Sony DSC RX100 M2 LCD screen not working

Hello,

I recently purchased a RX100 M2 from eBay. The seller stated the LCD screen needed to be replaced, the camera had been stepped on and shortly after the LCD stopped working.  I have replaced the LCD with a new part and the screen does not light up.  I also replaced the ribbon cable on the folding screen mount and the LC1110 Video Control Board, thinking they may be bad.  After installing a second new LCD screen it still doesn't light up.

Has anyone had a similar problem or knows of a solution?
