Report "I have a Mitsubishi DLP Projection TV WD-73727. After warming up within 15 minutes the reds start fading to pink and the light areas appear blotchy and washed out. As time goes by it gets to where the picture is unwatchable. Faces and skin are a pinkish purple and backgrounds have a greenish tint to them. Also get some flashing on the right side of the screen after long warm up. Had a local country TV Tech come in yesterday. He took off the back and vacuumed everything within reach. He removed the box containing the circuit board and checked all the connections, unplugged them and plugged them back in. After a $100 bill it still does the same. he thinks? it might be the power supply or the main circuit board. Both I understand are very expensive but I would like input if others have had this same type of problem before I start laying out a lot of bucks. He thought at first it was the color wheel but he thinks now that the problem is elsewhere. Thanks.......Don"
