You could also check to see if the flash is set to use a Yongnuo radio trigger mode, which you could undo, set the flash to M, and test.
Yes have tried the X mode of K-5, though I always shoot in M, but this was out of frustration that I tried the X mode.
And also tried all the four modes modes on the flash just hoping some mode would raise its hand and say 'There! It works now', but no luck!
Can it be that its because its a Pentax camera? I was going through a small booklet that Cactus provides with various diagrams of camera, flash, modifier setups used by people and taken lovely photos using the V4/5's. All the photos and diagrams had cameras for Nikon, Canon, Sony etc, but not a Pentax! One diagram also had a Yongnuo used with a Nikon setup.

Just posting an update here.
I connected one of the two cords that you get with the V5's to the YN560II, put the V5 on RX. Then put the other V5 on the K-5 hotshoe as a TX, checked the channels to be the same, and pressed the camera button, The flash did not work!
Then I pressed the testing button on the V5 which sat on the camera, and it triggered the flash. But no photo because the camera was not triggered. So in that way the V5's and the YN560II works together, but not wirelessly.
