> I had comcast before but now i don't, don't use a converter box and somehow I was getting cinemax and other channels on the tv
Comcast was providing Cinemax and many other channels as part of your paid services and you will not receive these unless you are a subscriber. There is a good selection of free broadcast channels unless you live outside city areas. If you do, you will then need an external antenna and probably an amplifier to get more distant signals. Auto programming will not find the channels you were receiving from Comcast so there will be only accidental channel duplication; for example, if your former channel 10 was NBC, it may be channel 7 when receiving signal from an antenna.
There are essentially no more 'Analog' stations still broadcasting, they are now all 'Digital.' The abbreviations 'Std' refers to the aspect ratio (H/W) of the picture area and 'Hrc' and 'Irc' the available resolution or how many pixels and lines on the screen.

if going to straight cable 1)make sure not in an all digital market. you may need some type of box. 2) if can hook straight make sure if it it has an option of HRC or IRC and make sure it is HRC or (std) in some cases.

I would suggest calling your cable service provider. I just purchased the same TV and experienced the same problem/question. I have ATT Uverse and called and spoke with technical support. They said that you need a HDMI cable and the cable settings need to be set to HRC (High Resolution Compatible) or someting like that. The other 2 settings are analog modes! I had mine originally set to STD I just randomly picked this setting and had my TV conected to the cable box useing a coax cable, this is why it looked strange. I hope this helps? I will be picking up a HDMI cable on my way home from work today and will change my cable setting on my Samsung to HRC. If this does not fix the problem I will repost tomorrow, but I am sure this is the solution. Happy viewing!

Give them the model number of you television and tell them you are having problems completing the autoscan of the television. I hope this information helps you with your problem. 1.How do I set up my channels or run an autochannel search? 2.Are you using a cable/satellite box, cable connected directly to the TV, or an antenna? 3.If you are using a cable or satellite box you must use the remote that came with that box to change channels. 4.Make sure you have the correct input selected to view channels via the cable or satellite box.

I think you need to tune in new channels into the tv, explain the problem with more details.

If you have a cable box connected, it's synch circuits are bad. If your TV has a selection for HRC/ IRC make sure you know which one cable company is using .

Probably a bad video processor board

But, 1st try using a different type of Cable such as IRC, STD, or HRC different freqs and channels

Also, try using a vcr or dvd on one of the inputs to see if that works

Took off a couple of cable adapters (slip on types) then the TV worked fine.
