It could be that the "White Uniformity" needs to be adjusted which would probably require an authorized service technican to perform. Otherwise, the problem may lay within the light engine itself, also requiring a tech.

Tonight my son noticed an area of yellow to yellow-greenish discoloration on the bottom half of my Hitachi 50v710. At first is was hard for me to see, but I fear it is getting worse. My set had the lamp go out last fall, which was replaced under warranty. I will attempt to post follow-ups as I learn more.

P.S.-
There have been two possible diagnoses posted in reply to the Yellow-green discoloration problem. One of them said the problem was the Light Engine and the other said it was the Optical Block. Can someone please explain what the difference is and how to discriminate between the two . I really don't want to sound like too much of a dummy when I talk to Hitachi customer service and/or Warranty representative.
MY HITACHI IS YELLOWISH GREEN ALL THE TIME. DO i NEED A NEW LAMP?
