If you have to get a new light engine, and that sounds like the problem, Hitach will cover the part. We recently went through this and here's what you need to do. Call Hitachis customer REALTIONS department at 800-654-7013 and tell them about the problem. When you tell them that you think you have a bad light engine, they will initially act like they've not heard about this but they have. They will however give you the names of some certified dealers in your area. Once you have the dealer come out and the tech confirms that it's the light engine, call Hitachi back at the number I listed above and tell them that the tech confirmed that it's a defective light engine. They will call the dealer directly and they will send a brand new light engine to the dealer and Hitachi will pay for the part (aroun $1500).

If you're not under warranty, you will have to pay for the install. Our install was $400 but other on this post have paid as little as $200...worth it on an expensive TV. If you're still under warranty, Hitahci will pay for the part and the install.

Once our light engine was replaced, our set looks brand new and the TV is 4 years old. Good Luck:)

Make sure your blue component cable is connected...this is the most common cause for complete loss of blue. If this does not fix it you are looking at having to get a new light engine for this tv. Sorry. Make sure it is not your source first...dvd..cable..etc

Yellow raster on tv is cause by what?


Hello
Check the Blue video output transistor for loose solder. This transistor can be located at its video output card, usually pluged on to the neck of the picture tube. There is no blue output is now, only Red and green are there. The mixing of Red and Blue color, and absensce of blue color, causes the raster to appear as yellow. The fault is purlely with blue output transistor at the video output state of your tV. If there is no loose solder, just replace this transistor with same number. If loose solderings are found, resolder that points by applying a little more solder, without making any solder bridge short in between adjecent solder terminals.

I have HP Deskjet D2466 Printer and when i want to print with color cartridge, the black color would be printed as blue color... My black cartridge was exhausted so i only can printed with color...


when the color cartridge has to make black, it uses all three colors. printing blue indicates that the color cart. is getting low on red and yellow. get a new black cart. and a new color, 'cause it' s coming due.

Let me know

TOshiba 36A41 CRTTV has a color problem, i can not see the color Blue.


If it got like that gradually suspect a low emission condition on the Blue gun inside the picture tube, this condition can sometimes be fixed by running a gun cleaning procedure, this is done with a crt analyser device at a repair shop. The other cause for a no blue picture could be a Blue color output that has stopped working, the loss of blue is suddendly when the color out fails, it could also be a problem in the signalprocesing circuit. I suggest having it checked by a tech because it would be something you could not check, first because of lack of equippment and second, you would need some technical troubleshooting skills to do the job.

Screen got yellowish color


Sounds like overstressed video cable, at least that wire for BLUE signal, 'cause when image is yellow - the BLUE color is missing.
Open the monitor and ring coaxial wire in blue insulation.

The color on the screen is green when I watch movies. How do I fix this problem?


Good day sir, your inquiry about the green lcd screen can be caused by several things. 1. The monitor/tv produces 3 colors, red green and blue, the tv mixes these three colors to produce the picture. a loss of red and blue produces this green screen. so check the cable, specially the red and blue jack of the component inputs, and the red and blue cable. 2. there may be loose contact on the signal cable. try using the video input instead of the component input. 3. the dvd player may have the problem, check the player component out jack. a loose jack port can cause these problem. hope this may help. thanks

Samsung 61' DLP Color problem.


If you are using Component inputs, check to make sure that the Blue Video Cable has not backed out of its connecting jack at either end or the cable it's self being bad. If you are using HDMI I would suspect that the Digital Board being bad. It would be odd for the Color Wheel to cause the problem but cannot eliminate it as a cause. The Lamp would cause the picture to be darker but not cause a color to drop out.
I would call a professional to trouble shoot it unless you have the knowledge and the tools to do so.
Hope this helps,
