Toshiba 3LCD Projector - No image from the computer
I am unable to project images from laptop via my projector. The green lights come on when the projector is switched and the Toshiba logo is projected on to a screen. However, the computer does not seem to be recognised by the projector or vice versa. The projector light is on but does not seem powerful enough. What is wrong ? Do I need to do something?

It could be a broken connection in the computer lead for the red signal, or a fault on the projector that the red panel doesn't work any more.
To diagnose, bring up the projector's on screen display. If there's white in the menus then the problem is the cable. Replace it with a new one. If the menus are affected too then it's a projector problem. This requires the attention of a service engionner.
Most of the time, when an image is cut off the problem is coming from the source.
I assume you are using a computer connected to the projector? Try using different resolutions in your computer's settings. If you are using Windows, right click on your desktop (away from any icons) and go to screen resolution to make the changes.
Alot of projectors (being all projectors that are designed to be hung from a roof) have an image flip function. This is because when you install a projector in a roof you have to flip the projector upside down so the projector doesn't have to be pointed down and doesn't cause any problems with keystoning.
If you have just bought a new projector and installed it in the roof or perhaps bought it second hand and are projecting from the floor (when the previous owner may have had it in the roof), you will need to go through the menu screen until you find this setting. I don't know exactly what Epson call this function but it should be in there somewhere. If you have it on the floor you want image flip off, if you have it in the roof you want vertical image flip on, horizontal image flip is for when your projecting onto a special screen surface from behind the screen.
three green lights come on then the standby light goes red and remains on when the projector is plugged in. The lamp and fan do not come on when the power button is pressed instead the lamp light comes on red.
Many Hitachi projectors use 3LCD technology which supposedly makes colors more realistic. 3LCD means that the projected light must pass through 3 seperate LCD screens. Each screen has one color but when mixed, they form a nice picture. I would guess that one or more of the LCD screens have gone bad. That is a hardware problem that I would recommend talking to the manufacturer about.
hi try using the function key to toggle the display output form the laptop.every laptop when connected to an external display like projector works in the multiple diplay mode.in this mode the laptop vga output can be seen in 3 modes------ only laptop screen, only external deipaly(projector) & both laptop & projector.check this & this should work fine
