RCA d52w20

I have had my RCA since 2003 and it has worked perfectly, until now. I have this grey and white static screen. I turn it on and the green light appears, however, thats it. There is a bit of color at the bottom of the static. I have no sound and the menu wont even pop up. We only use this tv to hook up to the xbox 360. I unplugged it and the same things occur. I tried changing the channel and it blinks like its changing channels but no number appears in the upper right hand corner. If anyone knows anything about this please let me know. Thank you!
