The picture screen is completely black. If i switch it on and on again sometimes the picture will come up. Qatched it yesterday, and today the screen is totally black again but the volume is fine. Was wondering if you have any idea what the problem is or if it was even worth fixing.
Thanks, Stephanie
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main digital board.

If there is a PIN assigned and the PIN can't be entered in because the touchscreen isn't working, then the PC will not recognize it. The communication routines between the Nuvi and PC will only happen after the PIN has been entered. If your at home, you will get to the main menu because that's your safe location where it will not ask for a PIN. The touchscreen is bad and needs to be replaced. Please see this link:
