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.
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.
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.
