White screen may be caused by failed T-CON board or it is not getting the 12vdc or signals from the main board. Check the fuse on the T-CON board first, T-CON board is mounted under the metal shield.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
