After I take 3 pictures, the camera no longer takes pictures or advances the film, and the film counter is blinking "FILM 3", I'm using black and white 35mm film with and ISO of 400, I've taken many pictures with color film and it has worked perfectly. This is the second time this happened with black and white film.

There are a couple of possibilities that I can think of:

First, film must be loaded into the camera for the picture counter to increment.

Second, if you've loaded film, but the counter still does not change, it is possible the film is not advancing (the film release button/knob/lever that you use to rewind the film may be activated) or the film has slipped off the sprockets on the take-up spool.

If you can stand to lose the photos you may have already taken, just open the back of the camera and make sure the film is advancing when you take a photo.

If you can't possibly lose the photos, rewind the film and take the film to be developed. Try to find a local developer that only charges for the photos that "came out"... This can save a lot of money if only a few frames develop properly (or if none come out!)

It's broken. The K1000 will automatically advance the counter to the end of your roll. Removing the film and closing the back should reset it. If it's not doing that, it's broken.

if the film drive cogs are all ok then its the film advance drive gears on the motor drive striped or slipping,,you could test this by opening the camera and genteelly holding the film advance cogs with your finger and pressing the shutter if the film advance cogs stop turning then the drive gears are slipping or striped? this could be caused by the after load censer in the camera not censing the end of film roll and trying to get another frame out of it? like it read a 24ex as a 36ex but the censor faled to stop the motor drive winding on and that striped the gears

The film counter moves without the film inside the camera.
You will need to replace the film counter assembly.

The frame counter will read at least the number of frames the film should have. If the camera will no longer 'fire', the film has probably come to an end.
Rewind the film and take it out normally. You'll notice if the film is no completely exposed since the rewind time is relatevily short.
Anyway, it's better to have a few pictures than no pictures at all.

The film is either at the end or stuck. The shutter will not release unless the film advance lever has gone all the way and back.
Make a note of the frame counter. Rewind the film and remove it from the camera (When you feel the film to come loose from the receiving spool, stop rewinding to prevent the end of the film to disappear inside the can. This way you can reload it if it was stuck in the middle.) If the film was completely exposed, take it to be developed.
With the empty camera, try to advance the lever and release the shutter. If this works, the problem was the film and not the camera. Everything is fine. If the problem persists, take it to be repaired.
If the film was stuck in the middle, load it again into the camera. With the lense cap on (preferably in a dark room or similar) 'shoot' as many 'empty' frames as you had on the counter plus two more. Finish the film and develop the pictures.
If the film stucks again at the same place, rewind it and develop normally. It was a bad film.
Hope this helped you to solve the problem.

You may be out of film. If you used too much leader to load the film, the counter would not know to keep up so you would be off a bit. On the rewind side, check to see if there is any slack in the film, If you can turn the rewind 2 or 3 turns then it is not loading error but mechanical problems.

Do you have film in the camera? If so, is it an old film or you have just loaded it?
If it's an old film, could it be at the end of the roll - to check this, 'lightly' turn the rewind lever backwards and forwards. As the camera is pointing away from you, turning the rewind knob clockwise will normally rewind the film (don't press the rewind button in, we don't actually want to rewind the film yet), turning the knob clockwise should be tight and a firm stop, if the film is at the end, you will feel the same tight firm stop if you turn it counter-clockwise. Don't turn the rewind knob backwards (counter-clockwise) too hard, you'll unscrew it and it may fall apart. If turning it backwards rolls freely in a full circle, then you have film left.
Another option is that, since it's been so long since you used it, the loading of the film may have gone amis and sometimes the cassette will flip backwards, jamming the film in place so it wont advance - if you have loaded the film and not taken any pics or have not been able to advance it at all, it should be safe to open the back as the film will be in it's original loading position, if you have left the film in it from some time and don't know what stage it's up to it may be best to take it to a camera store where they will have a "Black Bag" to put the camera in and manually open and unload the film. Make sure you get an experienced person - some pimply-face teen that's never used a film camera can easily put their fingers through the shutter while it's in the black bag - I've seen it plenty of times.
OK, that's enough to get started, did this work or do we need to try more options?

**.The best way to acknowledge contribution is to rate it's relevance.**

Unlike other cameras that start at frame #1 after loading and count up as the film is used, the N55 advance the film to the last frame during the loading process. When loading is complete, the frame counter stops at the number of available frames on the roll (usually 24 or 36) and counts down as photos are taken. I know it sounds backwards but it actually makes a lot of sense to engineer it this way. After the last photo is taken (displays 1 on the counter), the camera automatically winds the end of the film into the cassette and the counter shows a blinking E. I am assuming that that is what is being displayed and not a blinking F. it it is an F, perhaps there is a problem with the LCD display? If so, it probably isn't worth having it repaired.

Did you try pushing the shutter button? It may already be wound. Otherwise, try pushing the rewind button in and holding it while you wind the lever. Now, it MAY be that your at the end of the roll-what does your counter say?
