Thank you very much, I have contacted them, They will help me but since I bought it second hand they will charge me for parts

I have realized I have no motor feedback also, but motors are working, Probably My Mindstorm brick has a problem,

Thank you, I tried all cables now, they are all same,

Am very new at Mindstorms, I just use the try me, data log on NTX and Lego's application for programming NXT in a computer, I have tried the change ports, I could manage to get feedback from every port with touch sensor but, I couldn't get any feedback with my other sensors. What is this I does not understand : An advanced step could be to hook up a logic analyzer and check for i2c messages on the sensor bus but that is not really LEGO

Hello, I have a problem with my NXT 2.0, My colour, supersonic and light sensors are not working however, touch sensors are working, Even there is no light at my sensors. Is there anything for me to solve this problem. Is the problem on my sensors or on brick ?
