If everything else is working, hook a spare monitor to the video output, if picture okay! the inverter board just below the screen is more than likely faulty, or the backlight behind the display has failed, but if both show the same symptom it is the video graphics card usually built into the motherboard, I suggest a computer repair shop to address.

If the Touch Sceen is not responding properly, calibrate the touch screen.. Turn the Nuvi off then back on Slide Power key to the right (lock) Hold your finger on the secrren for 30 seconds until the calibration screen appears Follow the on-screen instructions

Your NUM LOCK key is turned on. Look closely at the top row of keys, you should see one that has an icon of a number inside a padlock, or it might say NumLock, NumLk, etc. Press your function key, and while holding it down, press the numlock key as well. You want to press them both at the same time.

You should also see a light somewhere as well. Usually an icon of a number inside a padlock. When you turn Number Lock off, this light will go out.

you get to the touch sceen by holdin down the frist tow buttons and turning the machine on the singer sceen will turn on just touch the sceen and you will see a small black box touch the box and it should move touch it four times and then touch the stright stiche white button at the bottum of the sceen it will save the settings and it will work .

I have posted the answer to this problem if the sceen is misaligned just turn off the machine and hold down the frist to buttons turn the machine back on the singer sceen shows up touch ithe sceen it should freeze and then a small black box should show up touch the box and it should move to a differant spot touch it four times and then rub you finger accross the stright stiche white button at the bottum of the sceen this saves the changes.
