unfortunately this has happened again, and this time I had the presence of mind to take a picture of it on my cellphone (sorry, not the greatest quality). Again, turning it off and removing the batteries solved the problem and it's working fine afterwards.
anyone know what this is caused by or have had this happen to them too?
Interesting. I've only ever seen that once, similar pattern diff colours, on bootup from cold and a quick (instant reflex really, unplanned) reboot solved it - to my relief. Didn't have to remove batteries.
*VGA monitors will do similar, not sure whether it's the Vsync, Hsync, whatever res/modes switching-circuitry spits the dummy on fire-up so you end up all out of phase. Kinky patterns sometimes, v stripes do get boring after a while though.
Have had the stupid K-x OS display crash twice too, while navigating & changing settings in Menus. It split-froze about half of the screen horizontally and wouldn't scroll out of that state, even on attempted full redraws. But again a warm reboot fixed that too on both occasions, and initial panic wasn't justified, so was obviously a soft error I'd say.
I reckon the K-x with its o/c'ed sensor can get pretty hot under the collar inside (after heavy use), which explains their forced DFS, but surely not cold bootup issues.
Sorry no real help to your issue. Hope it's not too recurring and fatal. Ever got it wet, or moisture, abnormally hot, cold, or rapid temp change environment?
Good luck.
