right side solid green light but no light on left

hey i need some help with my original (clear) xbox, having a slight problem, so when i got it (given to me free as wanted to go back to childhood times) there was a problem with disc tray opening slighty but not all the way and managed to fix it, when disc drive was stuck it was flashing red on left side of eject button. Now that i fixed it only the the right side i have a solid green light but no light on left side, and my controller wont work, i opened up controller and wires look fine to me but not sure of it is controller or ports, hope someone could give me some advice
