Hi, I havea 46″ Samsung LCD TV

What’s the best thing to clean it with? Also, is there anyway to get rid of the foggy look left on some portions of the screen that you can notice when it’s turned off? Like if you had wiped it with an anti-static cleaning wipe the screen has a sort of barely noticable streak.
Also I was wondering if these foggy streaks become permenant if you wait too long to clean them?

ive tried the colored av plugs in the side ports but nothing shows up, but when i try the hdmi cable everything comes up but it responds slowly to the ps3 remote

i heard it makes the graphics look better but i already got the adapter and the 3 color wires and the graphics look great should i grab the hdmi wire or is it just the same thng

picture and we want to get the most from our t.v. Currently we have a Panasonic DVD/VCR player. What do we need to buy to be able to watch movies in High Definition. Is that what Blue Ray is? I have seen those blue ray dvd’s but I didn’t know what they were. Anyway, as you can see I am clueless about this so any info you could provide is appreciated.

All of our electronics are Sony. I wantd a Sony television but the only one I liked was the 46 LCD Sony. I don’t like projection though they do have the best picture. Our Final three options are the panasonic, Hitatchi or the Sony. The Panasonic and the Hitatchi are both 42 inch and they are also plasma…excellent picture. The Sony is larger (46 inch) and it’s an LCD and about a thousand dollars more. I’m willing to pay more cuz it’s larger and it’s sony. Other than that I don’t know whether the panasonic or the hitatchi will do…I’d appreciate any opinions
