I recently had the same problem. You need to contact Hitachi (1-800-448-2244) and advise them of the issue. Hitachi will give you a local service contact who will look at your TV and advise you that the light engine needs replacement. Afterwards, you need to call Hitachi back and speak with a customer service Rep. They replaced the part (I was quoted $530) but I had to pay labor and service (($370). If your TV is 12-18 months you should be able to get them to cover both. Based on the service rep that fixed mine, he indicated he has replaced about 40 of these since late 2007. Mine was replaced last week and now I have a different issue, a bright blue pixel light. Now it's round 2 with the service department. I have not been impressed with Hitachi's customer service considering I spent $3200 on this TV 3 years ago. Hope this helps. Good Luck!

you most likely have a bad light engine.
