I knew that you've update the kernel. But I cannot find anywhere where you
mention the version of your previous kernel.
If you are interested in getting this issue fixed you need to supply more
precise information.
1. We need to know under what circumstances the condition occurs: In the 
   original description you say: 'It seems when the monitor is powered down 
   ...':  'It seems...' makes it pure speculation. Did you ever try to verify 
   it? Can you verify that this happens right after waking up the monitor from
   standby?
2. You claimed you could not see the issue with 3.16.7-29-desktop on one day 
   but you did on the same kernel two days before. This is at least how I read
   comment #8. This doesn't help us much. 
   Was there any kernel before where this issue didn't occur? Did you really 
   verify this? To verify this, you'd have to do 1.

Currently there is too much speculation here. We don't even know if this is a
regression. If there was a kernel version where it worked (and you verified
that it really did - under the same circumstances as the kernel that showed the
issue) we had some marker to go by.

Hardware to replace? How about boo#964429? This monitor looks different...

I'd suggest to test a Leap 42.1 kernel on your 13.2 system. On some kernel
versions the Intel driver played some games with the power wells. It is not
unlikely, that the issues you are seeing are related to this as well. 

As long as you don't need an NVIDIA proprietary driver on this box the Leap
42.1 kernel should be just fine for you.
