Hi,

Before anything else, please be in mind that those displays can't be connected directly to the Arduino pins. The display is powered by 5V but the logic interface is 3.3V so you will need a logic level converter, for all the control lines. If you connect the display directly to pins with a 5V level usually it will damage them.

Had you removed the diode on the Meduino Mega2560 Pro-mini board before using it on the Pro2 PLUS board?
Does the 3.3V regulator seems to be quite hot?

If you are sure the TFT display is good, and it still don't display anything when connected to the Pro2 PLUS board, them, most probably the chip which acts as logic level converted becomes damaged.
If the diode on the Meduino board wasn't removed, unplugging the 9v power supply while keeping the board connected by USB, could cause the damage of the logic level chip.
