I have two Arduino Uno R3 boards and both of them now seem to have an issue. There's a micro sized 8 Pin chip near the dc power port. This seems to get incredibly hot (i managed to get a blister from touching it) and the "L" Led seems to stay dimly lit even when the reset button is pressed.
The Arduino Uno was working fine during operation and only started giving me this problem recently, i cant seem to find any visible short or loose terminal on the board.
I can see that the reset function is being used as my LCD does reset. Would anyone have a reason for this mysterious issue?
