Well, the display finally died. But the adventures of Badass Mountaineer Camera go on! Today I finally got around to swapping out the LCD panel with the one from my other A590 (see below). When I took the case off all kinds of things that had broken off the motherboard and the inside of the case fell out--resistors, caps, plastic, chunks of LCD, etc. It was quite a humorous pile of components that the camera has been functioning without.
This was actually my second A590. I bought one new in '08 for $100 and after a year and a half of 14ers it started having sensor issues (I think--photos were plagued by random blurring, zoom came out all blurry). Canon had stopped making them by then, and as they no longer carried a PowerShot with full manual control short of the G11 ($$$), new A590's were selling for upwards of $300. I bought a used one on ebay for $100. That's the one that fell off Mt. Adams.
Anyway, Badass Mountaineer Camera now has an intact case and shiny new LCD panel donated by Bad Sensor Camera, which unfortunately did not survive the operation. BMC is recovering (actually it's working great). I wonder what all those parts that broke off the MB were for.. meh.
