@justenmoody U5 (yes, the whole board is U5) should be the power supply board regulator board. It supplies the 5V and 13.6V and -15V. The 13.6V and -15V are used to power your screen. I have not found a schematic for this yet. There are replacements out there (not cheap). Something [link|https://handheldlegend.com/products/game-boy-color-original-power-regulator?variant=39771581546630¤cy=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gclid=Cj0KCQjwjt-oBhDKARIsABVRB0zyCZxHXN_MEjpBUoHgqV-M8QkJ4AI41_ulTdBEm_qRzb7O_qWY8b8aAu4dEALw_wcB|like this] will work since it supplies the same voltages. You can't use the ones for the IPS screen since they only require 5V for the LCD.

you would probably get away with replacing your board with any buck converter that supplies the required voltages.

Just out of curiosity, have you tried to solder it back on the way it belongs and measured the output? It will not work the way it is :-)
