Tonight my son noticed an area of yellow to yellow-greenish discoloration on the bottom half of my Hitachi 50v710. At first is was hard for me to see, but I fear it is getting worse. My set had the lamp go out last fall, which was replaced under warranty. I will attempt to post follow-ups as I learn more.

There have been two possible diagnoses posted in reply to the
Yellow-green discoloration problem. One of them said the problem was
the Light Engine and the other said it was the Optical Block. Can someone please explain
what the difference is and how to discriminate between the two . I
really don't want to sound like too much of a dummy when I talk
to Hitachi customer service and/or Warranty representative.

Thanks,

Gdaddy

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.

My problem started with a yellowish blotch in the middle of the screen. Now the color keeps chaning so that everything is shades of green. Where can I get an Hitachi optical block myself?

the light engine is most likely the problem or it has dust ball up in it.
check the lamp for discoloration if all looks OK . that could get costly.
if you have never worked on this set you can destroy the set be careful or take it to a shop.

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.

Hitachi 50V710 has a yellowish circle in the middle of the screen

If you're good with electronics you can probably do it yourself. It's the price of the part that hurts ... around $1000.

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.
