Hopefully someone will be able to help. I haven't seen a posting on this issue yet. I recently (2 days ago) had the color wheel replaced. Since the color wheel was replaced, I have ripples/wrinkles/waves in the picture. Sorry! I don't know how else to explain this problem. It's really strange. The picture would be great without them but it's almost unbearable to watch. Does anyone know what could be causing this problem????? I've also recently replaced the lamp and just today (trying to fix the problem) I dusted the lense. There were also some splotches which dusting the lense seemed to have corrected. It's been one thing after another with this TV recently. Any help is greatly appreciated.
