Lens cover closed - inside photos? (Sony DSC-T7)

And once again this problem is showing up on this wonderful forum.. I read all the post regarding the same issue, and I gently took off the front cover and I did discover the loose plastic part, only that when I touched it, the small plastic part, the part covering it and a tiny spring under the plastic part came off... are there any photos of how the parts have to be put on it or can somebody give me a description, please?

thx in advance.

Hey guys. I came looking for a solution to my problem as my camera was doing the same thing after being dropped. Unfortunately, I could not find a service guide with any pictures of the inside components, so I had no idea what the insides should look like. I decided to tinker with it since it was doing me no good without photo capability. If I didn't fix it, I was going to have to replace it anyways, so really nothing to lose for me.

This is what I did and maybe it will help you as well. Grab some slim tipped tweezers and a good desk lamp. I took out the screws from the case(you might try an eyeglass repair kit screwdriver or check Dollar Tree--I found and excellent little set of teeny screwdrivers that worked perfectly on these tiny screws. Be warned--mine were in there tighly and I had to put the screwdriver in pliers to put enough pressure to loosen them up. Just be careful you don't strip them.). Ok, once you remove those and set aside someplace safe, remove the battery. Now, very carefully work the front cover (lenscover side) off the body. Work over a table and be very gentle in case you have any loose parts inside. You will NOT want to lose any if possible! In the middle of the circuit board there is a tiny box that may or may not have a little black plastic *switch* inside. When I opened my camera I found: a tiny black switch, a tiny coil of copper wire (spring) and a silver metal bracket looking thing all rolling around. If you have these, then you need to put them back in place in the small box looking thing (it will line up with the back of the lenscover where you see a copper tab). To do that, you need to get the switch and coil together. I found you can do it two ways--one may be easier for you than the other. You can
A: Grab the copper coil by one of the ends sticking out with the tweezers and setting it into the underside of the switch. Use the lamp to examine the black plastic switch and you will notice on one side it has a little groove where the coiled side sits inside. As far as I could tell it doesn't matter which way you put the coil in or where the ends stick out. Then pick up the assembly with the tweezers (by the switch's little tab) and set it gently into the notches at the back of the box. If you examine the box under the light you will see (faintly) the notches where the little nubs sit. Once you get it in the box, the switch should easily be pushed in the down position (not all the way, though, or you will cause the spring to pop the whole thing out!).
B. You can grab the spring with tweezers and set it into the box at the back. Then grab the switch with the tweezers and position it over the spring and into the notches.

Either way, it DOES take some time so be patient. I was dropping the thing all over before I finally got them to work!

Now, with that back in the box, you need to attach the silver metal cover. Examine the cover and see if it is bent in the middle or if the little bent sides are flattened. You can use the tweezers to bend them back into a [ shape. This will fit over the switch and clip onto the box to hold it all in place. Now, once you get the metal bent as it should be, notice the slot opening and align that with the switch. The switch that springs up (not the end the spring is IN) needs to fit right inside that slot. Don't worry--it takes a bit to get it in there. Once it is lined up you will need to work the switch into it and push down. You may need two tweezers to hold both ends down so one doesn't spring up and out..or use a tiny flathead screwdriver to hold one end down. Keep working it until it clips back into place. Once it is fastened you will see only a tiny portion of the switch jutting through. You can test it by running a fingernail (or tweezers) over the switch to push it down and make sure it springs back up.

This part is needed because the lenscover, when opened, pushes the copper plate (found on the back of the lens case you removed) out which makes contact with the switch pushing it down, which in turn causes the camera to come on. All you need to do now is replace the front cover--carefully, lining it up and clicking back into place. Hold it together, add in the battery and try opening the lenscover to see if it works. Hopefully, it does! If not, something else may be wrong. If all is good, screw back in the screws and viola! I wish I could have taken pictures of the process as I know it would have helped me, but this is my only digital so I couldn't. If anyone needs help I can try to draw the parts if needed.

I hope each of you find a solution. These things are pricey and I was near tears when mine wouldn't work. Best wishes!!

SOLDER. I fixed this by removing the 3 small components in the box (spring, plastic piece and steel clip) and putting a blob of solder across the contacts in the middle of the base of the box. A fine soldering iron point and a small amount of solder on the tip is all thats needed. You can test to see if you successfully shorted the contacts by powering up before putting the case back together. As with the conductive pen method, I can now use only the side power button to turn the camera on and off (no big deal) and use the front lens slider cover just to protect the lens from dirt and grease. Anyway, everything works fine and its really quite simple... 6 screws and few minutes to solder it, maybe 20 minutes total.

I just did this. open the camera up by unscrewing all the screws on the side. then on the front side of the camera where the lens cover would be, there is a small spring and black plastic thing. when you open and close the lens when the camera is working properly, it applies pressure to this black plastic and spring.

my solution:
i took this spring and black plastic thing off, then took a small screw driver and touched the small thin pieces of metal behind the black plastic and spring, which caused the camera to turn on and think the lens was open. i then go a conductive ink pen from radio shack, and filled up this area so the metal is always connected to the other metal through the conductive ink. now the camera thinks the lens is always on, but at least it works. i can still turn the camera on and off with the side power button.

My Sony DSC T7 camera lens problem, When I slide the cover of lens, its says that "Lens cover Closed". so I am unable to take picture. Please help me. Thanks Anil

Mr anil there seems to be a problem with the sensor linked to the lens guard. Try to move the lens cover a few times and try to open the cover as much as possible just to initiate the sensor. If this does not solve the problem then you have to show it to a mechanic.

Sony cybershot dsc - t7. the display says ''lens cover closed''

It appears that you have already tried what I'd have suggested as a last resort. Apart from cleaning the contacts and removing the battery for 15 minutes there is not much that can be done.

In my opinion it is better to purchase new camera than to spend so much on this one. Note that sony may also charge you a checking fee if you decide to send the camera in hope for less costly repair than they estimated.

And yes, it would be fruitless to dismantle the camera if you are not qualified for this stuff. There are no user serviceable parts inside and also there are timed mechanical switches which can be difficult to reassemble without a proper schematic.

PS. Please do not use Vodka for cleaning electronic components as it contains small amount of moisture. Use Isopropyl alcohol.

DSC-T7 : Blurred images ?

I don't own a T7,but I have the P150 and S40. All these small Sony digicams have something in common;Sony uses 1/40 as the default flash shutter speed in low light conditions,while other makers use 1/60.You are more likely to get a blurry picture compared to other digicams you have previously used,unless you hold the camera steady (two hands). The other thing about these cameras is their lack of weight, coming in at a mere 134 g/4.7 oz. Light weight means you must hold the camera steady (two hands) or risk camera movement when you press the shutter. Again, the tendency with a small,light weight camera is to hold it with one hand while you take a picture,this leads to blurry pictures. The review for this camera is positive; a "Dave's Pick." - Just remember the flash range is only 5ft / 1.6m.

What causes translucent white circles?

Vijian - I own several digital cameras, including the DSC-55. I have not experienced this problem with my camera. Try two things......adjust to "low" regarding your camera's flash setting, and secondly, put a piece os scotch tape over the flash and see if this helps. Be careful not to cover your light sensor on the front of the camera's housing.
