Question about RCA D52W19 52" Rear Projection Television
Thin white wavy lines running from left to right no more than five at a time on the screen. 52" HDTV model D52W15
Those lines are called retrace lines. They are there all the time on projection TVs but you should be able to see them. When you do see them, that's an indication that the kine screen settings are too high or the supply voltage to the kine driver circuit is low or missing. There is a small, black control unit located behind the speaker grill assy in the front of the TV that has 2 sets of 3 controls. A red, blue, and green focus and screen controls. See if you can make the lines dissappear by turning the screen controls counterclockwise. If you can't you'll need to have service come out to troubleshoot it.
