Build In Self Test LCD
Caveat
I have designed (circa '99) integrated micro KOPIN LCD displays to display VGA and VCR signals, yet I have no experience with your monitor, but I recognize the blooming effects.

LCD simple Theory of Operation

We know the pixels are addressed in a matrix of rows and columns with the pixel clock, but the analog characteristics are refreshed as a differential charge voltage at some bias voltage defined as a White (W) level DC Restorer circuit. It switch clamps each signal momentarily during the horizontal blanking interval to this V_w level.    

Each video signal must be AC coupled to do this.  ( Verify) or else DC bias exactly to the differential voltage specs in a range within the Analog voltage.

The bias level enables a polarized dielectric to hold a charge with low leakage in between the White and Black levels defined by internal voltages. Otherwise leakage currents decay the black to white and covering the screen with fog starting around the edges.  A black signal would look like large pulse signals ||______|| in both polarities. 
 A white signal will look like small pulse near the blanking interval values.|_----------__--- ( not exactly)

When the DC restore circuit stops working or clamps on inverted differential signals ( verify) or puts the applied charge where it causes the overall voltage reference to be wrong, then it starts to bloom around the edges as in your video.

But since you have not even a ghost of any test patterns , it may be a simple problem.  Perhaps you can verify the analog signals to be valid then the clocks for pixel clock , V sync, H sync pulses are valid etc or the chip is biased wrong.
