Just a shot in the dark. this reminds me 'bout a problem with a Optoma (or maybe it was a Ask) i fixed. In that setup menu (on the proj), i was able to adjust the sync signal on the input. (I don't mean the the screen refresh rate..)  Just tried gradually step by step. Worked then!

When i connect the projector to my computer, all it says is no input selected. i need help with this IMMEDIATELY!!!

make sure the computer has the output screen signal enabled on the external rgb connector. you can confirm this by connecting an external lcd monitor to the pc. swap the pc vga output to the projector.
then make sure the vga/rgb input source is selected on the projector.
also select the lowest resolution on the pc to start with. when a picture appears on the projector, then increase the pc screen resolution until it says it's not able to show it, and back off to the last setting that worked

Projector comes on, everything seems to work, wont recognize any inputs when they are plugged in, says that there is " no inputed detected"

There are several input that you will have to select. RGB for input from computers. There are also video imput selection if you plug it into a DVD player.

Hitachi projector cp-s318 and the pictures give off a red tint.

Hi,

Make sure the Computer Input is set to VGA, Computer, or RGB (depending on which projector model you have). Go through the menu settings of your projector.

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.

I've connected the projector to my laptop using the VGA cable as stated in the manual. The projector reflects as it should, i can access the menu and input options which i then select RGB scart (though...

Not with any RGB input options, computers are not compatible with these. The projector needs to be set up to receive VGA. There must be a toggle button or menu entry somewhere on your projector that lets you do this or why would it have a VGA input?

Color shift blue tint

This could also be a setting. If you are using component video as a connection, make sure that the unit is set for RGB if coming from a laptop or other computer system. If the projector is set to YPrPb, the picture will look purple or bluish as you describe. Change the setting to RGB and all should be well.

I can't project my image from my laptop to the projector..

A usb cable will not work that way--on your projector, it's used for data...you need to obtain a monitor cable which will plug into the vga connector on the laptop and into the connector on the projector (rgb in 1) or (rgb in 2) If you use the #2 rgb input, make sure the button IS NOT pushed in! If it is, the projector will be switched to OUTPUT mode on the #2 connector. Also, on the laptop, normal operation is "laptop only"...when you push the <alt F4> buttons, it should then switch to "laptop + external display(projector)", another <alt F4> push will give "external display only" mode. Then, another push will return you back to "laptop only". NOTE: Sometimes, you have to turn on the projector first, then immediately turn on the laptop--not to get technical but different equipment can get finicky about syncing up...just something to be aware of...
