That is either a faulty light engine or a bad optical system. On this model the repair is expensive.as the parts are respectively $600 and $980.

I believe that this model has no color wheel, because it uses led dlp technology as many new Hitachi, otherwise it would have been an easy repair.

    I wanted to add that if you contact Hitachi customer service , locate service centre , and talk with a technician, you will probably get similar response, eventually they may add video controller board as eventuality, but from description I do not think that is the problem.

    Here global contact page , call tehm and locate a service center: Contact Us : Hitachi Global.

    Here also my previous comment :

Splochy green spots on screen


Colored Blotches on an LCD Projection TV are usually caused by defects or marks on filters or lenses in the light engine (or optical block) First confirm that the lamp or main lens is not discolored by removing the lamp (unplug set and let cool before removing!) and inspecting the lamp itself and the lens that it shine onto. The light engine is an expensive part ($600-$1200) to replace and requires major disassembly.

Yellow spots


I have been told by a local repair person that Hitachi might replace the light engine at no cost because it is such a big issue... has anyone hear about this... I am going to contact them directly also.

Dark yellow halo on screen


I believe you have a optical Engine causing the problem. Due to the cost, I would call Hitachi to see if they could help with repairs.
Hope this helps,

Yellow spot


Good Day, dv28;
No, the lamp will not correct this. The TV has a bad light engine, it's very common for this TV and very expensive. Call the manufacture and try to get a concession for the part. They normally give it about 75% of the time.
Good Luck, big IRISH.

Yellow spot in center of screen


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 !
