I have a 54" Samsung PCN5425R with some problems right now, the picture is a little blurry and blue doesn't seem to be showing or something, stuff thats supposed to be blue is more of a greenish color. I have an HTPC I am building which I connected to it to load one of those pictures with the color bars and blue looks black. Also, there are like moving horizontal lines, don't really know how to explain what they look like but they are across the picture.
I was wondering if there was a service mode on this I could safely use to try and fix it on there. The TV is out of warranty and I'm not sure its worth trying to get it repaired somewhere. It is about 5 years old.
Here is a picture I took of it:

And here I found a thread on another forum abou the same TV with one of the same problems:
