i have the screen in the link above and i have seen numerous posts that say i can connect it to the 12v on the wii. The screen starts heating up after a minute of it being on. Should i give it less power as it says it can run on 7.5v

It is normal for an LCD to get warm but it shouldn't get too hot.

is there like a temperature that it shouldnt cross

Well for an example, the screen I use says it has a rated operating temperature of -10C~+60C http://www.aliexpress.com/item/4-0-inch-tft-lcd-module/743424611.html?spm=2114.13010608.0.55.H2C1oK

So what part of the LCD is actually getting hot? Have you taken it apart yet?

If you haven't taken it apart I suggest looking at the components coming in from the power jack. More than likely it's using a 7805 or 7808 regulator to step down the 12 volts. I'm basing this assumption off of the fact that the dropout is 7.5v.

These linear regulators burn off the voltage as heat, so they will get hot if you put a high voltage in.
