Blue area near center of screen

I have recently, within the last 6 months replaced my bulb, and in the past week have just noticed a blue cloud near the top center of my screen. I have tried to reset and it won't go away. I have just started using a HDMI cable that looks like a USB cable and have noticed it since then. Also ever since I have been using the HDMI cable there is a pop when I turn off the tv. We have direct tv and have made sure that my connections are tight. not sure what to do or try next please help. thanks!

    I have the same damn problem....just replaced my light bulb 3-4 months ago and the "blue" cloud has now recently appeared in the center of my screen. I was quoted $7-800 dollars for it to be fixed and it takes 2-3 hours to complete.

    has anyone had any luck on getting Hitachi to own up to their flaws?

    Same problem. Replaced the bulb and 3 months later the blue haze appeared. Called Hitatchi and they wanted to convince me this was not a known issue with this set. Convinced them to provide the part...which of course is on national back order. Gee if this was not a problem, how come the part is not available. When I called the servicer and told them what set I had..the first question was..have you called Hitatch yet? Before..I even told them the problem...

    Developed a blue haze down the center of the screen, larger at the top, tapering out as it went from top to bottom. This problem showed up one month after replacing the bulb. Opened up the bulb compartment thinking it was the bulb, but it was okay. Cleaned the light engine lens, and removed a coating of dust, and a smoky looking compound. By shining a light onto the light engine lens, I could see a milky looking coating on the inside portion of the lens. So far I do not know how to clean that area, and I beleive if possible it would clear up the problem. Maybe the high heat generated when the original bulb burnt out, caused this smoky film to be deposited. I am going to call Hitachi and see if they will do anything to cure this problem. 62VS69A purchased 11/2007, replaced bulb 3/2008, and now have a blue haze picture to look thru.

    Blue area showed up on left side of screen about 2 months after lamp replacement. Luckily I have a service contract with Sears. I was told projector needs replacing and my service contract will cover the $1100.00 cost.

I had the same problem with the screen turning blue after I had the bulb change. I just had to watch the tv with the blue haze, could not afford for another repair man. The bulb cost me over $400.00 to get it fix. So after about 6 months or so, the blue haze kinda faded away to a lighter yellowish tint, then you could not notice it at all, but the screen started to get darker. I just thought it was these movies made in a darker screen. But Guess what: my blub blew again.
It cure the blue tint. This time, I will order the bulb and put it in myself. If I knew about these bulb, would not had bought the tv. Other than that I like the tv. showed a good picture before all this bulb trouble. Why in the world does a bulb cost this much??????

It may not be the light engine. I also have the cloud, and since I was told that touching the bulb surface could cause problems, I took out my bulb to take a look. The fault is Inside the bulb. A cloud has formed on the inside of the bulb dead center. I have a feeling this is the problem and replacing the bulb again is going to be the solution. By the way, I buy the bulb alone and put it in the casing myself. The last time I got a replacement the casing was slightly and I do mean slightly, out of line with my set.

Uh Oh! blue screen of death. Your light engine has warped a little from overheating and is distorting the picture.

My suggestion to you is to get on the phone with hitachi and start complaining, then keep complaining until they agree to pay for it. You may have to get the problem diagnosed by a pro before they agree to pay for it though.
