Re: my X700's shutter isn't working when i press the...
There are actually two capacitors, one on the bottom of the camera, the other on top, just beneath the film speed selector. these are both 220uF, 4V electrolytics. they can be successfully replaced with 220V 6.3 volt capacitors (tantalums are best), provided the size is essentially the same. Just make sure you install the capacitors the same way, as incorrect polarity will cause the caps to fail. check out http://www.twid.de/x700/disas.html for detailed instructions.

These use two of the L44 common button battery. The + sides of the battery (flat) goes towards the body ... the bump goes towards the battery holder. Check the contacts on the body and where the threads (-) contact the body. Not voltage, no work. Assuming you have 4 different batteries, can you check the batteries ? One bad one of two will not allow voltage. I have bought new button batteries that were dead right from the package. Strange two cameras are dead. They have electronic shutters. The LED should light up in the viewfinder when the shutter is slightly pressed.
If your shutter curtain doesnt close, it may be out of Sync with the shutter button. My Minolta x700 had this problem. My camera guy fixed it for me with a couple of tinker moves. Contact your nearest camera repair shop (if available) and ask how much it would be to fix the Sync between depressing the shutter button and the curtain. it may just be some grime that has it stuck.
It is nothing to lose to try this:
1. Remove the battery (the charged and good working battery),
2. Switch the power to ON position,
3. Press the shutter button for 5 seconds.
4. Switch the power to OFF position,
5. Insert the battery,
6. Switch the power to ON position,
7. Try to take a picture.
Try pressing the "Menu" button and disable "Active-D Lighting", also try setting the "Autofocus mode" to "Single". When the camera is off, press the shutter release and twist with the zoom know back and forth. Hopefully that fixes it! It worked for my P500 with the same problem.
hiit is not easy to tell what exact problem. It has quite of causes in your case. But I can only tell most common cause that it is sequence unit fail. It could also other like shutter fail, mirror box mech fail, motor fail, control pcb fail, and so on...etc...I recommended you bring to your local service place or Nikon service center which is helpful to you.
Does the shutter button feel like it's contacting twice as you press it in? if not, the spring disk in the switch is split; It has happened to me on other cameras on several occasions. Solution is to replace the switch.
If it works otherwise I would suspect the ribbon cable. They can get loose, or the contacts can get oxidized. I don't know specifically about the c-8080, on some cameras the contacts are tinned, which can oxidize. In that case it's a matter of gently rubbing the contact strip with a paper eraser until the contacts become shiny. Of course, that means disassembling the camera ;)
You've probably retired this camera or don't have it anymore but in case you still have it, I hope this helps a bit.
The Pentax is a easy fix, maybe.. If you feel comfortable removing the bottom cover, then remove the 3 cross point screws. The battery, if installed will be loose. Looking at the bottom section of the camera, locate the tripod socket. On on side is the battery compartment, the other an L shaped lever. Under the L shaped lever is a brass plate with a slot in it. In that slot is another lever that has a spring going through the end eyelet. Move that lever toward the front of the camera until it latches on the L shaped lever above. Then try the release.
The first thing to try on the X700 is fresh batteries. Clean the battery cap and contacts with a pencil eraser.
Are the batteries good ,is the battery cap and contacts clean? Can you fire the shutter? Move select off auto and try to release the shutter. If the shutter fired off auto and will not fire on auto with good batteries. Either the shutter or flex circuit must be replaced. There are no new parts avail. for the X700.
One other item for the X700. check to see if the shutter fully traveled on the last shot.
I think the timing of the shutter winding gears has slipped a tooth or two. look at the picture in this image:
Near the motor drive coupler at the bottom you will see a blue and a white gear. Look closely at the blue gear and you will see a line on the top of it. That line needs to be pointed at the center of the white gear when the camera has been released and ready to be advanced again.
If you wish to proceed, I will tell you how to re-time the gears.
This is weird, usually shutter delays are caused because camera is trying to focus first, it really shouldn't happen after pre-focus. do you have a manual focus mode? if you do, try it and see if it works. if you dont, I would still suspect it some kind of focusing problem, but unfortunalty i have no idea how you can fix it yourself.
