I have a Philips 27' Flat Screen CRT 27RF70S television. Recently, a problem has developed. I noticed it a couple of weeks ago. There are white scanlines running across the top of my screen usually only making a big difference when the screen is white. When it is dark, they are barely visible. It was just a couple of lines at the top at the beginning, but now it is progressing down the screen. I can barley even see the top half of my screen. When I turn it on, three lines, one red, one green, and one blue go across the screen. I have know idea what is going on and just want it fixed. The TV is only two years old so I don't know why the heck this is happening.

You are having problems with the vertical blanking circuit, or the vertical output circuit.
You will need a qualified technician to have a look and see which it is, I seriously doubt the picture tube is on it's way out. Everyone thinks it is the only part that ever fails. usually it's the last part to fail.

It sounds like the CRT is on its' way out. The situation will not get any better. Your best bet is to have the TV checked and get the CRT replaced (expensive). You may want to think about upgrading to an LCD TV, since HD has become extremely popular.
In any event, have a qualified technician check out your TV - they will be able to tell you exactly what the problem is.
(FYI - I work for an electronics company that makes & refurbishes a variety of TV & other electronic equipment)
Good luck.
