So, I finally worked up the nerve to open my Zero, to figure out why the 'A' button wouldn't spring back up, and I found the answer.  The rubber membrane under the button will not spring back normally (shown in attachment).  Basically, three of the four button membranes spring back instantly no matter what you do with them, while the fourth, the one under the 'A' button, sticks frequently.  Eventually, with the membrane out of the Zero, it springs back, but obviously with the button and case holding things together, that does not always happen inside the Zero. 

I know people on here have replaced buttons and such, has anyone had any luck replacing the membrane?  I have no expertise in locating parts....and would like to at least try to repair my Zero rather than just replace it, especially since I have it open with minimal damage (I pulled one of the wires to the L button, but I can fix it). 

Any ideas of getting a replacement part?  Or a part that's close enough that I don't have to do a whole lot to modify it?  I'll measure it up and have a schematic when I return to work on Tuesday (we have digital calipers there) for comparison's sake. 

Thanks in advance -- been jonesing for my old game systems, and have only been able to play them at home lately.....

I hear the DSLite membrane is potentially compatible

I have the same issue... The rubber membrane for my A button is totally trashed. I'm hoping future units will use a higher quality one.

this thread is really old but i just opened my unit due to this same issue and my membrane was completely broken. i cut up an old remote from a tv and put the membrane buttons in place using the existing membrane. it works fine now but firmer to press. which isn't entirely bad.

Great necropost.
That website is Japanese by the way. Not very useful.
