Well written. Impressive. Maybe one of you smart people can save me time and tell me what the + button only doesn't work but when I disassembled it, thinking prob would be obvi and/or button assembly would he broke.
But everything looks fine. Once I cleaned it u a little, using all electronics approved products and methods, it looks great. Including the entire assembly for all the buttons. When I compared them, there is no difference between broken buttons and the working ones.
My son is autistic and actually ddressed cuz this thing is broken. I figure I gotta start by ordering a new +button and replacing it, so I will do that by wend of today. But if a NY chance a replacement button isn't the fix needed, I will do whatever is needed.
I'm just worried I'm going to order, wait, then repair, only to find out that didn't fix it And I'd be ba k at square one, with no leads as to what is the real problem.
Any advice from a tech savvy genius would be awesome.
