    Area in center of screen has a yellow tint. I have not tried replacing any parts but if the figure of $1200 is right I will not be buying another Zenith.

Sorry that I have to be the one to let you know this but the light engine in your set has a spot that has developed on your lens. It is not possibile to clean this without making your picture worse. The light engine would need to be replaced in your set to fix this and the cost will not be cost effective. Part number is 3141VSN916C and I cant find it at any dealer for less than 1200 dollars.

Spot in center of screen, if the color pictureis black the spot is blue, if the picture is white the spot is yellow.


Spots in screen is commonly caused by defective LCD on the optical assembly. LCD replacement is very difficult. I suggest to contact the nearest service center at your area.

Large yellow spot in center of tv screen


Sorry, but there is no cheap method of repair for this unless it is in warranty.

This TV will require replacement of the LCD Prism unit.

This Prism blocks and allows colors so that the 3 LCD images may be mixed to produce the final image you see on the screen. When this becomes damaged or defective, it leaks colors (light). This Color Leakage apears as spots on the screens.

Where you see the spots is where the specific spot on the prism that is leaking light, the specific color that is leaking also.

This parts cost alone is normally $500 to $1000 dollars but is usually replaced under warranty.

Good luck.....

Yellow Spot dead center on screen


Any color spot is never the lamp with this type of set.
the yellow spot is caused by the optic block (Engine). Very expensive to buy.
Little over $1000 plus labour with a qualified technician.
Sometimes technician may try to clean or repair inside but most likely won't succed.
good luck.

Yellow spot on Sony 55"


Possible dust in light engine? What ever you do, don't blow it out with the set on or hot. This easily equals instant death to bulb.

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 !

Yellow Spot dead center on screen


most likely the yellow dot is due to a burn in the picture on the "green" lens. It's not removable because it's burned it, but you can try cleaning it because sometimes, dots are caused by dirt. The worst that can occur is that if the dot is permanant.
