I have a Lego Mindstorms NXT 2.0, which worked well for a couple of years. However, after the last few weeks, it seems to not boot up. I took it apart, and noticed it seems to have a different internal design than the other ones. After screwing around with it for a bit, it unexpectedly boot up.
I thought the plastic part holding the ribbon cable in place was putting too much pressure on the cable, causing malfunction. After I reassembled it with less pressure on the screen mount, and sealed the unit back up, it seems to be dead, again.
Any help? I prefer not to solder.
