I found this too:

Maybe I try to open up the camera and clean it better:

And I will ask Sony repair what the cost will be, if a 580 repair is still possible. I will not buy an other 580, maybe a A68 is a nice replacement.


The A580 startup problem seems very common. Both of my A580s have it, to varying degrees. I have used contact cleaner on both of them several times, but it only produces temporary improvement (if at all).

The worst result happens when the power loss is during an exposure. The aperture motor dies and causes the camera to throw a "camera error" because the aperture lever is stuck closed. Sometimes the error will clear but, on a couple occasions, I have had to take off the lens and manually move the lever on the camera mount back to the open (large-aperture) position.

I don't think steady-shot figures into it. Turning it off would probably slightly reduce electrical current draw, which could might cause it happen slightly less often. I have also noticed that using the internal flash makes it slightly more likely to happen for the same reason.

Using the cleaning methods only produces only temporary relief (for me). It might sometimes help with skipping control wheels, though.

I would recommend getting a new-ish SLT camera. My A580s still work most of the time, so I keep them around for an occasional shot. I don't really depend on them, though.

Mine would power up fine. Then when pressed shutter release it would power off and restart. Sometimes would work fine for ages then other times be every few shots it would power off and restart.
Couple of times it would lock focus then without releasing shutter release would move focus to infinity.
Been thinking about getting it repaired. But upgraded to an A77 instead.

I have contacted Sony repair, they have outsourced there camera repair. This technical center that I have contacted next told me they don't have spare parts for the 580 anymore. I guess in general, not specificly for this problem. They told me the problem is the on/off switch.

I read the A77ii is a superb camera. I will think about it. Until then I can still use my problematic 580, I should use is it more anyway.

edit: I resprayed the on/off switch with contact spray, camera is working again with no problems, for the time being. I keep the camera turned on and let it sleep with auto power off after 1 minute, maybe it will help when I don't touch the on/off switch anymore. Time will tell....

An update, just finished the repair by myself.

Inspired by this pictures I opened up the camera

https://www.flickr.com/photos/valleyimagery/11678615285/in/photostream/

and the service manual

https://servicemanuals.us/sony/digital-camera/dslr-a560-dslr-a560l-dslr-a560y-dslr-a580-dslr-a580j-dslr-a580l-dslr-a580y.html?limit=4&start=8

I almost had given up, because the front cover is stuck behind the tripod screw at the bottom. The front cover fits really tight, I was afraid the plastic would crack.

But with assembly I dropped a little screw inside the chassis, so I had to open it up anyway to get the screw back, pulled with force and then it opened. Had to remove a lot of screws. Be aware the bottom screws are shorter. And to put away the front cover I had to remove the DOF button.


I removed the aperture wheel, and then blow with compressed air between the shutter button contacts, I created some space with a screw driver between the contacts. And then I sprayed a lot of contact cleaner in this area.



I tested the camera a lot of times, and then put it back together. I have no screws left over, that's a good sign. And no scratches or damaged plastic.

So far so good, hopefully this is the cure. With this experience a future inside cleaning of the contacts is an easy job.

Thanks for sharing this. The service manual link is very useful, too.

I hope the repair holds up. I have given up on spraying contact cleaner into on/off/shutter switch. Opening it up like you did has a better chance of working, I would think.

I have retired one of my A580s because the misfires just made it too unreliable, and the resulting aperture motor occasionally sticking just compounded the problem. So now it is a parts camera. My other one works most of the time, but is still prone to the intermittent power problem. I have pretty much moved on to using my A77's and A99 most of the time. I find them to be generally more versatile cameras, but the low-light ability of the A580 is still sometimes much appreciated.

My camera feels like new with the cleaned contacts, for the moment.

Cleaning from above is not enough, the spray can't fully reach the power button and shutter button contacts.

You should do it too, nothing can go wrong, just don't drop screws inside the camera. Take care when you do this with the assembly at the end, turn the camera in a position the screw can not fall inside the chassis if it slips. The irony is if i didn't had dropped a screw, I wouldn't went further with the repair. So I am glad I dropped it. Maybe it was a sign from above or something :-)


Opening up is not very difficult. This is what I did:

-unscrew the topcover. Keep the bottom screws away from the rest, they are shorter
- unscrew the bottom screws from the backcover too, to create some play or space, you need this for the next step
- pull away the top cover, and the problem is the cover is fixed around the tripod mount. You have to pull with force, and also pull up the plastic so it will slide over the tripod mount. This is the difficult part. I thought I had forgotten a hidden screw or something, but it fits just tight.
- unscrew the DOF button, to prevent the cable will break, and put away the front cover.
- unscrew the board with the capacitor with 4 screws, to create some play, you need this for the next step
- unscrew the metal plate that holds the aperture wheel, and pull out the wheel, and bend it away (it is still connected with some cables).
- now you can reach the shutter button contacts and power switch. I used compressed air to clean between the contacts, and I made some space between the contacts with a flat screw driver.
- clean this area with contact spray, and work the shutter button and power switch.
- let it dry
- assemble the aperture wheel and put the screws back on the capacitor board
- check your camera, everything still ok?
- assemble the DOF button
- put the top cover back, all the screws in place.
- job done.

It is not that difficult, takes 30 minutes, just work systematic, on a clean space. Don't drop screws in the camera, or on the floor like I did. Make pictures with your phone at each step for reference. And don't touch the flash capacitor, service manual warns you for this, there could be 300V inside. But this will not happen, no reason to touch the contacts. And take care for the mirror, you have to pull the top cover, you need some grip for your hands.

The power and shutter button is fixed with a spring, for a short moment I had the idea to dissemble this too. But I think you can't assemble it back again without dissemble the top cover, with the mirror box and viewfinder and other important parts. I guess then you really are in trouble and wreck your camera.

I did some SRT101 repairs back in my analog days, and that was way more difficult with wheels and ropes inside, and springs that jump out and are difficult to get back in. With electronics I always have the feeling I ruin something by touching contacts and electronic parts.
