Looking for help with a repair 
to be able to advise a capacitor rating.

I have a 13.5V 5W 21 led strip.
Each LED 70ma 2.2  forward voltage.
Apart from that 1pc SOD 2pcs 1k resisitor and 47r x 21

Any genius able to work out suitable uF for this head scratcher 
Tried 16V 47uf and it shorted a LED at end of circuit. 
I feel is breaking down.
