Shutter curtain dont reset mirror in certain speeds
It started when choosing 1/125th speed, the curtain wouldnt go all its way to reset the mirror, i would have to either slam the camera or i could touch the curtain (not a option when film is loaded) to fully reset the mirror. Its gotten worse, now 1/60th and 1/250th speed show the same problem and slamming the camera wont help anymore, so i if take a pictuer at those speeds, i will probably have to take the next one blindly at any other speed to reset the mirror.
would it be expensive to fix this? could i do it myself? things are expensive down here and this camera has been serviced before...I wouldnt like to give up on this camera, its been with me for a while.

Re: Shutter curtain dont reset mirror in certain speeds
your K1000 needs a clean, lube and adjust. ( CLA ) the shutter must be repaired and calibrated. not a hard job, but a special calibration instrument must be used to calibrate all shutter speeds.
slamming the camera just makes things worse, you could brake the meter. take or send your K1000 to a camera repair shop and get an estimate for a CLA.
there are no new parts available, so if the camera requires parts the shop should state good used parts only.

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.
Your second curtain is not releasing the mirror to come down. This happens with weak 2nd shutter curtain tension. If the wind lever is stuck and the mirror does not come down then the mirror tension spring came off.
Try shooting on slower speeds such as 1/30 sec and less and see if you can see some images. If all the pictures are black on 1/125 and faster speeds, you will need to have the shutter curtains adjusted.
it sounds like its set up for a very slow shutter speed
ie:30sec's? and your getting triger happy trying to rush it to take the photo and get it over with, check when film speed its set on and what shutter speed its set to,and stop poking the mirror about or its going to cost you big time bucks getting it fixed,
Sounds like the shutter needs repair. Either the opening curtain is sticking or the closing curtain is not holding long enough. Another problem might be the camera's sync speed might be lower than 1/125 of a second. Many cameras use 1/60th or 1/90th of a second as their flash sync speed.
If its black when you look thru the viewfinder its likely because the mirror is stuck in the up position. It will often do that if the batteries are exhausted. Try replacing the batteries.
The mirror might release back down if you turn the shutter speed dial to M90. This is a manual release of 1/90 second for when you need the shot but don't have any power.
When you look in the lens opening and adjust the aperture dial, you are seeing the aperture open and close. Not the shutter. You need to open the back of the camera (without film) and take a photo to see the shutter curtains open and close.
You should have a read thru the manual to become familiar with the camera and its operation:
Sounds like you are having some photo taking issues. There is a rule of thumb for shooting, It is the focal length must be equal to or less than the shutter speed. Example. 100 mm lens must have 1/100 of a second or faster when hand holding a camera. If your shots are too blurry or out of focus, try using faster film speed, ie. 400 asa or 800 or 1600, try using a flash if you are going to be at 1/60 a second. The faster the film you use, allows you to have a faster shutter speed. Another option is to use a tripod, and then your shutter speed is irrelevant.
The N80 has a vertical travel focal plane shutter. This is essentially two curtains that travel across the film plane. At lower shutter speeds, one curtain opens up the shurter, you wait, then the next one travels across, stopping the exposure. At faster speeds, though, they both move together, leaving a small gap between them to let light through.
If the first shutter curtain isn't always making it all the way to the top, this could give you just what you're seeing -- a black band across the top of the photo. One blank negative may well indicate that your shutter failed completely on that shot.
This is something best handled by a camera repair shop. It could possibly just be some dirt in the shutter mechanism, which would be fixed by a good CLA (clean, lube, adjust) ... that's no a bad idea if it's an older camera anyway. However, it could be more than that. It won't be clear which without getting down into the camera itself.
