Nokia 1616 LCD AVR Issue
Have you thoroughly inspected your PCB for shorts? 

You can use a continuity tester function (or the lowest ohm range) of a multimeter to test whether you have shorts between traces that shouldn't be shorted (do this with power disconnected!). 

Better if you do this test with the LCD (and any other socketed component) disconnected, so as to minimize apparent shorts due to their presence.

This, together with visual inspection using a good loupe, should give enough confidence about the presence of shorts due to the PCB fabrication or the soldering step.

Keep in mind that, since you already have some component soldered, if you find a short it could be due to a component placed between the traces where you detect the short, so you should desolder every component and test them individually, unless you spot a dead short between the traces due to fabrication residues or soldering.
