I relaced a bulb and then my vivitek 56" started to do wierd color flickering, turns out that there was dust in the color wheel. I fixed by taking off the back and with can of air blew lightly into the color wheel area ( has tiny hole) I didn't put the nozzle through the holes. But the minute I did that a big piece of dust came out and tv is working great. Hope it helps

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..

WHEN I TURN IT ON A BLUE SCREEN SAYS TO RESET THE LAMP HOUR METER OR REPLACE THE LAMP. IT HAS A NEW LAMP . HOW DO I RESET THE HOUR METER?


hello Plug the power cord back into a properly grounded wall outlet. Then press the POWER button on the projection display or the
remote control to turn the power on
While pressing the VOL- button on the projection display,
hold down the PIP or SPLIT button on the remote control
simultaneously for more than 5 seconds.
When the lamp time reset procedure is complete, the
above screen will appear. (This screen may be different from
the actual screen.)
Note: When the lamp time reset is complete, the LAMP
indicator goes out. i hope it helps

Sony xl-2100u lamp


Refer to your owners manual on lamp replacement. Remove the old lamp and look at it. If it looks "blown" (like a flashbulb) then it is defenitely defective.

Blue tint on half the screen


Sounds like the lamp is not far from going out.... I would get that replaced before you have no tv at all. It will go from semi blue to burned out lamp pretty quick.
