51'' Philips rear projection TV with color issues

I have a 51'' Philips 51PP9100D/37 that I recently bought used. The TV is supposedly less than two years old. The first thing I noticed is that the picture looks to have a yellow tint to it.
For example, white writing appears yellowish to me. I then noticed that there is a bluish white spotlight effect towards the middle of the screen which actually appears to move a bit at times. A better example of that would be when it is a black screen with white credits, all of the writing appears to have a light shining from behind creating a bright cloud around the writing.

Dark scenes are extremely dark, colors are way off, but in general the clarity is not too terrible...it's not unusable. I don't have HD hooked to it yet but it doesn't matter if I'm watching satellite or a DVD, I get the same problem.

I found info in the forums for adjusting color convergence, which I attempted with little to no results. This tv only gives two color options in the menu; red and blue. I can adjust the red just fine, but when I adjust the blue, the spotlight cloud effect is so bad behind the crosses that I can't tell if they're off or not.

Any suggestions/diagnosis?

Thank you!
