How to fix a sticky lens barrier on Canon A530
Do you have a Canon A530 (or A510, A520, A540, A550, A560) like this:
Sticky lens barrier is a quite common problem. It would be caused by split milk or juice, or dirt. When you turn on the camera, the lens barrier won’t open fully. It’s different from a lens error. In this case you can operate the camera just like normal, but you might get only half picture with black shadow, sometimes maybe almost total black because the barrier won’t open.
To fix this problem we need to prepare something:
a tweezer with serrated points, a 1.5 mm flat screwdriver, some wooden Q-tips, isopropyl alcohol, Super Duster(compressed air), double-sided tape, scissors, knife.
Let’s make a spacial tool first. Cut a piece of wooden Q-tips as shown on T1:

Step 1
Turn on the camera, let the lens extend out then open the battery lid, take out the batteries. Let the lens on extend position. Hold the lens body, insert the wooden tool we just made into the gap and turn it slowly to separate the ring.
Now you got the ring off.
Step 2
Insert the batteries and turn on then off the camera to retract the lens. then remove the batteries.
Insert the flat screwdriver into the slot(1) about 3-4 mm depth, gently pry on (2) direction a little bit, use tweezer to give a little help on (3) and lift the barrier cover up(Figure 5 will give you the idea). Same on the other side to take cover out.
Step 3
Now take out the barrier plates. Use the screwdriver press the spring post to prevent the spring jumps out when removing the small plates.
Step 4
Clean the barrier cover and plates with Q-tips and alcohol.
Step 5
Remove two springs, clean the lens body with Super Duster. Clean the plate posts with alcohol if you got juice on them.
Step 6
Now put the springs back.
Put the screwdriver on the post(1) of spring to prevent the spring from jumping away. Move the spring into the right place(2) carefully.
Two springs are in place.
Step 7
Put back the big plates.
Put back the small plates.
Press and hold the small plate slightly, move the spring to the place shown on red.
Now we got all the plates in place.
Put on the barrier cover and press it down gentaly. You can feel a click when it gets in.
Now you can put the batteries in and test. If nothing goes wrong, you should see the barrier open and close perfectly.
Step 9
Clean the lens ring.
Turn on the camera and remove the batteries, let the lens out again.
Cut four small pieces of double-sided tape and tape them on the barrier cover.
Check carefuly, don’t let the tape touch any plates.
Put on the ring to match up the index, hold the lens body, press the ring carefuly to make the ring taped on the barrier cover properly.
Voila! We got all the job done.



















Awesome! I followed the steps you provided and was able to completely clean my A530 lens (that went deep into the middle of a birthday cake). It now works as if it were new, thank you!!!
Thank you for this. Saved my life. Able to fix my mothers camera and working like new again.
Thank you very much for these instructions. The spring slipped off one of the small barrier cover plates of my A340 , causing the mechanism to jam. Thanks to your instructions I was able to remove the outer ring and barrier cover , reposition the spring , blow out the dust then reassemble the barrier cover and outer ring. The Canon A540 now works fine.
Hello,
I have a powershot a520 and the lens cover won’t shut, but the lens won’t extend upon power up. The LCD screen won’t turn on either. I thought it was simply the lens cover being obstructed causing the lack of full power up. When I press power, the little green powered up light turns on, but the camera doesn’t extend nor does the LCD screen turn on. After a little bit, the camera makes a little ringing sound and turns itself off (and then the little green light goes away). Any ideas would be much appreciated!

Try to press the PLAY button see if you can turn on the LCD. If the LCD can turn on, mostly you got a jammed lens.
Thanks for the great instructions and pictures. I skipped the double sided tape but didn’t clean off the glue either. The ring seems to be holding fine. I will keep an eye on that and follow through with that part of the instructions if there is a problem. I was lucky too because I blasted it with air without removing the springs. They held until I got a slightly magnetic screwdriver close and the spring jumped off. Then I realized the risk I had been in of losing a spring.
Amazing how well it works now considering during the whole operation I couldn’t see any dirt or grease. Yet it must have been there because after cleaning it worked perfectly the second time I powered it up and still does. My knock about camera is back. Thanks.
Oh yah: I my wooden tool kept splintering but I had a thin nylon guitar pick handy. It worked much better for removing the ring. No creasing.
Thanks alot… took a while with my fat fingers getting in the way and almost lost a spring but the cover is working again!!
Hey, i was taking shots of the surf and i had the cam.( olympus fe-370) in my pocket which had sand in it. And there is sand where the lens should extend. She won’t budge, what should i do?
