I tried to install the gecko g540 today which had been on service and there is still problem with it. When I turned the current on, it came a litle cracking noise and there were not any lights on it. No green or no red light, but a litle red light inside where some resistors are attached to the motherboard. I had nothing connected to it, neither motors or seial cable. When I removed all the drivers and tried to turn on the motherboard again, only the red led is lighting on the front but also the small red light as I mentioned above.
What may be wrong?
