I know at least one of the camera's was working fine untill a couple of days ago. The other, well I'm not sure. I'm curious if this is just bad luck or maybe it's a design flaw like the the way the speaker is mounted in the XT894 (same speaker as XT897, had to swap one). I'm waiting for a new digitizer to replace. I'll have a look at that one to see if there's any wear & tear to be found. I hope it's just a bad connection or something. If I remember correctly, this camera uses a ribbon flat cable. So hopefully it's as easy as cleaning and correctly reconnecting it.
I just really, r e a l l y, hate disassembling the XT897 front housing
