Hi, Replacing the lamp in a Sharp LCD projector requires the lamp indicator to be reset. When the lamp needs to be replaced, the indicator becomes red. Resetting the counter for the lamp hours to zero will also reset the indicator to green.

Attach the power cord to the projector and plug it into an electrical outlet.

Step 2Locate the buttons on the top of the projector and simultaneously hold down the "Enter", "Menu" and "down arrow" buttons, then press the "Standby/On" button.

Step 3Continue holding all four buttons depressed until the lamp indicator light begins flashing green.The counter is now reset. Zero hours will now be displayed on the screen.

that model has a history of bad ballasts. you'll need to replace it.

you need to reset the lamp timer

The NEC’s work on a reducing time basis, they count the hours that they have been operational and refer to this as the life of the bulb – 1600 hours. When the 1600 hours has been reached the projector shuts itself down into standby mode never to be restarted even after changing the bulb / filters. This is because the unit needs to be reset, which needs to be done as follows (not included in any of the bulb replacement instructions):-

• Plug Projector in so it is in standby mode – Orange light lit, Red status light lit (not flashing)
• Using the remote control, hold down the power off button for 30-45 seconds
• This will reset the status button, removing the red light
• Power up the projector and select Menu
• Select Projector Options
• Select Set-up – a number of tabs will appear called pages
• Arrow across the pages (MT850 is Page 5) until an option called “RESET LAMP HOURS” is shown
• Move onto this option and press enter on the projector itself, confirm that you want to reset the counter
• Projector is now back to life

This works for all NEC projectors, the page number may be different though where the “RESET LAMP HOURS” option resides.

The lamp has run out of its operating hours which is normally 3000 hrs. Replace the lamp and you will be alright.

I had the exact same problem and solved it. After calling NEC tech and getting no help, my son and I decided to:

• Remove, clean and reset lamp.
• Completely clean (with compressed air) system.

And it worked. Here's what we did.

• Removed lamp and cleaned with compressed air (in cans).
• Used two cans of air to completely remove all internal dust. In our case long over due.
• Reinstalled lamp and reset meter. (To reset: Turn on machine, wait 2 minutes or so, then hold down the "Help" button right next to the infrared sensor on the front of the machine).

Works fine now! Dont know if it was technical solution but solved it for us! Good Luck!

Good Day Cawhite;
You replaced lamp and still get flashing light.
1. TV's 'ballst may be bad.
2. If lamp comes on for 2-3 seconds, the problem will most likely be the caps in the power supply. (to see lamp turn on you have to take off back or front (inner panel).
Hope this was helpful.
Good luck, Big Irish.

Replacing the lamp with an old one was helpful for me. Good news: the projector itself not faulty. Bad news: I have two projectors with the same issue at the same time (the lamps were replaced also at the same time) after only 400 hours of running.

Did you cancell the bulb fault status in the main menu ie bulb hours when you changed your bulbs if not try this turn unit on and see if it works it may do.

To reset the lamp hours counter press and hold down the Volume minus button - , then press the source button whilst still holding down the volume button for 5 seconds .

If this works you can then verify that the lamp counter was reset by viewing the counter in the status window in the OSM

hope this helps... Regards Vortash
