I have a hand me down MT830 that i recently tried to get to work and i ran into some problems. When i turn the projector on, it displays the first set of options perfectly clear (video, s video, rgb, ect.), however it shuts off almost automatically within about 4-5 seconds. Can someone please help me out, im pretty much just looking for a quick fix, so if anyone can help that would be great.
If you are tech savvy in the slightest, open the unit up. check to see if all contacts are intact. This sounds like a thermostat error. Make sure the thermostat and the ballast don't have any loose wires. If it isn't connected properly the unit will think it's overheating and shut down.

Restart your computer.
As soon as it starts the start-up process, keep tapping the F8 key, repeatedly.
When you see the Windows "start-up" menu, select "start in safe mode".
Does your monitor work in this low-resolution (640-by-480 or 800-by-600) mode?
If so, then you had configured Windows to a too-high resolution that the NEC did not support.
Choose 1024-by-768, and click "Apply", to test that the NEC supports this mode.
Try connecting the NEC to some other computer, to see if the NEC itself is the problem.
Hello I am an electronics technician from Washington,DC. Try projectorzone.com they are located in Portland,Oregon I have used them several times. Nate was very helpful. You can find a lamp there for sure.
try updating the latest driver for your video and bios. try connecting your laptop to external monitor if both of this didnt solve your problem, i suspected you lcd screen is faulty and need to replace.
l6. After you install a new lamp, select the lamp Usage icon and press and hold
the "Power On" button on the remote control for ten seconds to reset the
lamp time clock to zero.
NOTE: If resetting the lamp clock back to zero after 2100 hours of service,
press the "Power Off" (not "Power On") button on the remote control for ten
go to menu- go to setting -go to colour move slider to right hand direction befor you change the lamp -take care that some vga cabel(((cabel between pc and projector make this fault).then you have to change this cabel and try.
Their are adjustments on the main video board of the projector for alignment of the three LCD screens, But these should only be made by a qualified professional as they can make it worse if done wrong.
First I would suggest cleaning the filter on the bottom of the unit where the fan inlet is. Over heating can cause many issues with the video controller in the projector, also shortens the life span of the bulb, always let the unit cool down when turning it off (let the fan run when you turn the power of by top button, never unplug and use the power switch on back. until the fan shuts off.)
The ghosting problem is a combination of both the lcds and driver boards in which case neither need to be truely replaced.. They use a specific voltage to transmit data to the lcds.. Each lcd is different and the driver board is programmed by the factory for the EE v.com setting. Unfortunatly with nec, they do not offer a service mode to go in and adjust the ee settings to correct the electrical convergance. So the only way to fix the problem is to replace the lcd with a newer one who wasnt worn out from long term heat.
