Hello. I am new to this forum but was hoping to get some answers from people who really know. I have a 48sx that has stopped working and I strongly suspect it is the "on" button that doesn't work anymore. It started to work only intermittently before it started not responding at all and now I can't turn the little critter on at all anymore. I have tried to pry the unit open, but it is not easy and I am afraid of damaging something. Can I get it into it somehow and is it possible to fix troublesome keys (if that is what it is)? I love this one, and I hate the 33s that I bought as a temporary replacement which has turned into a permanent replacement. Thanks.

with your right-thumb, press on the bezel just above the [D] Key while pressing the on button. If that solves it, you can fix it temporarily by placing a rubber band on the bezel.. not worth fixing if you can pick up a used one fairly cheaply. Edited: 23 Nov 2007, 2:00 p.m.

You'll want to press above the [B] key, not the [D]. If it works, it should be repairable. SX's are the toughest of the lot to open without damage but if it's dead, what's to loose?

Thanks for your replies. I just found Han's repair guide and I am picking it apart right now. It does indeed work if I depress the area above the B button below the LCD. So it should be repairable from what I understand. But whether it is worth it is a different matter. But like you said, since it is dead right now anyway, what's to lose? Maybe I will end up finding a used one, or get a new 35s. Thanks again!

This may be a bit late, but if you are fixing the keys, you may want to also look at: There are more relevant photos there as far as repairs go. |
