OP

Quoted from Fred558:

I added a blue led backlighting.

I was also installing all the leds on the playfield, but I noticed that in attract mode the green leds on the right side of the playfield are also constantly on.
On the left side only the normal lights are on, but the greens are off.
They were working normally before i took it apart. Could I have connected one of the wires to the backbox wrong? I checked it a couple of times, but they all seem to be in order.
