We cannot see through the view finder of a Canon EOS Rebel G 35 mm camera, and we have turned the camera on and off, changed the batteries, and used different lenses. Can you help with the problem please?

Yes.

There is no on/off switch as such. Press the shutter button halfway to turn it on, and leave it alone and it will power off.

If you need a manual, you can download one from
http://butkus.org/chinon/canon/canon_eos_rebel-x_rebel-xs/canon_eos_rebel-x_rebel-xs.htm

Next to the viewfinder ther is a diopter adjustment so you can change the focus in the viewfinder. this is so if you need glasses the camera can be set for you. Start by focusing the camera on something, then slide to turn the diopter adjustment until it looks sharp and try not to bump it.

how can you download and update firm ware when you cannot see anything on the screen?!!!!

I can help you fix the BUSY Error or Error 99 of your Canon EOS Rebel XS / Canon EOS 1000D.

Installation of this Canon EOS Rebel XS / Canon EOS 1000D firmware version 1.06 update will solve these problems:

1. Some cameras may exhibit a phenomenon in which the LCD monitor does not display, the shutter does not release, and the BUSY indication remains lit in the viewfinder.
2. The message, "Err 99 Shooting is not possible. Turn the power switch to<OFF> and <ON> again or re-install the battery", appears on the camera's LCD monitor, and after the above operation is carried out,the LCD monitor displays in a language that is different from the actual language setting.

Im afraid your camera does not have live view so therefore you will have to use the viewfinder to take your images and view them back on the lcd screen.

The XT does not have a "live view" feature. You have to use the viewfinder.
The LCD is strictly for data and picture viewing.
