Canon EOS 350D/XT Power Problem

My camera is about 18mths old and has fired about 7500 shots. The camera won't turn on. A charged battery (around 8.5V) inserted into the camera will drop to 3-3.5V straight away. This is with or without turning the camera on. Tryed with known good batteries with same effect (ie dropping over half voltage). It sounds like there is something inside drawing lots of current. It looks mostly surface mounted devices on the inside so will be hard to trace. Anyone got any suggestions? or a repair manual / circuit diagram?

This is a board comonent failure as you surmised. I doubt id parts are available- it will be a complete replacement board. Check the Canon Support for a repair estimate.

Camera still dead with a new charged battery. Is it possible to overcharge a battery so it won't work?

If you have another battery definitely give it a try, most likely it won't work either. The problem is probably the fuse located on the DC/DC board that has 'blown' causing there to be no power. Replace the board and the camera should work fine. Canon will probably charge $175 or so for the repair.

Hope this helps.

I have a Canon Rebel EOS that I am having trouble power wise with. I can have a fully charged battery in, the power off option off but it still turns off sometimes before I even take a picture. I rarely...

Sometimes it happens that the ends of the battery get torn off while we place the battery into and out of the charger for charging. the battery heads get popped off which most of us dont notice.
i suggest you to get a new alkaline battery and check the same with your camera. If problem resolves go ahead and buy new rechargeable batteries.

No power - fully charged battery

How about cleaning the battery contacts in the camera first with a pencil eraser and then, with a cotton swab lightly dampened with rubbing alcohol.

Canon EOS Digital Rebel XT will not turn on.

It could be a number of things. The first thing you shouild do is remove the back cover and check for loose screws. If you don't find any, the problem may be a damaged battery door switch, a damaged memory card slot door switch, or worse- it may be a defective power board.

Will not turn on

Old batteries will not charge fully. Batteries left to completely discharge will most likely be useless.

NO POWER in my digital camera

Could be your power circuit. You may contact Canon direct in Jamesburg, NJ or take it to an AUTHORIZED service center for faster service. I know of one in Flordia 305-653-7355

Camera drains charged batteries

Most likely your batteries are just not holding a charge. However, before you spend good money on new batteries, try charging them on another charger (friend or sympathetic photo shop?). Could be the charger also. Usually it's the batteries, though.

No Power To Canon Digital Rebel XT

Change out the CR2016 3V battery. You have to remove the rechargeable battery to get to the CR2016. Refer to the manual for proper instructions.

Had the same issue with a two year old camera. This solved my problem.
