WD52725 Lines in picture

I had the blinking light issue but have that resolved . Now when i use any input there are colored lines in the picture . Wavy with a slight tilt . You can still see the picture and the lines are faint but noticeable . Now when i use the HD tuner for the off air channels its clear . This is the only source that is clear . I downloaded the manual but thought i'd ask if anyone has seen this problem . Thanks for any input , James
