I have never heard or seen this problem, i would change the lamp and if it's not it at least you have a backup lamp.

What causes the picture to have a green tint


there are 3 color cathode in your TV red,green,blue cathode.The red and blue cathode might not working in your set that is why you have a green screen. Open the back cover of your TV you can immediately see the 3 cathode lamp at the back. Clean the lamp first using a clean clothe. Power up you tv and see whether the 3 lamps are lit. If lamps do not light up,check the circuit board where this lamp is connected re-solder all the components in this lamp. There is also an individual screen adjustment for the lamps it is located at the front panel and labeled RGB screen...try this first and let me know how it goes..

Failure to get a trully blank or black screen


Have never worked on a panasonic projector before I admit, but you get that effect when the 3 LCD panels inside a Sharp (and I assume all brands) LCD are misalligned. To get total black (LCD Projectors find this rather difficult due to the technology) the red , blue and green lcd pixels must be precisely allignend ( they are adjustable by technician and it's a fiddly job) I reckon the green panel is a touch out and it's peeking out between the red and blue squares.

Green screen


inside the light engine there is a red a green and a blue glass color filter.The heat from the lamp causes the color to burn off the glass.You need new filters .One is red one is blue and one is green.The lcd itself doesnt make the color,it is a black and white device.The colr comes from light shining through colored glass

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

Yellow circle


The huge yellow circle is either your blue filter is burnt out (very common in Zenith DLP) or you LCD cube is bad. I would bet it is the blue filter. Zeniths DLPs have 3 color filters one blue (a pinkish color), one green (a grayish brown)and one red (it is red). For the bulb indicator I would check and make sure your lamp is seated to the ballast correctly. Just take it out and put it back in.
