LCD is dark - plug in charger lights up for split second

Got a Nanon 4th generation, 8GB. The LCD is totally dim, did a factory reset ... weird thing is if I plug in the charging cable in from time to time it lights up fully for a split second then goes dim. But not all the time.

Guessed it might be just a loose lcd cable, but jiggled, tapped, etc, with no results or flicker.

Figure I will just order in a new lcd, but just wondering if someone has experienced the same issue (just kinda voodoo weird) out of curiosity.
