Sharp xr-11xc only displays black & white

Look at the ballast module. It controls the lamp operation

According to pg. 45 in the owner's manual, you turn Keylock function ON by holding down the ENTER key on the projector for about 5 seconds while the projector is being turned on.

To take the Keylock off-- Hold down the ENTER key on the projector for about 5 seconds. If the projector is in standby mode, you can release the keylock by holding down ENTER and STANDBY/ON keys simultaneously for about 5 seconds.

I opened mine up hit the red reset in the front and now all good. If ur red light is blinking make sure ur lamp compartment is shut properly, if not the red light will blink and unit won't turn on.

the colorwheel may be bad. if it doesn't spin, the lamp won't strike. if the colorwheel is ok, replace the power supply/ballast. you can get one and do it yourself, or send it to a sharp service center. either way, try www.avsolutionsny.com. they're really good.

hold down the enter, menu, and down arrow buttons, then press power.

reset the lamp timer. hold down the menu, down arrow, and enter buttons, then press power.

have you reset the lamp timer yet? can't remember the procedure for that one exactly often hold power and down and left arrows whilst plugging in power. Check info on instructions that came with your new lamp.

Hi,
You can download user manual of Sharp XR-11XC from HERE for free as website will ask you any of your email address only.
User manual has all info about this unit.

You may have to reset the Bulb Life Timer. When the power is turned on, you simultaneously press the "right arrow", the "down arrow" and the "menu" buttons, then press the "standby/on" button, it should zero out the Bulb Life Timer and it should come on.

Hi traks137

You will have to reset both the lamp and filter timer before it will change the status of this unit.

Your user manual will have all the steps in it on how to do the required resetting.

Thanks for using Fixya !
