i just recently had someone bring in a roomba discovery and all it would do is stay in a tight 4 tile area and go in circles. battery was fully charged and all bumpers were clear.
i took a can of air blast for cleaning computers and blasted the area on the bottom underneath the sensor and watched as several dust bunnies came flying out.gave it a few more blasts for good measure and put it back on the floor and hit power then clean buttons.
thing went in same tight circle for 2 passes then the circle got bigger for 2 more passes , blue light indicator came on and it made a straight line dash across to closed door and started following the edge and criss-crossing the room.
called the owner back in to test and it repeated the same moves when she started it and all appeared to be working normal again.

Pressing your positive button will make your screen move right. Adjust your screen until the black on both sides are of even proportion. Then, press the menu button to return to the orginal menu you started at. Proceed to press your positive button two more times. Then, press your menu button. Then, once again, use your positive button, and your negative button to adjust your screen to even out the black on the top and bottom.
