yes you have to drill them out have you tried running 12v to it direct to test it? mine wasnt working either an ended up being a transistor on the driver board needing swapped out but its been so long i cant remember what one it was.

I had the same problem on mine. I had to replace an IC chip, U34, on the driver board.

Mine only lit up 1/3 of the way, but checked out OK with 12v. I had to replace the ULN2803A chip at U35 . Soldered in a socket so I can now easily replace the chip if needed. $1 in parts.

So which fix is needed? Mine works intermittantly and the 12v test works so.... I see one person say a transitor on the driver board needed replacing, another said they had to replace an IC chip, U34, on the driver board, and still another had to replace the ULN2803A. chip at U35. I am new to this machine so not sure which item I need to replace much less how to test them, did each have the same problem? I am confused so if any one has any help it would be appreciated!

I'm not sure how to test the chips, so I went ahead and bought a few sockets and a few of both chips. Shipping was more than the ships! I guess I got lucky and started with U35 and it worked. I was going to do U34 next if it didn't.

Guess that's not much help but that was my plan.
