Is the NXT not starting up *at all* (no startup sound, no USB, no screen), or just the screen is not turning on? I ask because ageing NXTs have historically had a lot of problems with screens ceasing to display anything, though the rest of the controller's functionality is not impaired.

Never mind, it's fixed. Turns out the battery terminal was not properly fitting the new batteries.

Excellent! Glad to know you figured it out. Lego no longer offers replacement NXTs so the only other course of action would be a third-party reseller such as Ebay or BrickLink.

# Lego Mindstorms NXT 2.0 Not turning on

(Asked by: username_0 on 2020-01-02)

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.
