Looking for Answers about samsung HL67A750A1F?

IS MY TV 3-D READY, AND WHAT DOES IT TAKE TO HAVE IT AVAILABLE FOR PROGRAMING? ALSO, ARE THERE CURRENT UPDATES AVAILABLE FOR DOWNLOAD TO THIS T.V., AND HOW DO I UPDATE THE UNIT....THANKS

When we purchased this HDTV we noticed that the viewing screen, when turned off, had marks on the screen when a light was positioned a particular way. If you look straight forward you do not see these marks. After reading the instruction manual, we learned that a soft cloth was the way to clean the screen. We tried to remove the marks which look like scattered finger marks going every which way but the marks remain. After our research, we think this is a manufacturing defect or maybe in shipping the screen bounced towards the box and this produced these marks.

We love this HDTV but this is very disturbing to me and would appreciate an answer to where these marks came from.

Turned on tv and lights come on around power button but no picture or sound- what has happend?

I checked the FAQ and many of the questions were not answered.

I have the HL67A750 TV and The Samsung BD-C6900 blu ray player and would like to set them up. I also would like to know what glasses I need

TRYING to use 3D with TriDef software. Hdmi cable pluged in to Hdmi3/DVI and DVI out on video

we were watching tv last night and it went black, no menu no oter input sources work, three blinking light on the front of the tv

How can I fix this or do I need a repairman.

Turned on the tv and all pictures have a green tint. Tried adjusting the color and only green and red appear. It looks like the blue LED is gone. I've read online that it can be easily replaced ( I have extensive electronic experience). Are the parts and documentation still available? Any help would be appreciated. We love the TV. This is the first problem we've had with it.

Is there a bulb I need to replace?
