A blacked-out screen on a Jensen UV7i can be caused by several factors, including a loose or damaged connection, a software glitch, or a power issue. Ensure that the device is properly powered and check the connections for any loose cables. If the issue persists, performing a reset or updating the firmware may help resolve the problem. If these steps do not work, the device may need professional servicing.

You know that is a safety to keep people from watching T.V. while driving down road? It keeps you from killing a family because you crossover center line while watching PowerRangers The Movie for the 100th time.
Well you can run the pink wire to the fuse box then add a switch.....When prompt to do so turn switch on for five seconds......Then turn it back off.....Then turn back on and leave on....TV will come on in 1-2 seconds.
