hi man... may be few things:

1.- check your lcd conector on board, try to resolder it, perhaps any point is desoldered

2.-It could be a common problem on 3200 and 6100, many kinds of lcd controler (on lcd) are not compatible with mcu version, try to upgrade or downgrade your phone´s firmaware or simply lcd contrler is not compatible with your board, for example, original displays with philips controler are compatible with almost every phone (you can notice orange flex circuit on lcd), other ver. of lcd controler may not be compatible with your phone (green flex display)

3.- check your lcd conector, it can be damage as the lcd board conector is, this is a common problem too.

4.- reflow upp, as lthe last solution
