I have a few dead Align DS510 servos. I don't know what happened to them but they don't power up. These servos came with the heli I bought as spares. I wonder if these got damaged in BEC or ESC failure. Is there any way to test which component on the board is fried?

Best thing to do is open it up and look for something burnt. I fixed a DS620 that had a blown diode due to a failed esc. Post a detailed pic and I can try to help you.

DS510 photo w/ bottom cover off
Here is the picture of the DS510 with the bottom cover off.

Which one is the diode?

Also I cannot take the board off but it looks like there is some kind of scorching/burn marks the other side of the board near the cable where PCB is marked as 12 and 13 with the soldering pad. Is there any way to get the board/motor off from the casing?

Okay. Figured out how to remove the board/motor/potentiometer.

It looks like there is a component that has been completely burnt.

Well since I dont have a DS510 to look at I cant say for sure but that is the same location of the smt diode I replaced that failed on my DS620. The board on yours looks bad. Is there enough trace left to solder a new one in place? try cleaning it with some goof off or other solvent cleaner. Then desolder the burnt component. I would solder in a high current smt diode with the indicator line towards the wires and test it by applying power to the servo only. If nothing smokes hook it up to an old rx and see if its fully working. If you have an old bad pc video card you can locate some high current smt diodes.

Thanks.

I will go through my junk electronics to see if I can find a similar sized diode. Do you know what rating I should be looking for, in case I need to purchase some diodes?

I will look into it. I will tear one apart tonight and see if i can get you a value to use. My only worry is if it a zener diode or just a standard rectifier.

After looking at my servo it was not a diode. It was a tantalum capacitor (100uF x 10v (type C))

Here is a link...

I think the part that burnt out on my DS510 is different.... It has three small legs on one side and one soldering point on the other side.

Like I say I dont have a DS510 here to take a look. Maybe you could post a really close up photo of it?

It looks like a Low Drop out voltage regulator(from Google searching for similar shaped surface mount package). Three small legs on one side. One big ground tab on the other side of the chip.
