My Sony 1031Q has developed some very faint wavy lines in the picture. The lines fade in and out and very in size and intensity (pulsate). It is only really noticeable when there is a light (not white), mostly solid color screen. The exact problem is a little hard to describe. It appears to be some type of electrical interference. I have eliminated my wiring and AV equipment by hooking a DVD player directly to my Iscan Pro (which is located just above my PJ). The PJ does not seem to have any other problems and looks GREAT! Any ideas on what to check would be appreciated.
