I have a CHIP and the back legs are down and refuse to move. I took the Main PC board out and found a cracked and burnt MOSFET next to the plug for the rear Motor legs. It is a SMD (surface Mounted device) and will be difficult to replace since it is so small. I feel that all the (REPLACE GEAR BOX) solutions are BAD ADVICE.
