Originally posted by Tas I've noticed on a number of occassions that live view seems to be working fine, but then if it's been off and I go to turn it on again I press the live view button and all I get is a black screen with specular grain suggesting the LV is working but the view is obstructed. I will have to check the next time this occurs as to whether there is the noise associated with mirror lock up. I don't recall if there was the MUP noise but will update the thread once I've confirmed the situation.
To get things going again usually I just press the live view button again to turn LV off then press it a third time to turn it back on and it will work. Sometimes I've had to do this process more than once to get live view working again meaning pressing the same button five times to get LV to work.
I thought it might have been a one off initially, however it occured nearly half a dozen times this morning. This represents an increase over the previous occurrences.
Upon reflecting on my experiences so far, I do recall one image where it appeared the shutter curtain failed to work correctly with most of the image black with just a line at the top. I don't recall the circumstances of this issue but it has not repeated itself. It may have also been me, and as this is not related to the mirror it's just added to identify it ocurred (this being a once off I will ignore it but will update the thread if it occurs again).
Has anyone else had a similar experience when pressing the LV button?
Oh, if this is an issue, so be it, the camera is brilliant to use and produces wonderfully detailed images. No regrets on my purchase.

Above is my comment on the previous page where the live view wasn't showing sometimes and I indicated I'd provide an update.
So, on page 60 of the instructions there is a caution that states:
" *Mirror Lock-up Shooting cannot be selected when shooting with Live View."
Normally I select MUP when I am using a tripod and don't use LV until I'm actually composing so not being able to select MUP when using LV is not an issue. However, I had the black screen appear whilst shooting this morning and typically I had been using LV & MUP without any problems before hand. As I'd noticed the MUP icon in the drive menu was greyed out it made me wonder whether this might be related. It was after this I actually read that page of the instructions.
Anyhoo, so I turned off MUP to use LV and found the black screen in LV did not reoccur. I used MUP again, but would toggle it on and off and found I did not get the black screen again whilst using LV. Note too that I wasn't sure whether the mirror movement noise was occuring prior to the black screen in LV. For the one instance of it occurring this morning there was a definite mirror lock up sound when pressing the LV button.
As I've come from a K5, and the K3 did have a number of operating systems changes it may just be my lack of familiarity with the system. Can anyone comment on the LV/MUP arrangement for K3 please?
I'll keep taking notes of when/if the black screen continues or whether the relationship between LV and MUP as described above was the 'issue' I experienced.
