Respuesta a "My GPS Garmin NUVI785 does not turn on"With power cable attached, try holding the power button for 10-20 seconds until the Garmin resets. Mine will fail to turn on or lock up sometimes and this reset procedure will bring it back.
Respuesta a "Why is my screen turning pink?"Video cable is more likely than the whole display, motherboard, etc. Test as jayeff suggests. The video cable has to go through the hinge and after a while gets damaged from flexing. First thing to try is readjusting the cable slightly to give more slack at the hinge point. May mitigate the pink screen problem.
