Having problems with your Canon PowerShot A640 Digital Camera ?

My canon powershot a640's flash isnt flashing.

\015 I have Flash turned on and when I try to take a picture, all I get is a orange light and the flash icon blinks on the screen.\015

Answers :

I can't believe I just managed to fix exactly this problem on my camera.  Warning - the process hurt somewhat, but it did work.\015\012
\015\012I dismantled the case very carefully:  After taking the shiny grey cover on the screen end off (3 screws, noting carefully where each screw was), I took the top cover off.  \015\012
\015\012That was a case of unscrewing three screws at the bottom of the battery compartment (I left them in place, as it looked tricky to locate them again, subsequently working with the camera upside down), then gently prising the top off - there is an internal clip just next to the visual viewfinder, which you have to wiggle a bit - just use a fingernail to prise it open.  The top lifts off - dangling on with its cable.\015\012
\015\012Here is the unpleasant bit.  Quite accidentally, I shorted the flash capacitor, by touching its circuit board - and got the most surprising electric shock.  \015\012
\015\012I looked around to see if there was anything else I would be able to do, felt there wasn't, so I put it all back together, in the hopes that it might have fixed my problem.\015\012
\015\012Hey presto, I now have a working camera with working flash!
I read the posts by weisendesign and johnathan222 and thought that before I took my camera apart in hopes of fixing the flash I would try giving it a solid tap on my palm in hops of knocking things back in place. It is almost 4 years old and not much good to me with out the flash so I thought "Why not." Two solid taps and the orange light came on when it should and two more and the flash worked. Thank you for the info.

PowerShot SD300 New to this stuff but flash isnt going off at all. Taking pics outside works perfect or if there is enough light.....Just called Canon and they were not that helpful at all. Told me i can send in at my expense but probably would cost about $90 or more to fix and/or I can upgrade my camera (for models that are older than I can get for under $200....they want to offer them at $150). Anybody have an issue with the flash not going off? the only thing the canon buy told me is there mi

Just had my Canon Powershot s1 is flash explode in my face at a meeting with over 30 people attending. I took a picture, the flash went up and suddenly it popped so loud that people ducked. There was also a fire/smoke smell coming from the flash area. Very scary. Those witnessing said they would back me up if suit filed. Checked the batteries and they work fine. The camera will take pictures still but without a flash. Hear of anything like this before? Recall issue?
