Ordinarily this DVD player would shut itself off if there was not a DVD in it for say, 10 minutes. There will never be a DVD in it again , so we need to keep the screen from turning itself off. Open the base of the unit. Unplug the flat ribbon cable that connects the laser mechanism to the base. In my unit, I never reconnected these parts.
Look at the area where the display connects to the mainboard. In every one of these devices that I've seen, there is a section of the board that looks like a secondary power supply. Note here the small voltage regulator, transformer, and capacitors.
