dear all, I am a newbie on the TM world and just bought my first second used today. Unfortunately, the TM worked 5 min and since that time it stopped. I open the hood and I noted that the led is blinking meaning that the motherboard send info to the motor but the motor just moves 2 inches and stop. it looks like there is a short in my motor because i can see the small electrical arc from the motor. I can post a video if easier but any idea would be greatly appreciated.
