Projector signal goes bad after 25 minutes

Our church uses a Dell 1400MP projector. We use two sources for our dvd need, computer and dvd player. We never have a problem with the VGA source on the computer. After the projector has been on for 25 minutes, the image from the dvd player source develops over a dozen vertical white lines.

We have switched out the dvd player and tried s-video, video composite and RGA component cables. I just don't understand why the signal from the computer will still work. I thought it might be a fan issue or a mainboard issue.

It appears the projector was over heating. Why it affected the DVD signal and not the computer signal, I do not know. The other confusing thing was the projector was hanging off the ceiling and should have had plenty of circulation. When I climbed up to check for excessive dust, I found that the lens cap had been placed over the intake vent. I blew off the dust and removed the cap. After running the projector for an hour, it appears that the problem has been solved.

My projector screen go green blue Red than blank nothing else.How can I fix it?

If your projector screen is displaying green, blue, and red colors before going blank, it indicates a potential issue with the projector's color processing or signal input. Here are some steps you can take to troubleshoot and potentially resolve the problem:

Check the video cables: Ensure that the video cables (HDMI, VGA, etc.) connecting your video source (such as a computer, DVD player, or gaming console) to the projector are securely connected at both ends. Try disconnecting and reconnecting the cables to ensure a proper connection.
Verify the video source: Confirm that the video source is functioning correctly. Test the video source on another display device (such as a different projector or a TV) to ensure it is providing a proper video signal.
Adjust the color settings: Access the projector's menu or settings and navigate to the color or image settings. Ensure that the color settings are properly calibrated and not overly saturated or skewed. You may need to adjust the color balance, hue, or saturation settings to achieve a more accurate color representation.
Reset the projector: Some projectors have a reset option in the settings menu. Try performing a factory reset or resetting the projector to its default settings. This can help resolve any software or configuration issues that may be causing the color problem.
Check for firmware updates: Visit the manufacturer's website for your projector model and check if there are any firmware updates available. Updating the projector's firmware can address known bugs or issues and improve overall performance.
Test with another video source: Connect a different video source (such as a different computer or DVD player) to the projector and see if the issue persists. This can help determine if the problem lies with the video source or the projector itself.
Contact technical support: If none of the above steps resolve the issue, it may be necessary to contact the manufacturer's technical support or a professional projector technician for further assistance. They can provide specific guidance based on your projector model and help diagnose and fix the problem.

What connections do i use to connect projector to tv?

You don't connect a projector to a TV.

A TV doesn't have the capability of supplying a source signal to another device. It can only accept a signal and display it itself. Connect a DVD player/Blu-ray player/TV receiver/Games Console to the projector directly via the AV sockets.

Use a separate sound system if you need more volume than the projector's tiny built-in speaker can provide.

Projector takes 30-40 min to recognize signal from elmo 110xg

the resolution might not match from presenter to projector. are you using rgb, composite or s-video? the signal might not match. there might be an auto adjust on the projector to read and match the elmo's resolution. if not, the elmo may have an issue sending a powerful enough signal to the projector, and need a new main board.
