Hitachi 50V500 blue blotch problem, defective light engine

I have a Hitachi 50V500, that I bought December 03. We had problems with a red shadow next to the outline. I just accepted that problem, but now 5 1/2 years later we have a bright blue center and blue blotches at the center bottom of the screen. We have been very careful with the TV and not used it that much at all.
I called H customer relations today and was told that they now have an address where you have to send your "out of warranty claim", and you need to enclose copy of purchase, a techician's diagnos, and a prior repair history, because (I could not believe this fabricated requirement) they "don't help you out with your first repair". I asked them if they are aware of the class action lawsuit, and the lady answered that the lawsuit is the reason why they cannot help customers anylonger, but need to follow this procedure. BS.
I contacted the Dallas attorney and they said that they "don't handle the Hitachi claim anylonger, and didn't want to say why. I asked if they maybe had "settled" it with H, she still just repeated first answer.
I will look into another class action lawsuit. Any hints?

SOURCE: Hitachi 50V500 Red Spot

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

My Hitachi lcd rear projection 50v500 television


THIS IS A VERY COMMON PROBLEM IN BOTH THE 50V500 AND 60V500---IT IS A BAD OPTICAL LIGHT ENGINE---MAJOR PART---WHOLESALES FOR OVER 600 DOLLARS!

IF YOU HAVE AN EXTENDED WARRANTY---GET IT IN FOR REPAIR!

There are already several class action lawsuits in several states concerning this problem in this model.

What happens is the lamp the set uses damages lens etc inside the light engine--the engines are now being sold on an exchange basis and are all rebuilt units---that are supposed to not have the same kind of problem as the early ones.

If this helps you, rate this solution as I do this here for FREE.

Hitachi 50v715 light engine problem


Lots of their sets had this problem(sony also has the same problem and they now cover the engine for 3 years) I have learned after being in this business for over 30 years---people who take no for an answer do not get anything---keep going up the chain of command and keep of record of who you talk to with date, name, etc If you spend enough time on the phone you may get somewhere--you have nothing to lose by trying. If you paid for the set by check or credit card you should be able to prove you paid for it and when.

Blue half moon shadow on top of screen


We had this same problem with our 60+ inch Hitachi. Except our tv had a red hue in the center of the tv before we replaced the bulb and then the blue hue joined the red one after the replacement. It ended up that our light engine was defective (which is an extremely common problem in Hitachi tvs). You should read through some of the forums on here to see if you can find your solution exactly (that is how I figured out my problem was our light engine). You might have the light engine problem also, but I am not sure since you don't have a red hue. Hitachi pays for the replacement light engine part (worth $1200). I just finished the process and now my tv is like new. If you want me to go more in-depth with the light engine repair process let me know.

Hitachi 50" Ultravision too much yellow, not much blue


First of all sorry for delay.
can you provide a image of yello shadow.I believe it seems to be technically say "ghost image"
If it is ghost image we can try by entering SERVICE Menu and adjust RGB level of the light engine.

Good luck

Hitachi 50v500 blueing problem


I am not expert but before you go to a lot of trouble, read all of the post on the infamous "red cloud", "red blob" and "blue streaking". In evey case, it appeared that the light engine was the problem. We just had our light engine replaced and the TV looks perfect. We dealt only with Hitachis Customer Relations Department 800-654-7013. You will have to have a certified tech come out and diagnos the problem. Hitachi will then call and verify, with the dealer, that the problem is a defective light engine and will send out a brand new one.

We were told the part cost around $1500 (Hitachi covers that) however, they will ask you to pay for the install. Our install cost $400. Worth is to us as we paid $3600 for this set 3+ years ago and we have loved this TV. When you first call Hitchi, they will act like they've never heard of this problem but they will give you names of certified techs in your area. Once the tech confirms that it's the light engine, Hitachi will own up to the problem and send out the part.

You really should only deal with Customer Relations ( I listed their 800 number above as you will be chasing your tail so to speak with their regular customer service department. Good Luck!

Hitachi 50V500 TV: has a red line that outlines faces or text


It's a light engine defective part. Hitachi knows about it and if you call their customer relations department, they will refer you to a dealer in your area to come and diagnos the problem. Once Hitachi can verify that's the problem, they will ship the part to the dealer. We had our part in 2 days and had it installed today. No more problems. TV looks brand new. We had to pay the installation of $400 but the part runs around $1500 and Hitachi covered it. We felt like $400 was worth the $3600 we bad 3+ year ago when we bought it. The color will only get worse if the light engine is not replaced. Good Luck! It was an easy fix!
