I still can't solve the 4 by 4.

I start from the bottom working way up. Bottom row is row 1.

I start lighting row 1 by pressing row two.

I continue up to row 3 to light row 2.

I continue up to the last row or row 4 to light row 2.

according to all the threads...

The top row should be lit....

However it isn't...

Any help...
