Hitachi hdtv 60" yellow circle on screen

The screen has a big yellow circle on it.  It started out as a small yellow circle in the middle then spread out to the larger screen.  Hitachi told me I need a new lamp but other people told me it's not the lamp, it's the light engine. Before I spend $ on a new lamp, has anyone  had the same problem?  thanks.  tico@aloha.net

    my Hitachi 60V715 has the same problem. New bulb does the same thing. Internet research I did favors a bad light engine. Over a $1000 fix.

    I had the "red bloom" problem that many people have reported online, so in April 2008 I had the light engine replaced. Everything was fine until now, in November 2008, when I am seeing a slightly yellow circle on the screen. It's invisible except in darker scenes. I don't know if it is going to get progressively worse or not. I guess the solution would be to replace the light engine yet again, but I don't have confidence that a new engine would be any less flaky than the two I've already gone through.

SOURCE: Hitachi Rear Projection LCD TV Lamp

Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy. Some models are real bulb hogs though. Look them up on the net (include the word complaint or repair) before you buy, or you might be sorry. Many class action lawsuits out there - even against some of the name brand makers.

SOURCE: Light Engine Problem with my Hitachi 50v500 - Solution

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 have a Hitachi 50V710 with a yellow-greenish spot in the center of the screen. It appeared there about a year ago. I have been putting off getting it repaired because money has been pretty tight. And they told me that my warranty has expired. They also said that it would cost over a thousand dollars to fix the problem. I purchased the 50" TV 09/09/04 for a total of $3336.88 what a rip-off. Now the whole screen has a green tint and the yellow-greenish circle in the center looks brighter. I wonder if it is even worth getting it fixed? What will go wrong with it next? Its a Lemon.
I really regret not buying the 52" sharp that was setting next the piece of **** that got suckered into buying. I know I learned one thing out of this,
" I WILL NEVER BUY HITACHI BRAND PRODUCTS AGAIN! "

SOURCE: Blue spots on a hitachi 50vg825

You will need a new optic block assembley. This has been a common problem found in all brands of LCD projection type television sets.

Cause for this is fine dust and particles gets "cooked" onto special lenses and even on individual lcd panels. I haven't found a way to clean each optic peices back to original. I usually find the colored filters in most of them had changed to a brownish, hence blocking that color from getting through, leaving a pink, or bluish spot like hue, or even in some cases a starfeild like patern.

Only thing can be done is to search the Internet for a new or refurbished optic block assembly to your make and model.

In the shop I work for, I've seen literally hundreds of these sets, all brand who makes LCD projections, develop this kind of problem. I've exchanged optic blocks on everyone I've gotten since 2001 - 2002 and so far never seen one comming back with same problem twice.

If you are good with following instructions, then it maybe cheaper for you to purchase a service manual with all the parts blow up, access to "Service Man Mode" with all adjustment codes, then purchasing a new or rebuilt optic block assembly... (Some manufacturers will send you a different optic block assembly of wich you must enter the Service Man Mode (SSM), for making proper adjustments per advice from their techs).

Changing one can be a real chore, so it maybe in your favor to higher a competent tech who can do the job right at a good price. If you can't find a personal tech, then shop will be next in line, however it maybe a little expensive.

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

Yellow ring on screen of KDF-E50A10 Sony Wega


The optical engine has a build up of dust. This can cause yellow shapes and blotches to appear. It is no easy task on this model to dismantle and clean the engine.

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!!!

Blue dots on LCD screen


You will most likely need to replace the panel. You will have to contact Sony and they will send a Factory Trained Technician to your home to replace it. Since you are not on Factory Warranty this repair will cost you. You may find it cheaper just to replace the television.

The tv screen is 60% blue . . . . . .


Me too! Is this a related light engine problem that people are experiencing with the "red cloud" in the middle of the screen? I just replaced the lamp, which I thought was the problem, but nope, the blue is still there. So definitely not the lamp. I don't know what to do?
