    Have you seen if a service center can just replace the defective LCD panel in the set? This option would be much cheaper.

The best thing to do is to call Hitachi and see if they would be able to help with the cost of the repairs because it will be expensive.
Hope this helps,

The only way to repair this is to replace the optics engine assembly, Light engines are rather cheap these days, try looking on www.tristatemodule.com for a new or refurbished one.

Hitachi rear projection LCD with yellow blobs on screen


I have the same tv and the same problem, but my yellow is a cloud around the outside of the screen. My tv was recently moved, and a repair shop told me that sometimes in a move these tvs light engine takes a shock and causes a yellow "band" on the screen. I am hearing that these light engines are not cheap either. Hope this helps you.

55 inch hitachi lcd projection tv has yellow and purple blur near the center of the screen


This, sadly is getting to be a very common problem with all Projection LCD TV's
Colored Blotches on an LCD Projection TV are usually caused by defects or marks on filters or lenses on one of the LCD panels themselves which are all located 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 visually inspecting the lamp itself and the lens that it shines onto. The light engine is an expensive part ($600-$1200) to replace and requires major disassembly. Have a tech confirm-Get an estimate -Be sure to vote/rate me if this helped Thanks!

Picture issue


No,sad to say it is the end of your TV. Your Light engine"optic block"is bad. Caused by too mich heat.
Not cleaning the vents in the tv,smoking in the house can clog the cooling vents and internal filters.Causing poor air flow for cooling. The spots are from burnt polorised film on the LCD panels.The cost for the new light engine is about $600 + a costly core price. Encompass is down for the moment to get an exact price. But it is high. Time to get a new Flat Screen.And BUY THE WARENTY.!!! They all still have bugs in them. Costly to repair. I do the work for the warenty company for central FL. I repair 9-12 a day.One service call is more than the warenty. Light engine would have been covered. Sorry for the bad news. I have 3 of the 50" and 2 of the 42" in the shop for the same. Sony is the worst for this. Panasonic...
never a problem. Just a lamp once in a while.But the Samsung LCD/ LCD/led backlight is the best for the money.

These tvs have had optical block problems. How old is the TV? This may be under warranty.

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 !
