My canon eos rebel k2 will not turn on even with brand new batteries in it. What could be wrong?

hello, maybe, you have the contacts of your lens or your camera with dust.
this make what the camera works wrong,

you have to clean the contacts of your camera an lens with a Rubber to erase, and the camera must be ok

The Rebel K2 has the Canon EF mount. It is compatible with any EF lenses except the EF-S series. It will also work with third-party lenses that are compatible with the Canon EF series.

You can see the entire current line of Canon lenses (including the EF-S series) at

Not really, no. Assuming you've already tried the obvious of new batteries and checking that the battery and camera contacts are clean then there's nothing more you can do.

Diagnosing any completely dead electronic device is difficult, time-consuming and needs specialised test equipment. If you had the skills and equipment you clearly wouldn't be asking here so that leaves you just the professional repair option, but any professional repair will be uneconomic given that 35mm Canon Rebel/EOS triple digit models are worthless these days.

It's not all doom and gloom though, because they are worthless it also means they're relatively easy to get for free from places like FreeCycle and Freegle or even just by asking friends and neighbours. As all surviving 35mm Rebels/triple digit units are long past their maximum design lifespan you'll probably find that many are faulty, but I've been lucky so far and the only faulty one I've had was just a broken zoom lens.

That is the roll rewind indicator and when flashing usually means it is okay to open the camera and remove the film roll. Here is your manual online: http://www3.canon.de/images/pro/fot/slr/geh/file/eos3000v_INSTR_ENG_toc.pdf

To resolve the annoying "change the batteries" problem. Goto menu, choose yellow menu, select
file No. reset to ON. Turn camera off and back on.

Voila fixed.

Canon also uses the low battery Icon as a generic error code. Try taking the lens off the camera. If this fixes the problem the lens needs a repair (most likely the aperture unit). If not then the camera needs the repair (either the shutter or dc-dc converter circuit).

guido462:

new batteries - brand new? fully charged per spec?

That all depends on what you have your settings for. If you are not using the program mode, you'll need to make sure to check your Aperature and Shutter speed. Adjusting these might make your pictures come out better. Make sure to check your light meter, the needle or indicator should be in the middle for best results.

The shutter is most likely damaged.

If this camera is a Canon Rebel K2 the problem may be that it might need a new main drive motor. I have replaced two drive motors in the last couple of days in these cameras. When the motor starts to go bad the film transport may stop in mid cycle and the battery check indicator starts to blink. The battery draw becomes excessive and the camera shuts down. Of course, there may be other problems but this a common one. Hope this helps.
