As an update on this (and an FYI for K-S2 users):
The camera went in for warranty repair in the UK, and they stated that they couldn't find any fault and sent it back. It worked for me for all of an hour before re-developing the fault, and nothing I tried could get it to work.
I took videos of the issue occurring and sent these off to Johnsons Photopia (the UK warranty repair company). They again couldn't replicate the fault, so contacted Pentax Europe to ask if anyone had ever come across this before - and they hadn't.
In frustration, they replaced the autofocus module and main PCB and sent it back. Still working 4 days later. Seems like it was a randomly occurring intermittent fault (probably with the autofocus module), which only occurred in my presence :)

Indeed - should have mentioned this - turning it off and on again was tried first, followed by a 30 min period without a battery

Hi all! Long time lurker, first time poster.
Went out for a walk this morning and PDAF has completely packed in, it seems. Live view focusing works fine, but when viewing through the viewfinder, the following happens:
With focus assist light on:- The central AF point lights red
- The camera focuses the lens from wherever it is to infinity
- It then bumps back to about the 3m mark on my 50-200mm; with a 50mm prime on it bumps back a tiny way
- The focus-confirmation hexagon starts flashing along with the flash-needed notification on the left of the viewfinder
- No AF points light
With focus assist light off:- The central AF point lights red
- The camera focuses the lens from wherever it is to infinity
- The camera focuses the lens from infinity to MFD
- It then bumps back to about the 3m mark on my 50-200mm; with a 50mm prime on it bumps back to near infinity
- The focus-confirmation hexagon starts flashing along with the flash-needed notification on the left of the viewfinder
- No AF points light
I get the same behaviour with SDM lenses.
After trying this, if I flip to live view, it hunts for a while, but then starts functioning perfectly. Unfortunately, live view is pretty inadequate for my needs!
I've tried air-blow the PDAF sensor area, factory reset + firmware update, four different lenses, and still have no idea.
The camera was a Christmas gift from a relative who's no longer with us and I've not been able to locate a receipt, so I'm a bit stuck for a shop to take it back to - consequently, any ideas before I try approaching Pentax UK (and inevitably get told where to go) appreciated!
