While the screen is connected try touching the CHESTNUT Chip and see if it is heating.

If it heats your need to change the CHESTNUT.

You can even check if the touch connector on motherboard is damaged.

And make sure the touch connector is properly connected while conmecting the LCD.

Hope that helps.

Have you checked the backlight circuit? If you do not disconnect the battery when you mount or disassemble the display you can interrupt the power supply of the backlight.
