I recently was having issues with a sticky button, and silicon grease wasn't helping at all. I decided to get a replacement button pad, since that seemed to be the most likely problem. After installing the new pad, the good news is that the button is no longer sticking. The bad news is now the shoulder buttons don't work!
Right after I turn it on, it cycles through the top icons (as if I were holding down the Left button), and then it stops somewhere. Pressing on the Left and Right buttons does nothing. Now, I did take it apart and made sure that the connectors were seated securely and all. Unfortunately, it looks like I did break one of the red cables off, but that wouldn't explain why both buttons are broken, right?
So, my next question is: If I can't fix the shoulder buttons, should I get a replacement Zero? Now, I really, really miss my Zero, and I would like nothing better than to be able to play on it again... However, I don't want to buy a replacement for $150 and then have the buttons start sticking in 6 or 8 months like this one did.
Has the quality control gotten appreciably better in the last year or two?
