Accordingto Garmin, this problem can be fixed by disabling the WAAS feature in teh set up menu. There is an incompatibility between the old Garmin software and latest WAAS upgrades. Later software from Garmin is supposed to fix this problem.

The outages is one cause for this problem. It could have burnt/damaged the LCD. but before you act on it also consider the fact that the ribbon cable connecting the LCD to the mainboard may have come off. Either way, you must visit the nearest Garmin Service Center and get it rectified.
