LED panel .

[Aokane]

Hello I am new and need a little advice if possible. 

I bought one of these off Ebay thinking you could just wire up the + and - (see pic) and they'd all light up but no, seems they can all light up individually. 

So I wondering if there is an easy way to wire them up so they all come on with one connection. 

They are four legged super bright white LEDs.

Any help would be awesome! 

Cheers!

I cannot see which connects to what. Can you provide a schematic?

So the green boxes are where the Leds are then its connect along pink and then opposite side light blue lines.

Seems to light up on the diagonal? (Bottom left leg + top right leg - )

It's a bit confusing .

Can you provide a link to the ebay ad?

Your schematic shows strings of 3 LEDs in series and a tiny resistor is also in series.

Your pink and blue lines show that all the strings are in parallel.

Since a white LED is about 3.2V to 3.6V  then the entire bunch of LEDs uses a 12V supply.
