I need to find a repair manual that shows me how to open and disassemble and repair the wind up mechanism

You need to have the door disassembled and the window lift mechanism checked. Sounds like the actuator arm has come off, or the motor is dead/dying. (You didn't say whether the motor makes noise when you try to operate the window.) If you're a DIYer, there are any number of videos on YouTube that will show you how to do the diagnosis.

IT DEPENDS ON WHAT IS THE PROBLEM.U MUST FIND THE PROBLEM TO DETERMINE THE TIME TO REPAIR NEEDED..

The "shoe thing" people were referring to is the camera's hot-show. This is where powered attachments (usually a flash) is mounted on the camera. The metal plate on top of the camera is the hot-shoe. It should look something like this: http://a.img-dpreview.com/reviews/CanonEOS450D/images/hotshoe.jpg
However, it is likely not an issue with the actual hot-shoe. It is most likely an issue of your camera's mechanical mechanism for releasing the flash being out of alignment. Try wiggling the "manual release" button for the flash to the left and right and see if it will catch on the mechanism. Then try pushing the button to see if the flash pops up.
You can try gently opening the flash manually with your finger, sometimes it is simply a buildup of dirt and grim blocking the mechanism and once this is cleared, it should work normally.
If you get the flash to pop up but it still will not fire, try the below method: Sometimes the camera can be confused into thinking that an external flash is attached to the body, thus making it ignore the internal flash. This can be resolved by moving the microswitch under the rails of your hot-shoe into the up position (it should be down when you see it) using a toothpick. You can access this after opening the flash up manual, as described in the previous paragraph. Here is an image showing where to find the switch: http://www.business-improvement.org/fixes/canon_350d_rebelXT_flash.htm
Thank you for choosing FixYa.com! have a great day!

I suspect the problem you have is a stretched drive belt (from the power motor to the slide change mechanism). The good news is there are still parts available from: www.micro-tools.com The problem is the replacement of this belt is a involved disassembly - at the very least you would need great mechanical aptitude and (most important) a service manual. I would recommend locating a factory-trained service dealer to make this repair for you.
Good Luck !

Probably the spring broke which returns the latching mechanism to its "open" position. Pull the door handle and hold it. Take a screwdriver and flip the latch (catch) in the door to the open position. Now, you should be able to close the door 1 time, and it should latch. You need to replace the latch mechanism as soon as possible. You can get a used one from a junk yard. Some on-line parts stores also have free on-line repair manuals which show how to disassemble the door and replace the latch. It is not a difficult job. Anyone with some basic tools should be able to handle it.

When you say "wave wind" do you mean you're waving it around to wind it with the self-winding mechanism? If so, that will only keep it running briefly as you're experiencing. Manually wind the crown about 40 turns clockwise to "fill the tank" and wearing it daily will keep it topped off. Anytime you don't wear it for a day, manually wind it again. As for the cleaning, the inside of the watch doesn't get real dirty but over time the lubricants wear out and thicken which makes the watch run slowly or not as long as it has to work harder to move the gears through the thickened lubricant. A watchmaker can disassemble and clean the old lube out with solvents and then reassemble the watch with fresh lubricants.

Disassemble your home sewing machine for routine maintenance Many sewing machine repairs can be made at home, and most repairs can be completely avoided through routine sewing machine maintenance. This tutorial shows you how to carefully disassemble your machine to give it a round of maintenance. You will need a screwdriver - make sure not to lose any of the screws!

That camera has several rubber bumpers and gaskets in the mirror mechanism that have a tendency to turn into sticky gooey sludge causing the levers in the shutter and mirror mechanisms to get sluggish.

The latch that tells it to stop winding is not dropping into proper position when you wind the camera. Try holding the film advance lever all the way to the front when winding it to allow the latch to drop into place before letting the lever to return.

The only permanent solution is to completely disassemble the camera to clean out the old goop and replace them with newer neoprene fittings. My suggestion would be to find a replacement body since the repair is probably going to cost between $80 to $90 and you can probably find a good used body for less than that.

It sounds like the drive belts on the deck have broken (not allowing playing, FF or REW) and/or the tape got "eaten" meaning the tape itself has wound itself around the rollers and cannot free itself. I strongly doubt this is an electrical issue. Definately sounds mechanical.

As far as the door not opening, there's usually a hook that holds the door closed. If the unit is mostly disassembled, look near one of the sides of the door for a metal hook. It's normally spring loaded and can be moved manually. That should free the door. If your tape was eaten, it might take some gentle persuasion to unwrap it from the rollers.

Good luck.

Hi: You may want to try changing the aperature setting,or removing the lens,then re-installing the lens. Good luck.
