Hi clwhittaker

Try holding in the Fn ( function ) button and pressing the key in the F-row of buttons that's got one or two screens on it. This pushes the signal to the Projector.

No source found - please check signal cable


Well...first check the cable and replace it if you have one. If you can try a different input. Make sure the proper input is selected on the projector.(if you are plugged into input 1 make sure that input is selected for viewing).

"No source found"


Have you tried another laptop? You might also try hdmi if you can. Many times this is the mother board of the laptop. In windows 7 use the windows and P button?

Casting a blue tint


This could be for a variety of reasons.

First, check all your connections to make sure everything is connected properly and undamaged. If you are using a VGA cable/computer cable, make sure the pins are not bent.

Next, check the cables themselves. I do this by flexing the cable back and forth, starting at one end and working my way to the other. Go slowly and make sure to do this every few inches. If there is a damaged wire, this will cause the image on the screen to flicker or change color. Any damaged cables found should be replaced.

If this does not work, try removing individual cables and using a different one. Do this one cable at a time in order to try and identify where the problem might be. This is assuming you have spare cabling.

If everything is connected properly and nothing appears to be damaged, go into the projector menu and check all your color settings. You'll see you have a variety of options. If these are set to default and you still have discoloration, the problem is most likely internal and may require a technician.

One additional option is to check the data source to make sure all the settings on that are correct as well.

I can't get a picture when I hook my projector up to my laptop.


HELLO,

If your LCD or DLP projector displays no image, this could be a variety of problems. First, check that the projector has power. On the top of the LCD or DLP projector should be some lights. With power, those lights will be on. If it has power, check to make sure that the projector lamp is firing. If so, go to the source. Make sure that it is connected with a VGA cable or USB cable to your computer, or with an RGB cable, S-Video cable or DVI connection to your VCR/DVD Player. From a laptop computer, the VGA cable should be connected to the VGA out connection, and into the VGA in connection on the projector. Are both ends tight?

If everything has checked out so far, the solution probably lies with the external monitor port. Check this by holding the Fn key on the keyboard, then press the F7 key. (On some computers, the key might be F5 or F3. Try these if F7 doesn't work) Each time you press the Fn / F7 combination, you will cycle your display through the following settings:

* Press Fn / F7 once: The laptop screen only
* Press Fn / F7 twice: The projector port only
* Press Fn / F7 three times: Both the laptop and projector port
* Wait a few seconds after each time you press the key combination to let the LCD or DLP projector refresh. Nine times out of ten this will result in seeing your projected image.


Hope this helpout....

Projector signal goes bad after 25 minutes


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.
