Pentax Lens SMC F 35-80 will not focus

I found the lens binding up for both zoom and focus. By working the lens zoom and focus back and forth it freed it back up. But now, it will not focus an longer distances. Turned to infinity focus it is only good for 10 - 15 feet with anything beyond that out of focus. Tried both MF and AF with same result.
It is an inexpensive lens and sending it out for repair probably does not make sense.
Any ideas on attempting a home-repair before throwing it away???

Sounds like it's broken to me- if you have nothing to lose, you could try opening up and seeing if anything is broken inside, but it might not be the effort

Throw it away or open it up to learn something about the internals.

Somebody today offered me 2 AF film bodies, 2 similar standard zooms (not quite sure which models and a FAJ 75-300 for roughly US$55 (converted). I said no, but might still make up my mind

Apparently, the front lens element had popped out a bit. Works fine again.
