Question about Sony Cyber-shot DSC-T77 Digital Camera

1 Answer

My camera turns on by itself even with the slide in front in the closed position. The screen then shows the warning that the lens cover is closed. When I open and reclose the lens cover in 10 or so seconds the camera turns itself back on and repeats with the lens cover closed warning. The only way for me to turn the camera off at this point is to remove the battery. Help!

Most likely some dirt, dust, or other particle is jamming the lens opening gears. You can try to spray some compressed air into the lens assembly, hopefully dislodging whatever is obstructing the lens cover. If this doesn't work, the camera will have to be serviced, which can be expensive. If the compressed air doesn't work, and you decide to have it fixed, get an estimate first. Often the cost of repair justifies going ahead and purchasing another camera.
Good luck, thanks for using FixYa, and hope this helps!

The lens cover does not open all the way. I have to use my fingernail to do it.


It is either bent or has grit and dirt in between the slides. Try using canned compressed air, such as you use to clean a computer keyboard with, to blow air between the slides. If that does not work, even though you will have to be very careful, while the lens cover is closed put a single drop of WD40 on the cover and spread it with a Qtip over the entire cover surface. Holding the camera, front facing down, try turning it on and off several times. If that frees the lens cover, turn the camera off and wipe the surface of the closed lens cover with a soft tissue to clean the WD40 from the surface. Make sure then that your lens is clean before using the camera. If the lens cover is bent, then none of this will work.

Broken lens cover **RESUBMITTED to Corrected Camera Type**


It's not really a problem if the lens cover isnt there. The following actually shows how to repair a broken lens cover. But have a feeling yours may be damaged beyond repair, so the next option is removal of the shutters. Be careful that you don't get any of the rubbing alcohol that's spoken of in the following procedures on the lens itself.

Lens cover


Well, I just looked at one, it is not easy to get to the front cover. Everything is removed from the back of the camera. The display, both circuit boards and the battery compartment have to be removed first. You may do better locating another camera, eBay is always a good start.

Shutter will not close!


very small dust particals are the reason of this problem.I m suggesting an idea but apply it on your own risk.Keep camera in off position then slightly strick with ur fingernale around the lens ring evenly.This can make the lens shutter contrct.Once the shutter closed,clean gently with a painting brush over the edges where shutter slides from.do this for several times so that any hard dust partical causing may removed.do not insert anything inside.

Lens Cover Closed


the switch inside that activates the camera is probably loose, or worse, broken.

Lens will not retract


In my case, there was dust in the switches that sense the cover movement.
  1. Close the sliding door and wait until the lens is drown inside (timeout).
  2. Open the screws that secure the front cover.
  3. Remove the sliding door covering the lens. There is no trick (hidden screws etc) so just use the force. The door is mounted by two-sided tape and adhesive.
  4. Remove the front cover. This is also mounted by two-sided tape / adhesive in the center, so you have to be a bit brave.
  5. The sliding door rails and the movement sensors are now visible. Clean all dirt.
  6. Try the door functionality.
  7. Mount the front cover after the lens works as it should. Close the screws.
  8. Mount the sliding door.
