Measure you Vs voltage to see if it is correct when picture is displayed and again when the picture display is lost. The voltages for Vs, Va. Vsc, -Ve would be on a label attached to the panel.

They are correct voltage is there when there is no picture

Then that could be a Panel or FFC issue. Check ALL the connectors to ensure they are clean and properly seated and the FFCs are in good repair.
