Question
I shorted hot my jenson touch screen radio and now it want come on wut do I do
Disconnect the power entirely for a period of 15 minutes or more. This will reset all the internal electronics. If the problem is a software code corruption this reset will restore it.
If the reset does not help check to make sure you really have power at the unit. Check it with a voltmeter. You may have blown a fuse and you are not getting power as you thought. There are two power lines, maybe three; one is always on coming directly from the battery (through a fuse), one coming from the ignition which turns the unit on and off and the third wire for illumination control/dimming.
If the wiring and power lines are all correct then the unit may have been damaged in which case it will need serviced by an expert who knows how to dig into it.
Good luck.
