Question about NEC USHIO PROJECTOR LAMP, Projector Lamp FOR MT600/MT800 AND MORE, 250 WTS, 2000 HRS => Model 500084

Open Question

NEC MT800 just shows vertical and horizontal lines when started.

The projector projects red, blue, green and other colors vertically and horizontally. At times the colors will change randomly, and sometimes its a white screen, it never stays the same color for long. The menu bottom does not do anything change the screen at all. I looked at the service manual and could not pin point the problem so I'm not sure what to do.

Any help would be appricated!

Hi 80camaro

You could check in the Service Menu if your RGB is the same percentage and at the same run rate.

The run rate is normally 45-60 and the percentage on 50.

I would however recommend that you take it to a NEC agent to get it serviced.

If this doesn't fix it , then you will be looking at a new Mainboard.

Thanks for using Fixya and good luck.

My projector has lines on the screen. new bulb didn't help


If this projector is connected by Component Video (3 or 5 wires) instead of HDMI, the most common color related problems are caused by having one of the 3 video cables (Red, Blue or Green) with a bad connector. If everyone is a green smurf the problem is with the red cable. If everyone is a red smurf the problem is the blue cable. If the green was bad you wouldn't see anything.
Another possibility is if the green is plugged into the yellow jack instead of green jack on the projector, you could see what you are describing.
If everything checks out, take the projector to a repair facility.
If you are connected by an HDMI cable, (combined with the fact you mentioned vertical lines not horizontal) then take the projector to a repair facility.
All of this assumes that you don't just have a bad Cable Box or Blu-ray player or Home Theater Receiver. (The source)

How to set convergence on Projection TV ' s


I have given an general explanation on most projection TV ' s

  1. Enter the menu on your TV. Use the remote control and bring up the menu.
  2. Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
  3. Select a color. You will have red, green and blue to choose from. Do each one, starting with red.
  4. Press "Enter." A crosshair pattern will appear on your screen.
  5. Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.
  6. Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair.
  7. Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.
  8. Repeat these steps for all colors.

hi, sounds like a convergence issue. try this...
  • Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.

  • Enter the menu on your TV. Use the remote control and bring up the menu.
  • Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
  • Select a color. You will have red, green and blue to choose from. Do each one, starting with red.
  • Press "Enter." A crosshair pattern will appear on your screen.
  • Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.

    NEC LT35 color problem


    If you're trying to project video, then the unit needs professional service. If you're trying to project from a computer, you may have a loose display cable, broken pins in one or both ends of the display cable, or broken conductors (wires) within the display cable. The computer sends its image information as a template of RED image components, GREEN image components and BLUE image components with the projector overlays to create the complete image with blended color values. (The computer also sends HORIZONTAL and VERTICAL synchronization signals, but those don'e affect the color content of the projected image.) That's why I'm suspicious of the display cable, conductors or pins.

    Green horizontal deflection


    Change both STK convergence IC's for reliability. They amplify/control both horiz and vertical. re-align after replacement.Locate them on the largest heat sink in your set!

    NEC MT800 Projector with Vertical Lines in picture


    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.

    Convergence not lining up


    Sounds like the green is out of focus. If the focus control for the green does not control it enough to make the width the same as the red, then, the lens on top of the green can be adjusted to focus that tube. On the lens, there is a wing nut on a screw to loosen it and move the lens left or right a bit to help with the focus. Hope this helps.
