There are no lamps in this set, you have picture tubes, if the tubes don't line up, you need new convergence chips, this is the most common failure in all rear projection tv's, you might also have burnt open resistors next to the convergence chips. if you don't have good soldering skills then you must have a repairman fix this.

I have a hitachi 50vf820 with green tint to it


Its a DLP type set that uses a lamp for a light source.

With the color turned to zero stand back and examine the image.

If mostly all green or areas are green you may have a issue with the optical light engine--either damaged inside from the heat of the lamp or the portion that processes red, green, and blue information bad.

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..

Replacing the lamp will do the job. It is the lamp that is faulty not the gun or the mirror.

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

Red tint on screen


Good Day,

Try resetting the TV by unplugging from wall outlet for 3 to5 minutes then plug back in. If no fixya take front grill off and panel and adjust the screen controls, turn color off adjust for Black & White Picture. Good Luck, big IRISH.

Red?Green picture


If you are connected to a HD cable box or sat. rcvr. using component cables, I would then suspect a loose or bad blue connection or cable. If you have Comcast and have their supplied flat component cable this is a common issue.
