HDMI cable in the TV socket would correct this for awhile, today the static was becoming very strong and no wiggling would fix it for long before it came back. So I'm thinking... oh great.. after all the horror stories I've read about support with TV companies and people having to box up their 200+lb TVs and ship them out and wait half a year, I'm going to have to go through all that. My HDMI cable was a cheap $25 one I got at Walmart. But, I know that all HDMI cables are the same. the 20 buck ones to the 200 dollar ones, tests have shown they give the same signal strength. But I tried replacing my HDMI cable first anyway. IT WAS THE FRIGGIN CABLE !!! WOW what a huge sigh of relief. I'm sure the actual CABLE itself in the $25 one is just as good as the $200 ones, but it was a little wiggly when plugged in. So I'm guessing it just wasn't seated properly into the ports in the TV. So anyway, to sum up.. if you start seeing static snow appearing on your HD TV when using HDMI, ** replace the cable first **. Even if you're using a cheap $25 cable, get another cheap one of a different brand. It might just be a loose connection between the cable plug and the HDMI port. That's what mine was! Hope this helps someone who has similar problems.
