The display on your Sony DVP-S7700 DVD player still does not turn on, you can try the following steps:

Check the voltage output: Use a multimeter to check if the voltage output is correct from the power supply board to the display board. If the voltage output is incorrect, it may indicate a problem with the power supply board.
Check the display board: Use a multimeter to check if the voltage output is correct from the display board to the display panel. If the voltage output is incorrect, it may indicate a problem with the display board.
Check the backlight: If the display panel is not illuminated, it may indicate a problem with the backlight. You can use a multimeter to check if the backlight is receiving the correct voltage output. If the backlight is not receiving the correct voltage output, it may indicate a problem with the inverter board.
Check the ribbon cables: Inspect the ribbon cables that connect the display board to the display panel for any visible damage or loose connections. Re-seat the cables firmly and securely.
Replace the display panel: If none of the above steps resolve the issue, it may indicate a problem with the display panel itself. You can try replacing the display panel with a new one.
