When I hit the source button, nothing appears. It is hooked to cable, we can change channels and hear sound, but no picture. HELP

Just bought a new samsung led-lcd 46” 1080p tv and want to know if anyone knows the best way to set up the picture to make it look spectacular. Thanks.

When I ordered a 46″ Samsung LCD TV, series 7 TV (LN46A750) from electrozone the salesman offered an upgraded model (LN46A750R1FXZA) which is suppose to include DCDi technology? Has anyone ever heard of such a thing? Or did I get screwed by agreeing to pay extra for this?
Here’s an updated after I spoke with a manager at electrozone manger:

The DCDi upgrade is a replacement/enhanced card for the HDMI slot on the back of the TV. So if your like me, and only plan to use HDMI for DVD’s (as I have std coaxial cable) this upgrade is not for you. Thankfully I was able to get this upgrade cancelled before the TV shipped.

Also, this upgrade does not change the TV model. The model number change on my electrozone order was only their internal way to know whether to ship the base model or the upgrade model.

I purchased a nintendo wii for my child for christmas. It came with the RED YELLOW AND WHITE cables for video and audio in the box. I cant seem to hook it up without it coming in black and white. why is this? the sound works perfectly and everything. just the picture is in black and white. please help!

We just bought this tv in March. My husband and I were watching a movie and all of a sudden the tv turned off and keeps making a clicking noise like it’s trying to turn back on. We powered it down and turned it back on but it just makes the clicking noise. I really don’t want them to fix the tv I’d rather have a new one. Any ideas what’s wrong with it?

Looking for the best price on a 46″ LCD samsung, its easy to search by this number, “LN-S4692D”, the best price ive found so far is 1827.27 free shipping from Buy.com. Let me know if you see any better. Thanks

There on sale for black friday at walmart

Hey, going to buy one of these two Tv’s this weekend, having a real hard time deciding though. What are your opinions on them and which one do you think is better, price difference not an issue. Will mainly be used for gaming, movies then tv.

Thanks in advance
