I have a remote control for a Sharper Image drone. The unit does not power up. The battery power is correct so I open the unit and see that the first component on the circuit board appears to be blown, see attach photo.
After some research I have come to the conclusion that the blown component is a surface mounted diode. The controller runs on 9 volt DC. I suspect the previous owner installed the batteries incorrectly and blew the diode.
The component is very small measuring 1/16th X 3/32nd with tabs at each end. It desoldered from the circuit very easily. What would be the replacement for this component? Where would I get one?
