Hopefully someone can solve my problem....
I have a DX3 set comes with a SR300 and HITECH 645MG servo.
I was testing the other day and all in a sudden it doesn't steer anymore.
I disconnect everything and reconnect but i found out that whenever my servo plug is in the STR slot the green LED blink and the blinking stop when i disconnect the servo plug.
i took the servo apart and check all the gear. all of them seems fine to me.
but i found out motor inside the servo doesn't turn
It would turn for a first second or two when i connect the servo to my SR300 and it would stop and give me the blinking LED after

I am looking to buy another servo already but i just want to make sure if the 645mg is completely dead or not

Thank you all for helping
