Marc, look at the connector 1 for LCD, it may be damaged or dirty. Try turning phone off, reopen and clean the connectors. Make sure that the pins that connect to the flex aren't damaged and that all the pins are soldered to the motherboard. Of course you did power your phone off before you did the repair. Otherwise it is possible that you shorted out on the motherboard. Check the board to see if you find any charred or missing components, focus on the filters for the LCD. I am sure you already tried a hard reset to make sure that the white screen is not software related.
