    i purchase my tv 5 years ago and hitachi said in order for me to get my light engine replaced i would need the bill of sale,

    who keeps the receipt for that long what do i do now?

  • panda0225 Apr 15, 2008

    fyi, i called the hitachi customer relations phone number from the other postings, not the customer service number and they were very helpful and never asked for a receipt. but they did call the tech who came out to verify the problem. the number i called is 800-654-7013.

    I had this blue blob appear on my 50V500 one month ago. It started along the right edge and over several weeks got progressively larger. I read the owners manual that suggested color changes means the lamp needs replacement. Called Sears and ordered lamp ($250). Replaced lamp which did nothing, blue blob still appeared.

    I found the posts on internet suggesting the light engine was bad with Hitachi providing the part outside of the one year waranty, so I called Hitachi customer relations who told me to call back after technician inspected to verify the light engine was bad. I gave the customer relations agent the model number and the age of my TV. She said that they would need a serial number to verify the correct part.

    I called Sears who said a technician could come out in 3 1/2 weeks. This was too long to wait so I called a local Hitachi authorized service technician. He determined that the light engine was indeed bad. This Hitachi service technician called back the Hitachi customer relations agent, who refused to send the remanufactured light engine due too the TV being old (I bought the TV new less than 4.5 yrs. ago ).

    After the technician called me to tell the bad news, I called Hitachi customer service agent who confirmed that there computer record now logs me as a out of waranty on the light engine replacement. I asked to talk to the agents supervisor.

    This supervisor said that the TV was too old, 3yrs past the waranty expiration, and my TV had not had any prior service problems reported. When I questioned what what time frame was the cutoff time for providing the light engine replacement part. His reply was there wasnt a time limit instead it is replaced on a case by case basis. We went back and forth in a loop conversation for 10 minutes. This supervisor would not give me a person or mailing address to send a complaint or to send a request on the limitation of extended light engine parts replacement. I asked how I could send a letter to request a written explanation. His reply was that he told me the explanation...that the waranty had expired.

    May have lost this battle...on to the war!!

    I don't know what changed in the last week or so. My service guy received a refurbished light engine within the last week or so. Just waiting for him to come out and install it. All I had to provide was a serial number and have a tech verify the problem which I said was a red cloud on my screen. I also have to send this one back so I would assume they are going to rebuild it so they must have them available. Sorry i can't be of more help.

    I have had the same experience with the blooming red gun

    on the Hitachi light engine. The set (50v500A) is well out of warrantee

    but using the 800 654 7013 number I arranged to have a part shipped

    to the closest Hitachi service outlet at n/c save for the shipping

    and the labor to put it in. They were very helpful and did not

    resist sending the new light engine which says to me that

    they recognize they have a problem. Greg Seattle

I'm glad it all worked out with Hitachi. As far as replacing the light engine yourself, I just know that when the tech came out and replaced ours, he literally took our set apart. It took him 2 plus hours and he had the entire contents of the set laid out all over the floor. It appeared to be very labor intensive. I've also read some posts on this board where a couple of people have tried changing it out themselves only to have other problems that they ended up having to have a tech come out and fix...along with replacing the light engine. So, I would be apprehensive to do it myself. Having said that, if you do service work, as you've mentioned, and you have someone that knows what they're doing, it may be worth a shot. All I can really go on is the extensive work that the certified tech did when he came out and replaced ours. At one point, I wasn't sure if our TV would ever work properly again due to his taking the set apart but it works great and the new light engine did the trick...Good Luck!

    That's really disappointing that Hitachi has decided to stop replacing the light engine. There are dozens of us on this message board that had our part replaced for free. I guess with all of the parts they've had to replace, they've implemented a policy to not replace parts after a certain time frame which is ridiculous! I have posted over 100 solutions on this topic and I guess now I will no longer do that.



    I'm sorry for those that it didn't work out for. Regardless of the fact that they replaced our light engine, Hitachi will not get a dime of my money ever again!

DIY light engine


You have a defective light engine and you do not have to be under warranty for Hitachi to replace this part. We just went through this and here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them that you have a defective light engine. They will act like they've never heard of this problem but they have. They will give you the names of some certified dealers in your area to call. Once a tech comes out and confirms that it's the light engine, call Hitachi back and they will send a brand new light engine to the dealer and Hitachi will cover the cost of the part (cost $1500).

Here is the deal, if you're under warranty, Hitachi will cover the part and the install. If you're not under warranty, all you pay is the install. Our install cost $400. Others on this site have paid $200. Do not let anyone tell you that you have to pay for the light engine part...you do not. Hitachi has not recalled this part but they are replacing it for free. Also, deal only with Hitachi customer realations number that I listed. Good Luck

I recently had the same problem. You need to contact Hitachi (1-800-448-2244) and advise them of the issue. Hitachi will give you a local service contact who will look at your TV and advise you that the light engine needs replacement. Afterwards, you need to call Hitachi back and speak with a customer service Rep. They replaced the part (I was quoted $530) but I had to pay labor and service (($370). If your TV is 12-18 months you should be able to get them to cover both. Based on the service rep that fixed mine, he indicated he has replaced about 40 of these since late 2007. Mine was replaced last week and now I have a different issue, a bright blue pixel light. Now it's round 2 with the service department. I have not been impressed with Hitachi's customer service considering I spent $3200 on this TV 3 years ago. Hope this helps. Good Luck!

Jeanette,

If you have a red cloud in the middle of your set when the tv is black, we call that the "infamous red cloud". In general terms, you have a defective light engine. Nothing you personally do to the set will correct the problem. We just went through this a couple of months ago and here's what you need to do. Call Hitachi's Customer Relations Department at 800-654-7013 and tell them that you have a bad light engine. Initially, Hitachi will act like they've never heard of this problem before...but they have...many times. They will give you the names of some certified dealers in your area to call. Once the tech comes out and confirms the problem, call the customer relations department back and all of a sudden they will have heard of the problem. The will call the dealer you used to confirm that it's a bad light engine and Hitachi will send a brand new light engine (cost around $1500) to the dealer and Hitachi will pay for the part.
The dealer will call you when they receive it and come out to install.

Now here's the kicker, if you're set is not still under warranty, you will have to pay the install. Our install ws $400 but others on this post have been around $200, so it would be fair to say that an average install should cost $200 - $500.

Also here are some things to watch for, please do not let any dealer tell you that you have to pay for this expensive part. Hitachi has not recalled this part but they are replacing it...once you have the set looked at by a certified dealer and you DO NOT have to be under warranty for Hitachi to replace the part. If you're not under warranty, you just pay the install. If you are under warranty, Hitachi will pay for the part and install. Last, please deal only with the Hitachi customer relations department and not customer service. The 800# I listed is directly to customer relations. The Hitachi regular customer service will not be of any help and will deny this problem even exist.
Good Luck:)

You have the infamous "red cloud" as we call it and nothing you personally do will fix it. Here's what you need to do...we just went thgrough this about a month ago. Call Hitachi's customer RELATIONS department (not customer service) at 800-654-7013. Tell them what the TV is doing and that you believe you have a defective light engine. Now, they will initially act like they have not heard of this problem but they have. The will however give you the names of some certified dealers in your area to call. Once you have a tech out to confirm that you have a bad light engine (this will take the tech less than a minute once you turn the set on) call Hitachi's customer relations department back and tell them you have a bad light engine. All of a sudden, they will acknowlege the probelm exist and will Hitachi will call the dealer direct to confirm that's the problem.

Once they confirm the problem with the dealer you used directly, they will send out a brand new light engine and Hitachi will cover the cost.

Here's the kicker. If your TV is not still under warranty, ours was not, Hitachi will cover the part (cost around $1500) but you will have to pay for the install. Our install cost $400 but worth it to us on a $3600 TV that has been great up until the light engine issue. If you're still under warranty, Hitachi will cover the part and the install. DO NOT let any store or dealer tell you that you will have to pay for this part. Hitachi is replacing it with brand new light engines for free...you just pay the install.

Please deal only with the Hitachi customer RELATIONS department at the number I've listed above. That is the direct number to Hitachi's customer relations department. Hitachi customer service will not help you at all!

Once our light engine was replaced, and the tech replaced it in our home and did not have to take the TV to the shop, our TV is like brand new again! Good Luck:)

You have a defective light engine and here's what you need to do...we just went through this. You need to call Hitachi's customer relations department at 800-654-7013. DO NOT call regular customer service. When you first call them, tell them what your set is doing and that you have a bad light engine. They will initially act like they have no idea what you're talking about but they will give you some names and numbers to some local Hitachi dealers. Call one of the dealers to come out and once the problem has been confirmed, call Hitachis customer relations department back. All of a sudden they will have heard of the problem and they will call the dealer to confirm it.

Once they confirm it with the dealer, they will send the part directly to the dealer and the dealer will call you to set up a date/time to come out and install it. Hitachi got our new light engine to the dealer in 2 days.

Now, Hitachi will cover the cost of the light engine (around $1500) regardless if you're still under warranty or not. You will have to pay for the install. Our install was $400. DO NOT let any dealer tell you that you have to pay for the part once they get it from Hitachi...most reputable dealers will not try to do that. Hitachi will cover the cost of the part, all you pay is for the install.

Please deal only with Hitachi customer relations. Their regular customer service department will have you chasing your tail. Once our light engine was replaced, the TV is like brand new. Good Luck!

Hitachi light engine


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

You have a defective light engine. We just went through this and here's what you need to do...there is hope. Call Hitachi's customer realtions department at 800-654-7013 and tell them what the set is doing and that you have a defective light engine. Now, they will initially act like they've never heard of this but they have. They will however give you the names of some certified dealers in your area to call. Once you call the dealer and a tech comes out and confirms that you have a bad light engine, takes less than 1 minute, call Hitachi's customer realtions department back at the number I listed above.

Once you call and tell Hitachi that you had a tech out, all of a sudden, they will acknowlege the problem and they will call the dealer you used to confirm it. Once they've confirmed that it is a bad light engine, Hitachi will send a BRAND NEW light engine directly to the dealer and the dealer will call you to come out and install. HITACHI WILL COVER THIS PART regardless if you're still under warranty or not.

Here's the kicker, if your not under warranty, Hitachi will cover the part, but you will have to pay for the install. Our install was $400 but worth is to us on a $3600 TV we've only had 3+ years.

DO NOT let any dealer or store tell you that you will have to pay for this part. Hitachi will cover the cost of the part (around $1500). Hitachi has not recalled this part (they should) but they are replacing it FOR FREE.

You have a defective light engine and you DO NOT have to be under warranty to have it replaced. Here's what you need to do...we just went through this. You need to call Hitachi's Customer Relations Department (not regular customer service). The customer relations # for Hitachi is 800-654-7013. Tell them what's happening with your set and that you think it's a bad light engine. When you call them, they will initially act like they have not heard of this problem but will give you some names of some certified Hitachi dealers in your area.

Call one of the dealers and they will send a tech out to diagnois the problem. Once the tech tells you that you have a defective light engine (all they have to do is look at the set when you have it turned on) call Hitachi customer relations back and tell them you had a tech out to confirm the problem. They will then act like they know exactly what you're talking about...imagine that! They will call the dealer that came out and once they confirm this with them, they will send a new light engine to the dealer. The dealer will then call you and arrange a time to come out and install it.

This part is paid for by Hitachi, regardless if you're under warranty or not. If your under warranty, the service should be covered if not, the part will be covered by Hitachi and all you pay is for the install. Our install was $400. DO NOT let any dealer get the part and tell you that you have to pay the $1500 for it. Hitachi knows about this problem and they are paying for the part. All you pay is for the install. Again, deal only with customer relations at the number listed above and only deal with a dealer Hitachi refers you to. Good Luck!
