A610 flaky on/off button, opening it up...

[pmin00]

Hello,

for about a month now the on/off button on my Canon A610 has
been misbehaving: it sometimes takes 20-30 presses before it
switches on. Unfortunately my warranty has _just_ expired, so
I decided to open it up to see if I could fix it.

Unfortunately, from the circuit board below the on/off switch, it
looks like it connects multiple lines.. (?) Does anyone have a pointer
to more technical info about the A610? About this piece of circuit
board? A repair manual?

Many thanks in any case,

Patrick

I doubt you'll find such technical information freely availble so it's up to you to find out what, where and how .
Maybe the button is worn out in that case it's best to replace it, takes a few minutes of soldering and shouldn't be to risky if you know what you're doing .

Can you post some pics of the circuit boards ?

ok, I was out of town for a bit, and of course had to find another
camera to take pictures of the broken one...
All pics below were taken with a Macbook onboard camera, which
doesn't do well in low light, hence the poor quality. (The last closeup
was taken with a Panasonic DV402 mini DV camera, which does a lot better)

You need a small Phillips screwdriver, good lighting, and a place to put
the screws so you can label them, and don't lose them.

Step 1: remove the 3 screws from the bottom of the battery compartment (already removed in this pic):


Step 2: remove the 3 screws from the left (as seen from the back) side panel:


Step 3: remove the 3 screws from underneath the "connector cover":


Step 4: gently lift the top off the camera a little bit, and remove the small
flat cable from its connector on the camera body:



Step 5: remove the single screw that holds the top circuit board in place. Note that
you may have to pry the small speaker a bit to get it out. Be very careful here
as several parts are loose after the circuit board is removed.


Here's a pic with pointers to the on-off button itself, and the actual button
on the circuit board, which is just a piece of metal bulging up.


Here's a closeup of this piece of metal. It's attached to the circuit board, and it
is difficult to see which line(s) it actually shorts when depressed...


I guess the next step is to try and remove the metal button to see which lines it uses

I hope this was at least helpful/interesting,
any pointers appreciated,

Patrick

Patrick,

I know this thread is waaaay old but I wanted to thank you for posting the disassembly photos. My zoom switch quit working and by following your disassembly instructions was able to get to it and fix it.

With appreciation,
Da Prof.

Great, glad to know the info was helpful :-)

(I have an A650IS now, by the way, still going strong after 10,000+ pictures)

At first I thought this was a legitimate post, now I realize it probably is spam :-(

Looking at the posting history, probably not spam but definitely an unwelcome sig file. Blueberries, you should probably get rid of that advertising in your sig.

Well, posting the same line twice, which is a copy+paste of a line from the post by 'Professor'...

Ah, I didn't catch that the line was a C&P. Definitely spam.

Yes, I didn't see that at first as well. Strangely enough, his/her other two posts seem normal. Ad links in the sig though. A moderator should delete the posts.
