Hitachi is in the top tv manufactures out there and they had been offering the light engine and the customer pay the labor but they may have since discontinued that id get my recipet owners manuel model and serial OFF THE BACK OF THE SET
and call there customer relations and see if they offer any assistance with this

Yellow to green tent screen to hitachi tv 42v715


You have some reason to believe it will not?

Some history for you---several years ago Hitachi began along with others to have issues with the optical light engines.

With a mix of high heat from a lamp into the engine (it has a blue,green and red section inside---guess what? BLUE is the first place that gets the heat and is damaged----minus blue and you have red and green which equals YELLOW.

Several of their sets made about 6 years ago (research 50v500) had exact same issues and were settled in a class action lawsuit.

The issue can but does not always affect the entire screen.

The question really is: This set really worth the part and labor cost for the repair?

On that earlier model I replaced under warranty over 40 of the engines. Also Sony and others have had similar issues some of which were settled in court.

HOPE IT WORKS OUT FOR YOU.

Hitachi 50v710 Yellow spot


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.

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 !

I have a Hitachi 50v710


You have a defective light engine and here is what you need to do...we just went through this. You need to call Hitachi's customer relation department at 800-654-7013 and tell them the problems your having and that you think it's a defective light engine. They will initially act like they have no idea what you're talking about but will give you the names of some certified dealers in your area to call. Once you have a tech out from the dealer and they confirm the light engine problem (takes less than a minute) call Hitachis customer relation department back and tell them that a certified tech confirmed the problem. All of a sudden, Hitachi will say they are aware of the probelm...imagine that!

Hitachi will call the dealer and confirm this with them and they they will send the light engine directly to the dealer and Hitachi will cover the cost of the part (around $1500). All you will pay for is the install. Our install was $400...worth it to us since we paid $3600 for this TV 3+ years ago and it's been a great TV.

DO NOT let the dealer tell you that you will have to pay for the part. Hitachi knows about this problem all to well and they are replacing the part for free.. Again, you only pay the install. Please deal only with the customer relations department at the number I listed above. If you deal with their regular customer service people, they will have you chasing your tell. Hitachi customer relations will take care of you! Good Luck!

Hitachi 50V710 Yellow screen


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.
