So I have a controller with a persistent red screen. Old thread (and other similar) says:
I have done the above with the a brain on its own and the brain connected to computer, VexCodeV5 running, brain discovered. Nothing happens.
Devices on brain does not find controller. Controller v5 ports blinking red. Reset button back of controller is the only way to power the controller off. Power on, connect to brain by cable or connect to computer by usb all power controller on at red screen.
Its old, is it dead?
Edit: FWIW the controller is slightly warm a bit right of the A button at the base of the right joystick and around toward R1.
