I have a 4 year old Sony DLP widescreen and recently developed thin lines across the screen fron side to side. They are slightly bowed and are about 2 inches apart. Very noticable when the screen is dark. Any Ideas?

Sony never did DLP... Being four years odds are it is LCD RP... gotta model #?

K.... how about a CRT RP 
Sounds like you are describing retrace lines typically related to setup of the CRT cutoff, G2. You will need to call service.
