Looks like the same type of pics that an IR homebrew takes when you take out the IR filter; they have a pink hue. I'm guessing your camera has a filter because the bear pic is perfect color rendition. The filter must move out of the way when it takes a night picture with the IR flash. I'd guess that the filter is stuck open. The poor flash in the last pic could just be that the flash capacitor charger was in the middle of it's charging cycle and not fully charged.
Check the firmware update, though. That's a good place to start. If not, and it's old enough that Cuddeback won't fix it for you, and you want to dig into the guts of it, then maybe you could find something wrong. It's a jungle inside a camera, but someone designed it, and someone reverse engineered it, and someone else has probably posted the info on the web to start learning what everything in there is. You never know...you might even get lucky enough to fix it, but pray for the firmware update!
