Off lens,view finder is not workink

The view finder is the little window on the top left of the camera. If you want to use the display as a view finder, you have to press the button with the camera logo. It is called the life view mode. you use the same button to switch off the display. Be aware using the display, will drain the batteries quicker. Somewhat faster then with modern cameras.
see page 19 of the manual.

I have an Emerson EWF2702 model flat screen TV that just developed a remote control signal recognition problem. Is it the remote (w/new batteries) or the IF sensor inside the TV box? Is it a diy fix or...


There is a simple way to check whether your remote is still sending a signal to the TV. The infra-red flashes from the remote cannot be seen with the naked eye, but they ARE visble when viewed through a video camera. It's easier to do this with 2 people, but it can be done by one person with the camera in one hand and the remote in the other. Just point the remote at the camera and press some buttons. If you can't see the flashes through the camera view finder, it's likely the IR transmitter in the remote is dead. If you can see the flashes, it's likely to be the IR receiver in the TV.

I've used an analogue (tape) video camera for this test, but there's no reason why it wouldn't work on a digital video camera or possibly even a digital/phone camera.

Hope this helps.

When looking through the view finder can only see flashing purple

This sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check this link for more info.

A Toshiba TV 27A45 was given to us. TV works fine,but Remote no.


There is a simple way to test to see if you IR port on the remote is working. View the IR port using any digital camera, camcorder or cell-phone camera view screen. Through the view finder, the remote signals appear as a flashing blue light (whenever a button is pushed). Even the old-style VHS, VHS-c, and Hi-8 video cameras can "see" a remote's infrared signal.

Just so that you know what to expect, do this experiment using remotes that you have that you know work OK.

Canon 40D LCD Wont come on buSY flashes in view finder

Okay, this is simple. Your camera can take several pictures at one time in a burst. However when you release the shutter button your processor takes a second to actually SAVE the pictures to the card in the camera. One thing than has helped me in my wedding photography business is to buy the fastest speed cards I can find. It significantly reduced my "busy" time.

"Negative space" flashing on view finder

Try going into your settings menu and selecting the "reset all" option. I have found this fixes many of the oddball errors.
