Question about Hitachi 50V710 50" Rear Projection HDTV-Ready Television

2 Answers

I have a hitachi 50v710 problem started with yellow spots in the center and corners of the screen now the whole screen has a yellow tint to it. have been told that it is the light engine that is the problem but the authorized service center in my area wants $300 to come out and look at it and $1200 for the light engine. I found a place on line that sells the UX25307 light engine (LC57)for $635. how do I know this the right part for this problem?

The LC47 UX23682D (DR and a few more) are replacements .. the LC57 is NOT the correct engine for the 50V710.. The Engines do vary from about $450 to over $1000.. the original is the most expensive but Hitachi seem to have produced variants to fix this very common problem. There is a class action suit in progress for another model with the same issue. It seems to stem from filters on the engine getting clogged and causing the engine to overheat. Pete

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,

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 !

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.
