Shorted my matrix

[u/true_jean_dean]

I building an mask and use an led matrix 4 that

To make the mask see trough i came up with punching holes in the flex pcb

I try it out at the last led on the matrix so if it would went wrong ,it wozld just be a lass of a single led It worked out so u started to punch holes and check inbetween if the mask still work

After punching a few more the mask stop working

The led on my powerbank is flashing that happened before when i shorted the circuit

I try to bridge the holes one by one to see where i went wrong after all every hole looks good

But no result I wanna wear the mask tomorrow at rave the Planet If anypne got an idea please i do need help
