nec projector lamp
Thursday, June 24th, 2010Nec Projector lamp
Projector Screen turned back and white.?
I have had an HD color projector (NEC LT265) for about 3 years and it suddenly turned to black and white in color.
Is this a problem with the lamp bulb(even though there is 30% life in the bulb left)
Or is it a problem with the projector itself, because i don’t want to get a new bulb and have the same problem.?
or is it something else?
?????????
1st, check to see that your picture is black and white from more than one source. Try your cable/sat box and your Dvd Player. If one gives you color, the trouble is with the other(or its wiring), and not your projector.
2nd, if picture is b&w on all sources, check the projector’s menu. Navigate to the video controls and make sure your “color” setting didn’t accidentally get set to zero.
3rd, if you are using Component Video to your projector, check to make sure your red and blue cables are connected. Green only will give you black and white.
4th, if none of the above worked, you have an internal problem with the projector. Color information (chromanance) and brightness information (luminance) are processed separately inside the unit and something has gone wrong in the chromanance circuitry. You will need the help of a professional.
Hope this helps!
Edit:
Sorry, a lamp cannot cause this symptom.
