To correct the issue, make sure that the sash is aligned in the frame's opening and remove it. If the sash has been attached to the hinge arm, take it off the hinge and replace it. (Photo 2).

A weight in a sash that has fallen out of the cavity is difficult to recover and you'll need to locate a new one that fits correctly. You will also require a new piece string, a length sashcord and a few sashpulleys to secure the new weights to the cord.
Older wood windows are joined with mortise and tenon joints. The wood pegs that keep the components together can be removed with pin punches and hammers. The majority of them have an enormous diameter on one side and a smaller one on the other side, so it is important to remove the small-diameter sides first. Sashes made later in the century used glue instead of pegs. They can be separated by cutting through the glue line with a knife, then tapping the mortised area loose using mallets.
After the sash is released, you can remove sash stops and gain access to the pockets for weights. Usually, this is done through a hole near the bottom of each jamb. This hole is covered with the wooden panel which can be removed to reveal the inner workings.
