Any idea ?
Would you try to build again from scractch at this point ?
If you have replaced the caps and still have 0v after all three components it would suggest to me that that something is shorting that row to GND.
Is you get a narrow bladed hacksaw and it between the tracks and check your cuts again. It shoud be something fairly simple.
Can you post a hi res of the bottom of the board?
