We will see about that this winter. I've experienced the multi-colored lines a few times as well. It seems to have something to do with something covering the lens such as putting the thermal with cap open in a pocket or against my clothes, and then it happens. It hasn't happened for awhile so maybe it got fixed in a firmware update. You are right pulling the battery is the only thing that works to get it working again.
A sticky shutter as mentioned earlier in another thread is another common Pulsar Helion situation which is fixed by a quick NUC. Even with these two items that happen once in awhile, I really, really like my Helion.
