    Will have to try this later, my dinner party is starting (where of course I wanted to use the projector)

  • PhilatCBS Nov 01, 2008

    We did all that and sadly it didnt help. Somewhere a user comment describing similar circumstances reported the main board may be fried and need replacement. Oh, joy. Now to find someone who services this equipment.

The universal cord, one end goes into LCD the other into computer, the end going into the LCD needs to be wiggled a lot to get the connection to work. Will a new cord solve the problem?


Does the universal cord go into the rgb1 , rgb2 or S video input.

if it's the rgb input, swap to the other rgb input.
otherwise borrow a cable from the neighbours computer and try that.

if the wiggling is still needed then that socket on the LCD has dry joints on the pcb inside

My Canon LV-5210 displays no image for my computer. It has worked fine in the past. And it did not work a couple days ago and then it worked OK yesterday when we accidentently pushed the Input buttom. But...


If your 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 / F2 or F2 once: The laptop screen only
* Press Fn / F2 or F2 twice: The projector port only
* Press Fn / F7 or F2 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.
this should help you :)

I get a blue screen on my misubishi sl1 projector lamp and no signal appears on the screen


Hi

Make sure the Computer Input is set to VGA, Computer, or RGB (depending on which projector model you have).

There are also known known hot-key combinations used to switch the laptop to its external VGA mode. If you are using a laptop.

Check the cables as well if properly connected both on computer and projectors end.

Hope this helps

I've connected my laptop to the projector. It displays the image for a second and then displays 'Analog RGB searching'


Try setting the projector to VGA instead of RGB input if you can, you should be able to toggle though input modes.

Make sure that the resolution of the laptop is equal or lower to that of the projector.

If you are connecting to a laptop then you may need to hold the function button down and press F1, F2, F3 etc. there should be a sign with the latop on there and a sign with an external device (monitor,PROJECOR)
hope this information was useful to you.

Delay/ whitescreen when projecting video from laptop


1.
Connect the external display port on your laptop computer to the projection system, and then turn on the projector. For information about connecting external devices to your laptop, see the documentation for your laptop computer.
1.
Set the display resolution of your laptop computer to match the resolution of the projector system. First, on your laptop, open the Display Properties dialog box by using the Display icon in Control Panel, and click the Settings tab. Then, in Screen resolution area, move the slider to adjust the display resolution of your laptop. If you don't know which setting to choose, try 800 x 600 pixels; this is a common setting for many projector systems. YOURS sounds like 640x840.
3.
If you have audio in your presentation, connect a cable from your laptop's audio output jack to the audio input jack on the projector, and then test the volume by playing a file that contains sound.
4.
Start the Player on your laptop. If you want to only display the Player on the big screen, and not the desktop background, maximize the Player or set it to play your video using the entire screen (full-screen mode).
