if my strap rivet breaks, the last thing i would do is send it in for repair...mistake #1.
that's just my opinion, and has nothing to do with panasonic reaffirming their firmware on my cam. just find other means of supporting your camera...seriously....i have never trusted a strap (or the hardware by which is hangs) ever...my hands work better. honestly, i didn't know people still send their cameras in for such a repair....seems as antiquated as bringing shoes to a cobbler to be re-soled. who does THAT?
Except that it's not just a matter of choosing to live with camera that has a missing strap lug.
The lugs fall out because the nut on the shank falls off inside the camera. That nut can then cause major damage by shorting out the PCB's.
Note that the OP stated that his strap lug fell off - and *then* the LCD screen stopped working.
Presumably, it stopped working because the offending nut had shorted something out in the camera.
He, actually, was lucky - in that he was still able to re-load original f/w prior to sending it back to Panasonic (I'm assuming it was a warranty claim)
If the strap lug falls off and the nut shorts something out to the extent that the camera is 'dead' , you have a problem if hacked f/w is on it and you want warranty work.
