Question about Hitachi 50V500 50 in. HD-Ready LCD Television
I'm on my second light engine, what is it that goes wrong with them?
can I send it out to get rebuilt myself?
I had whole redish/pinkish screen on my 50v500 starting a few days ago, then I read through each of the threads on this site for the samilar problems on my model. I found TVtechmaniac's solution (pasted below) solved my problem. Thank you TVtechmaniac!
Enter the I2C Service Menu, be sure the power is OFF.
1. On the front control panel, press and hold the INPUT button.
2. Then press the POWER button for two seconds.
3. You may keep the INPUT button depressed until you see the OSD with the Service Menu displayed.
4. If you don't see the service menu, please repeat Process making sure you wait until the Power blinking LED stops.
5. Execute the Memory Initialize operation after the adjustment values have been written on a sheet of paper. Highlight “MEMORY INTI”, arrow to the right and hold the button to the right (approx 5 sec.) until a check mark appears in the box. This activates the Memory Initialization.
6. After the Memory initialize operation has finished (10~15 sec, the channel will revert to CH 3.) the pink image symptom should be fixed.
7. Write back the adjustment values from your notes to their respective adjustment parameters in the adjustment mode. (In other words, set the Data Values back to the the Data values written down before the Memory Initialization procedure). NOTE: Make sure the SELECT Button is pressed on remote after every change to the values. Failure to do so will result in the data values not being changed.
8. Exit I2C menu. Press exit repeatedly until you go back to the normal picture.
9. Turn the set off-on and Confirm the picture remains in a good condition.
BE SURE TO COPY DOWN DATA SETTINGS BEFORE INITIALIZING I2C SETTINGS

I purchased my tv about 4 years ago and had to replace the engine light twice. Now i have a blue spot in the middle of the screen here we go for a third time. Hitachi is the worst brand of tv and i don't reccomend for anyone to buy one. Both time I paid a sears tech $800 for repairs. I didnt know that hitachi would send you a light engine as long as you pay for the install.

Don't pay Sears anything, Call Hitachi. They are replacing these light engines and covering the part (around $1500) if you're out of warranty, you have to pay the install. Our install was $400. I don't know when you got your light engines but up until recently, Hitachi was replacing bad light engines with refurbished ones...they're now sending out new ones. Hitachi is aware of this problem and it's frustrating that they don't recall this part. The certified tech that came out and replaced ours 3 weeks ago, said that Hitachi has recently made big improvements in the new light engines and they are replacing the bad ones with the new ones they're putting in the newer model sets. We bought this set, first generation. Not that it should matter at all, when you pay $3600 for a TV like we did, it should last longer, but other TV's are having problems (ie Mitsibushi fan getting hot and cutting off) so it looks like they are constantly trying to correct these problems.
Please deal only with Hitachi customer relations (not customer service). Their direct number is 800-654-7013. They know about this problem but will pay dumb until you have a certified tech come out and confirm the problem. Once you call Hitachi back and tell them that a light engine defect has been confirmed, they will send out the part (at Hitachi's expense) and the tech will come out and install it.
Again, I'm not an expert only going by what we've recently been through and from what we've heard about the recent changes to the part itself. It sounded like from out tech that Hitachi has just recently started sending out these "new and imporved" light engines. Who really knows...but they will cover the part. DO NOT PAY SEARS for it. They are just trying to make money one something that Hitachi is sending out for free and they know it. Only pay for the install if your not under warranty. Good Luck:)

Steeldrago he had mentioned that the glass cost about 3 dollars each? I want to know where you can get replacement parts for the Light Engine as I have had mine apart and it is just a very small fragile piece of colored glass that has a burn spot in it...There has got to be an aftermarket repair for this since Hitachi has screwed so many people. NEVER OWN ANOTHER HITACHI

The heatsink on the lcd drive board is stamped steel, the red, green and blue drive chips are mounted to the heatsink with thermal tape and barely make contact with the heatsink.
I dissasembled my light engine and the blue drive chip is dark brown from heat, you can see that only 1/8 of the chip ever touched the heat sink, also the other two chips barely make contact.
This is a manufacture defect , its just poorly made and bound to fail.
If you want to discuss this, search for "stans atm site" my email's at the bottom of the page.
I would like to get ahold of a few defective units to confirm this.
Have a great day !

We have a red blog on ours and I called Hitachi and I talked to 4 people before i got any help at all. Everytime one person told me they couldn't help i asked to talk to the supervisor, they didn't like it but they'd pass me to another person. By the time I got to the 4th person I was getting pretty upset. At first he told me there was nothing that they could do then i told him I knew a lot of people that had the same problem he said he wasn't aware of it, then I asked him if he was aware of a law suit. He told me yes but he can't discuss someone elses law suit with me. i told him I understand since i work for an attorney. I argued some more with him and he finally told me he was going to put me on hold. When he came back to the phone he told me if i can get a rep to call them to tell them the ligjt engine is bad they will mail them one to replace it and I will have to pay for installation. I called Sears and a lady called me back today and told me they were going to send a rep out. I asked her if he will call first and she asked what the problem was when I told her she said they have had a lot of calls on Hitachi tv's and when I told her what about the red blog she told me she will go ahead and call Hitachi to tell them to mail them one. She went ahead to tell me the cost of installation is $250, that showed told me they have fixed a lot more just like mine.
If anyone is having problems with Hitachi keep on to them and don't stop until they tell you they will send the part. Let them know you are seriously upset and know about the law suit. Hope this helps.

My problems with this Hitachi 50V500 model just seem to get worse. I also have the red spot but it was tolerable but now the TV keeps turning off and back on again every few seconds. I am really torn about whether to just junk this thing and buy a new (non Hitachi) TV or pay the price of repair. Considering it is 5 years old, needs the light engine replaced like everyone else and it probably is due for a new bulb, I am on the fence about having it all serviced at once and wondering what everyone else thinks. Since I paid about $3600 for it the first day it went on display in the store, I am pretty angry and will join the class action lawsuit either way. Any opinion is welcome.

Just called Hitachi, and told them we had problems with blue and yellow splotches all over the TV. They said if it is anything other than the lamp, they would pay for the part. We have to pay for the service guy to come and look at the TV, which is $50.00 and it would cost $150.00 to install the light engine, which they are pretty sure that is the problem.. Hitachi said they would pay for any part other than the lamp. If it is the lamp, the tv would start to go darker and darker which it isn't. The service guy will call the serial # into Hitachi and they will send out the part.

The light from the lamp is driven through 3 or 4 magnifying glasses, over time this magnified light will eat away at the coating on one or more of the glass assemblies right outside of the LCD assembly inside of the light engine, I'm still looking for instruction on aligning the assembly once it has been removed but the actual glass cost about $3 each. The labor for the alignment is more costly. Unfortuniatly most tech wont take the time to open the light engine. And the alignment information is held tight by qualified repair facilities. The tech who comes to your house will only be able to replace the entire assembly

My husbands uncle has one of these TVs and I think it's about 5 years old now. He rarely even uses it; only during college football season, maybe once a week. This is the 3rd problem he's had to have a tech come out and work on the thing and now finds out he's going to have to pay over $1200. to fix the light engine.
He called Hitachi and got the same BS everyone else is getting. They won't send him the part and he's already had a tech tell him that was the problem.
Funny how they will replace one here and there.
I'm gathering info for him to get into the lawsuit.

I think there is ground for a class action lawsuit against Hitachi. Do we have a Lawyer, who wants to pursue it?

After making a few phone calls to Hitachi, there replacing the light engine for me. You have to have had the TV looked at by a technican for the dianostics.. My TV was 16 mnths old bought at sears,model 50v720 with blue streak in the scrreen.
