a lot of times its green when you use component for a dvd player is caused by 2 things. first and most common reason...is that the dvd player is (keep in mind that its just a machine) too stupid to know that you're using component cables to hook things up. samsung ones do that all the time. it gives you the green screen so you can change the output without plugging in another set of cables. go into setup menu on the dvd player (or there might be a switch on the back) and tell it to output a picture through component. if that doesnt work, the component cable (the red cable) is busted...but that rarely happens.
no idea about the cable card. it sounds like the tv is in the antenna mode. make sure the coax is plugged into the right port on the back(there should be 2 different ones on the lg's) and make sure the tv settings are right.
Has anybody encountered a problem with their Plasma TV displaying too much green?
Just today I noticed that when I am using the Component Video to play DVD, the picture is green. Seems like watching Incredible Hulk from start to end of the movie. I will test the HDMI and see if this is the same problem
I also have problem with the Cable Card. It's not descrambling the card correctly. When I want to channel 308, it displays 30-8 on screen. I have to go to channel 78-5 if I wanted channel 308. Seems like the tuner is out of whack.
I have an LG 50PX5D.
