Red spot Growing in the middle of my Projection LCD screen

I have had my Hitachi LCD unit for over 2years. I am beginning to notice the gradual presence of a red spot growing and becoming visible on the screen. It is more noticeable when the picture light level and content is low. When the picture has alot of color and light content the problem is not as apparent. So what is behind this gradual degradation?

Re: Red spot Growing in the middle of my Projection LCD...

We took in a 60v500a with the same problem, Customer bought a new set. We took hers apart. Here is what we found.
1 there is a squril cage blower and a small air duct that cools the lcd screens and polarizer lenses. Yes there are 3 polarizer lenses one in front of each LCD screen.

These start to overheat and discolor. Maybe the filter for the fan clogs up.

Don't really know.

You can pull the LE and vaccum the filter clean every 3-6 month.

You can remove the lenses and maybe the tv will look ok maybe not. I have read where some have had there repaired and now they see vertical lines in the screen. This seems to be a quike fix by removing the melted lens. Cool A.

Re: Red spot Growing in the middle of my Projection LCD...

You have the infamous "red cloud" as they call it and no matter what you personally do to the TV, it will not resolve the problem. The problem is you have a defective light engine and Hitachi is aware of the problem. We started noticing the red cloud in the middle of our TV (we have the 60v500) about 2 months ago and it got worse. After LOTS of online research, we were convinced it was the light engine. When we called Hitachi, they claimed to know nothing about it but THEY DO! They did give us the names of two certified Hitachi dealers in our area and when the tech came out, he could tell within one minute that we had a bad light engine.

I then called Hitachi back and told them that the tech confirmed that we had a bad light engine and all of a sudden, they knew about the problem...imagine that! They told us that they would call the dealer we used and confirm this with them. They did call the dealer and within 2 days, the dealer had a brand new light engine, sent to themby Hitachi, and they came out and installed it...TV is like brand new.

Here's the kicker...there's always a kicker. If your TV is not still under warranty (ours is 3+ years old so ours is not) Hitachi will cover the part...around $1500 but they ask you to cover the install by the dealer. Our install was $400 and they did the install in our home...they did not have to take the TV into their shop. We felt like paying $400 for a $3600 TV (price we paid when we bought it) was worth it!

One last thing, deal only with the Hitachi Customer Relations Department...NOT CUSTOMER SERVICE. Their regular customer service folks will have you chasing your to speak. The Customer Relations Number is 800-654-7013. If you're TV is not under warranty and you're willing to spring for the install, it's well worth it. Don't let any dealer tell you that you will have to buy this $1500 part. Hitachi will send it directly to them and you should only pay for the install. Good Luck!

Re: Red spot Growing in the middle of my Projection LCD...

The light engines that Hitachi is sending out are not the same as the originals. The originals had a very small circular opening for cooling that would clog up fairly easily. The new light engines have 2 rectangular openings about 5 inches long with a different filter material that does not clog as easily. They seem to have corrected the initial flaw in the design. Although the light engine that I just had installed only lasted about 3 hours until it developed a red shadowing problem. I am awaiting another light engine.

Re: Red spot Growing in the middle of my Projection LCD...

Thanks Varian!
Your Best Solution was excactly right, and the phone number to Hitachi Cust. Relations (1-800-654-7013) was terrific info. They answer within moments. I informed them of my red cloud and fading picture and that I knew from the internet that they were well aware of it. As you said. And they said to have the technician speak to them while he was here at the house. So Sear's, came out the next day and I called Hitachi and they agreed to send the part to us directly for free and Sear's credited us the diagnostic fee of $105 and then charged us $242 total for the installation. Should have the part in a few days and Sear's will come out and install it the day after it arrives. Nice experience for a bad deal, thanks to . Sear's technician also told us that the light bulb will be next and that it costs about $330 from them. But he showed us how to install ourselves. Hitachi also said they would walk us through that self installation if it happen or when it happened and they said it was cheaper through a distributor than a service dept. Probably about $189 to $239. Just good info for the future.
Thanks to the web and fixya for getting us through the ugly "red cloud".

I have a red glow in the middle of the screen and the color is dim. It has been gradually getting worse as the year has gone on. Is this a bulb issue or a convergence issue?

This is light engine issue, light engine produce image and project it front screen of TV.
I'm afraid light engine replacement would cost you much, $1000 plus, check with local tech for estimate.

Red tint covers entire screen

I think your TV set combine projection and LCD technology, if you already replaced the lamp, that would have been first suspect on other projection models, It is likely to be LCD or polarizers burning out. This is common on LCD projection technology TVs, and cause colored spots forming on the screen.

My Hitachi lcd rear projection 50v500 television



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.

My Hitachi 60VG825 projection TV is 3 years old. For the past several months the screen has been turning blue around the outer edges & this past week a large yellowish green spot the size of a...

Sounds like Calibration is needed on the projection internals. Your TV uses a rear-projection system and the problem is either in the imaging LCD Unit or the light filter. I see in a previous thread you have changed the bulb. You can invest in a voltage regulator to keep the hardware in factory condition.
Also you can burn a DVD of a stuck pixel remedy video and run it on the screen with full brightness and full contrast. This is used for plasma burns and stuck pixels on conventional Flat panel TVs but can repair color issues with projection systems. This therapy is focused on the imaging unit between the projector and the main drop of your tv.
please feel free to post a more in-depth description or any changes

Tv screen has a red/orange glow in the middle -should be black

I have the exact same problem. I had purchased a new lamp shortly after the warranty expired and never needed to use it. I decided to install it today to see if that helped with the red glow. No difference. Someone else posted that when the TV is moved (we just moved from Canada to the US) it can misalign or damage some component. Still trying to figure out what that is...probably cost more to fix that a new TV!!!

Same problem

The red death as its called.

Very common in the 50v500 and 50v700 series.

it is caused by a blocked filter deep inside the TV, nearly inaccessible.

The LCD panels overheat (red one or blue one) and the light engine needs to be replaced.

You are better off living with it unless you have a warranty.

Sorry it wasn't better news.

Hitachi 50V500 Red Spot

Unfortunately if you're not a technician Hitachi won't even consider sending you a LE for install... They will confirm your status and have you fill-out several documents.
As to the other part of the question, the service manual won't help - there is a procedure for memory re-initializing and after performing that you still have the spot then LE is called for.. But again, unless you're a tech with those letters behind your name Hitachi won't accept the results.
That said, we have done several of these and Hitachi has been exceptional to deal with pre and post install.
Hope this helps!

It is a failure in the light engine itself. You will need to have it replaced. Here is a link to that rather costly part.
