First---There is a class action lawsuit(google the model number and you will find about this).

Both the 50V500 AND 60V500 HAD THIS PROBLEM.

The red oval in the middle of the screen is a burnt light engine--called the optical engine. The lamp this set uses shines into one end of the engine which has a series of lens etc and the picture comes out of the 3 inch lens on top of the engine and is directed into a mirror which reflects it onto the screen.

The heat from the lamp causes slight separation of one of the lens inside the unit.

HITACHI knows about this problem and was for a while providing replacement engines for 200 dollars;
Now the least expensive replacements I have seen are over 600 dollars wholesale---the new engines are
supposed to not have the same kind of problem.

Considering the cost of the part and major labor to replace it(you have to dismantle the entire set) it is most likely not worth repairing. If you are an original owner you may want to look into the class action law suit.

Sorry for the bad news but I have replaced several of the engines in this set.

If you have questions or need advice let me know here.

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.

Color shadowing on screen


I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.

Hitachi model 60v500a.the middle of the screen is a little yello


If you Google "60v500a light engine" you will learn a few things about this set which was first sold in 2003.

There are some class action lawsuits out there for several Hitachi models made at about the same time.

Most of the time these sets develop a discolored area fairly large in the middle of the screen---a lot of them had a large red or pink oval area but other colors are possible.

This set uses a LAMP for the light source and it directs the light into the optical light engine--at the top of the engine is a 3 inch lens that the picture comes out of and is directed into the mirror which puts it on the screen.

Lots of these sets develop a "burn" inside the engine from the heat--there are a series of lens and baffles inside---even slight separation inside will change the color in some area of the picture.

I am sorry to give you bad news but I have replaced a lot of these engines under extended and when they were new mfg. warranty.

The part is no longer available from Hitachi new--the only way to get one is to remove the one in the set and have it sent out for "rebuild" and the last time I saw one the engine was over 600 dollars at the wholesale level not counting the fact that it is major labor to replace.

Find someone in your area familiar with Hitachi and this model and you will see what I am talking about.

Even though this is not good news, I think it is what your problem is.

Red circle in middle of screen color is way off


You have a problem with the light engine. Hitachi has extended the warranty on some of these. This is a major expense with major labor charges. Better get in contact with a local Hitachi authorized repair facility.

Have a green tint over 90% ot the center of the screen


I had the same problem with my 60V500A about a year ago. The screen got a red tint in the center and the image was fuzzy in that area. A new lamp didn't solve the problem. I did some checking and found out that the original light engine used in this model had a cooling issue that could cause the light engine to overheat and distort the LCD panels. My warranty had run out more than a year before this happened so I figured I was screwed since the light engine was so expensive. I decided to call Hitachi tech support and see if I could get a discount on the cost of a new light engine since the cooling problem was a known issue for this model TV. I calmly explained to them that I was aware of the cooling issue in the light engine and that I felt like a $4000 TV should last more than two or three years. Tech support gave me the phone number for my local authorized Hitachi service center and I gave them a call. Once the technician confirmed that it was the light engine that was the problem Hitachi sent him a replacement light engine at no cost to me. I was WAY past my warranty period so I still had to pay for the labor to replace the light engine. $300 for labor was a lot cheaper than buying a new light engine or tossing the TV and buying a new one. I have to say that Hitachi earned my respect for admitting there was a problem and doing what was needed to correct the problem more than a year after my warranty had expired.

Hitachi 51f510 Color problem


for testing, place the green crt board on the red crt and see if the red crt lights up and the green does not. If the green does not light up then check for 200+ volts on the collector or the output transistor. if you have that kind of voltage thee then check for an open resistor. If not then make sure the transistor is not shorted

Good Day, christenand;
It is a repair that will cost from $350.00 to $ 600.00 depending on service company. It's not real easy but not hard for a trained tech. I would suspect that the problem lies in the Convergence circuit. If you call for service make sure you use an Authorized Service Center. Good Luck, big IRISH.
