When projecting pictures from the computer, the projected image is much darker than that one the computer and the colors are not true to the original. I've tried pressing the menu button to access the OS display, but nothing happens

hi, first of all check the tint setting on your projectors picture menu. if not get the correct color then, your projector is a dlp projector that means it have a color wheel in side. if the synchronization of color wheel is not correct this problem can occur. there is a sensor for couting the rpm of color wheel. also have a black mark on the color wheels rotating portion. the sensor scene this black mark for making count. if there is any dust in that portion it will make difficult to the sensor making the counts. you have to remove the color wheel to clean the same. i have added a video how to clean the color wheel . not the same projector. ok
If possible, try to replace the VGA cable between the projector and the computer. A bent or broken pin, or a damaged wire, can prevent the blue or green (or both) portions of the picture from being displayed. The result is a reddish/pinkish picture.
As for the long time to project an image, this could be an extended warm-up time. How old is the bulb in the projector? Does the projector have an option to display the hours used and/or remaining on the bulb? Bulbs do have a finite life, and when they near the end of their service life, they can become more difficult to start.
how to make a templates? designing your ouwn templates depends on your creative immagination but a simple techniques for you to have is to know what particular project you are dwelling on. example: Proposal project of Housing Project, Now think of the main subject in the project.... yes it should be housing you draw sketch plan using your graphics softwares or just simply take a snap pictures on the main subject put little tricks in the photoshop if you do have. change the opacity to a lighter one make sure it's not too light because darker colors in the powerpoint (i mean in background) gives better looks. that's it you've than the first step. save it in jpeg or bitmap formats in lower size. browse to your powerpoint programs, choose it as your background templates.
If you're trying to project video, then the unit needs professional service. If you're trying to project from a computer, you may have a loose display cable, broken pins in one or both ends of the display cable, or broken conductors (wires) within the display cable. The computer sends its image information as a template of RED image components, GREEN image components and BLUE image components with the projector overlays to create the complete image with blended color values. (The computer also sends HORIZONTAL and VERTICAL synchronization signals, but those don'e affect the color content of the projected image.) That's why I'm suspicious of the display cable, conductors or pins.
Here is the manual: ScreenPlay 4805 ScreenPlay 4805 Check page 38 on picture settings, you can revers the image to project from behind a screen (mirror), I don' think you can have picture upside down (180 rotation) using projector settings. You need to reverse image source (eg. picture on computer).

If you can nvigate to the On Screen Display Menu, you should see an "all images" section on the main menu. There you will find brightness, contrast, color temp, white intensity, and gamma controls. You should be able to make adjustments from that menu to sharpen and brighten the image.
