Lego Mindstorms NXT 2.0 brick is not working Recently, I tried to get my old NXT 2.0 brick fixed.
Everything seemed to point to the clicking brick problem, but it turns out not to be the only thing, the brick was also getting hot. After disassembling it, I found that the "q27" transistor was burning up.  

There is "11 2x" written on the part, but it didn't point me to anything on the internet and I couldn't find any schematic for NXT 2.0 on the web. Any ideas how to identify the part?  

Or maybe anyone saw the schematic for NXT 2.0?
Would writing an email to Lego give me anything?
The electrial schematic for the NXT is available in the LEGO &quot;NXT Hardware Developer Kit&quot;. This can be found on the official LEGO MINDSTORMS download page near the bottom of the page in the Advanced Users – Developer Kits section.
