PowerShot SX740 HS won't turn on anymore

vraclya — Wed, 19 Jun 2024 13:05:36 GMT

I purchased the Canon Powershot SX740 HS and got it in the mail today (06/18/24). When I got it I used the included battery and 64GB SD card and took some photos. The camera then died and I put the battery and camera to charge. Now the camera will not turn on at all and the only indication of it somewhat working is when I insert the battery into the slot and try to turn on the camera, a green flash will go off for a second. It was working perfectly this morning and now it isn’t. Any help is appreciated!!!

i’m having the same exact problem. i recently purchased the same camera and it doesn’t turn on even when the battery is full. it does turn on randomly once a day but once i turn it off it won’t turn back on or the screen will turn black on its own and shut off. i took it to a camera shop to see what they could do but all they tried was a new battery which also didn’t power on the camera. the guy told me it was a defect to the camera but i’m noticing a lot of people have this same problem. if anyone knows what to do please let us know 🙂

Hello vraclya,

Dirty battery terminals can reduce battery performance and cause issues like this. Try cleaning the battery contacts on the battery and charger with a clean, dry, microfiber cloth or cotton swab to insure good communication between the battery and camera. Have you tried using a separate Canon battery? Try the camera with just a fully charged battery, no memory card. Is the unit still not powering up? If so, the camera would need to be sent into our service center.

I'm having the same problem with my PowerShot SX720 HS. It will no longer power on. I tried a brand new (fully charged) battery, I cleaned the terminals with a cotton swab and alcohol, I tried it without the SD card, I tried the hard reset (no battery or card for 20 mins), I checked that the battery door is properly closed, and I checked for lens obstructions. Nothing helped. Has anyone here with this problem been able to resolve it on their own? Thanks!

Greetings,

This thread is a few years old now and for a different body.

Your camera is about 10 years old. It sounds like you checked and performed the usual problem areas and troubleshooting steps. New battery, battery door, etc. Do you know if your charger is actually working? You can use a ohms meter to test DC voltage output. This would help confirm that your charger is in fact working. To test, set your ohms meter for DC. Plug it into the wall and carefully probe the positive and negative terminal without a battery installed. It should read 4.2V to 8.4V. If it reads zero or fluctuates erratically it's the charger. If it shows a stable output voltage, the problem is likely with the camera.
