I have been told I need a new optical block to correct a yellow screen.
I was told this is a known problem with Hitachi by one of their authorized service dealers, but customer relations is stonewalling me on this. Any ideas?
I have a similar problem. Whites are a shade of yellow. My major problem is there's blue smear in the middle of the screen and two smaller ones in the upper left quadrant of the screen.
I have called Hitachi and mentioned what I have researched on the Internet. They said if I get an authorized repair service to confirm that it is the light engine, as a "good will gesture", they will for one time replace the engine, but I have to pay for the labor. One repair service I have contacted charges $92 just for a estimate service call.
I'll probably keep this for another 2 years until it craps out, then get a sound technology at the time, but nothing with a light engine. Probably plasma or direct LCD/LED.
I have a similar problem my tv developed small blue dots all over the screen then a yellow haze formed in the middle. i dont know where your located but i found a service center called Tech Knowledge in Jacksonville, FL that will drive to your house to fix it. He said it is the light engine and it is common. Hitachi said as a good will if i could supply my receipt of purchase they may would cover the part and i would have to cover the labor.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

You should be able to call Hitachi at 1800-Hitachi
and they should be able to tell you if that part number
is accurate. I am always a little leary of doing business with companies that claim to have parts and are not a Authorize Parts retailers for the manufactured part I am seeking. If they have a good return policy, they are probably ok.
I hope this helps,
I found out that Hitachi has a class action law suit against them for the light engine problem. I called them and asked what they were going to do for my tv which is out of warrenty. The reply was that they would pay for new light engine. I said what about labor. No they would not pay for labor. I asked to speak to supervisor. I was told by supervisor that the tv had to be inspected by certified repair person. Cost for this was $125 but would be applied towards the total labor cost. Repair guy came to house walked in and said he did not even have to turn tv on to know the problem. We called Hitachi to set up shipment of part. Hitachi told me at that point that they would cover all labor costs also. Part has been installed this week and tv is like brand new set.
I have recently developed the same yellow spot problem on my Sony KDF-E50A10 50" LCD television...a large yellow circular hue that takes up the bottom center of the picture and is especially noticeable against a white background. It has been diagnosed as the optical block (light engine) and without an extended warranty Sony refuses to assist with the repair cost. Repair was estimated at $1,100 plus tax and travel fees to my home. So you see, it is not only a Hitachi problem. You would think they could build something that would last more than two years considering the initial cost of over two grand for the TV !
I contacted Hitachi (800-448-2244) on 02-18-09 and spoke with customer service rep. name Joyce. I explained the yellow in the middle of the screen and told here a Tech came out and said that the problem was the light engine not the light unit. She immediately said that she would send a brand new Light Engine to the repair company that diagonsed the problem. She said I would have to pay for labor. The light engine is a $1000+ part and the repair company said labor would be $300 dollars. The key is you have to say that a tech looked at it and diagonsed it as the light engine and not the light unit. Find a repair company in your area and let the customer service rep. know that they looked at it about a month ago and you can't find the paperwork. The customer service rep will then recommend a company in your area to come and look at the TV. The tech company will probably charge a tech fee $100+ dollars, and about $300 for labor, all total $400 for parts and labor is not bad when the Light Engine itself is a $1000+ part. Hope this helps.
Light Engine and Optical Block are the same thing ... just different names. It's listed twice many times so that it's easier to search on the web. Hopefully Hitachi will do something about it some day. I plan on letting everyone out there know about it so we can all go after Hitachi. There is a Suit filed against them for the 50v500 set that has the same types of problems ... perhaps it will cover the problems with the 50v710 also. Hitachi did absolutely nothing to help me with the problem. I had to find the part and fix it myself.
