So recently I bought an lcd screen controller board along with a respberry pi to re-use an old laptop screen.
To power it I bought a 12V 5A power supply. The problem is that when I power the whole thing, it works, but the controller board starts heating a lot, to the point where it slighly hurt touching it with the finger after ~20 seconds, so I turn it off.
My question is is it normal? Did I do something wrong about it or is it already working as intended?
Thanks in advance!
