I recently purchased the Graveyard Reaper. Everything works except for the LED lights in the eyes of the coffin guy and coffin LEDs. Anyone experience this problem? The Reaper works fine and the door opens fine just no lights in the coffin.

It generally depends on how the LED's are wired. They could be in sequence or parallel, which just means that either one of the positive LED connections and one of the negative are connected directly, then the remaining positive and negative are connected to the power source. Or the LEDs are each connected to the power source directly.

If they are in sequence(which is unlikely as its uncommon to do this), then if any one of the LEDs was broken then neither would work(similar to a string of Christmas lights). To fix this setup you would need to test the individual LEDs with a battery with a lead rig consisting of wires and a resistor to power each LED directly without damaging it with too much power. Once you identify the non functional one, you remove it from the prop and rewire a new one in its place in the same way the old one was using a soldering iron. Again this is an unlikely configuration.

If they are in parallel(the more likely) then for both of them to not work it means one of the main lead connections or wires internally are broken(either positive or negative). If the failure is not an obvious broken connection to the main board or the LED terminal then to test which wire is broken you need a new wire of similar length and strip the ends. Find the wires in the prop that lead to the LEDs and take your new wire and use it to make a new connection from the circuit board to the LED assembly. Touch the wire from the board positive connection to the positive connection on the LED assembly. If no change, then touch the wire from negative to negative. If the LEDs light then you found the bad wire. De-solder the old wire out and re-solder the new one in.

Be careful not to overheat parts while your changing out the wires. Optionally if you really don't want to solder, clip the old wire you identified out with wire cutters leaving a good amount of lead on each side. strip the casing off and strip casing off your new wire. twist the ends on each side well to make connections and use electrical tape to bind and protect. This won't do as well as soldering as eventually the electrical tape will loosen from weather but it'll do.

Otherwise if there is some kind of warranty then return the prop and get a new one. If you go this route do so before you attempt to work on it as home repair always invalidates a warranty.
