The problem is a physical one, not a software issue.
I assume some sort of loose connection(s) at the screen or failure in the hardware.
Have been reluctant to dis-assemble without advice/guidance from someone that has experienced and solved the problem.
Can not update software as no link cable comes with unit.
Recently attempted to construct one ( found directions online for home made version) but needed a different type of wire than I had available at the time. (cost to purchase one from Garmin prohibitive for my uses) I have repaired an unresponsive Dell Axim x5 screen by dis-assembling and placing tape over a burnt ribbon connector so I am not afraid to work on the unit provided some success is possible. Not knowledgeable enough to just look for something that might not be apparent to the untrained eye with the risk of damaging the unit further. The unit is usable just difficult to read.
This is not the "thin black line display only" problem
The screen is for the most part visible. Several horizontal rows of pixels are not on (black where it should be) but rather always off (no image) Some in groups others alone. Apparently random but always the same on all pages all the time, every time.

Update the unit software and please report back if this fixes the problem.

Horz blank lines. First appeared after not using for some time.
Magellan Explorist 200 has horizontal lines through the entire screen which makes text appear distorted.
