Yellow to green tent screen to hitachi tv 42v715


You have some reason to believe it will not?

Some history for you---several years ago Hitachi began along with others to have issues with the optical light engines.

With a mix of high heat from a lamp into the engine (it has a blue,green and red section inside---guess what? BLUE is the first place that gets the heat and is damaged----minus blue and you have red and green which equals YELLOW.

Several of their sets made about 6 years ago (research 50v500) had exact same issues and were settled in a class action lawsuit.

The issue can but does not always affect the entire screen.

The question really is: This set really worth the part and labor cost for the repair?

On that earlier model I replaced under warranty over 40 of the engines. Also Sony and others have had similar issues some of which were settled in court.

HOPE IT WORKS OUT FOR YOU.

I have a projection Hitachi 57F500A the color is very yellow, I lived with it until the screen starting having the same image as the one I see in the covergence repair kit ad. I think I have two problems....


Its very unlikely that you have a bad tube in this model..that would be very rare...it may just be the convergence or possibly the fluid in the lenses has clouded up. Both are common issues. Read this and see if it helps http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

My 1997 ultravision projectionn tv is having yellow shadows.


Best case scenario is your lamp is failing and will need replacing ($200 - $300). Worst case scenario is the panel is starting to fail, meaning it would not be worth repairing. The set is 14 years old and has probably reached its end of life. You can probably replace it for less than a thousand and not only have HDTV but a digital receiver as well.

Hello,
If you have RED color that starts from Center of the Screen,(no red color on sides ) 100 % your light engine is deffective..
In order to solve this issue Replace Light Engine Control Board (also called Driver Board ) attached to light engine.

Color issues with Hitachi 60V715


You likely have a problem with your Optical Engine. It is very expensive to replace and should fix the problem. The lamp cannot cause color issues. You may have dust/dirt contamination in the engine and it could be clean by a servicer or technical person. The blue LCD panel or polarizer may have failed in the engine giving you blue and yellow (lack of blue) type symptoms.

I have a hitachi projection tv that has yellow areas on the screen. tv repair guy says it is the engine. does this make sense? in checking tv repair on line it seems to me to be the projection lamp. does...


When tv has a blue or red or yellow circle in middle of screen and it is very faint looking in most cases it is the light engine.
The cost is 650,00 plus labor. In some cases it could be the color wheel. but rear .
The lamp is not the problem

Yellow spot in center of screen


I have recently developed the same yellow spot problem on my Sony KDF-E50A10  50" LCD television...a large yellow circular hue that takes up the bottom center of the picture and is especially noticeable against a white background.  It has been diagnosed as the optical block (light engine) and without an extended warranty Sony refuses to assist with the repair cost.  Repair was estimated at $1,100 plus tax and travel fees to my home.  So you see, it is not only a Hitachi problem.  You would think they could build something that would last more than two years considering the initial cost of over two grand for the TV !

Image has yellow tint even with nothing connected


I am not a 100% sure, but that would be my first thought on what the problem is. I would call Hitachi support and go through troubleshooting with them to find out the cost of the repair.
