Blue light and servo

Hello, I soaped the bottom of the sled to prevent jerking movements. It was fine until the retract function made the machine fall off the table. A servo motor took the shock and I had to reassemble it with its reduction gearbox. Now the blue light is flashing and this motor no longer reacts to the extension function. What can I do?
When I reverse the RJ45 cables, I have no reaction. I think the motor is stuck.
Maybe I should buy a new motor? Any advice?
There was nothing broken, which proves that the machine is well designed. Even at the engine level, just the gearbox was just a little deformed at the two screws that connect it to the engine.
the only difference i see is the axle sticking out at the top of the motor is slightly recessed.

Edit: Disassembled again, the gearbox was not turning well, by manipulating the gears, I unblocked it. The engine turns again with its gearbox. It is noisy…

If its noisy I would just buy another motor. Sounds like it is running on a wing and a prayer, so better to buy the spare now and be able to swap it out when the gearbox tears itself to bits.

You would probably want to buy another arm and maybe even an encoder too, the threadlocked bolts seem to stay in place pretty well so you might trash those trying to pull the motor off them

The engine itself is intact. I think some dust got into the gears of the gearbox. I looked for the reference written on the engine but I’m not sure. Does anyone have a link, preferably aliexpress? THANKS!
