When I have seen this problem in the past it generally means it is time for a new unit or a repair. It is a hardware issue that a user can not fix. For your local repair depot please contact Garmin @ 1-800-800-1020

My Garmin Etrex Legend starts up and finds the satellites, but then screen goes blank except for vertical line on the screen.Stays that way until batteries wear out. Fixable?


I have the same Garmin product. It had a problem displaying anything. I went to the Garmin web site and got tech support. They fixed the problem by telling me what to do. Try them befor you throw it away. But it sounds un-repairable

Screen goes blank after locating sattilites.


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.

I have a Garmin etrex Legend about 5 yrs old. After I turn it on and it gets the coordinates, the screen will go blank except for 1 vertical line thru it. Also, I get no response from any of the buttons,...


You have to update the unit's software from the Garmin site. A new satellite was launched last year which causes this problem. Updating the software fixes it.

If this solves your problem, please come back and rate the post as "fixed". Thanks

Just quits


I had the same problem (blank screen, vertical line). Per Garmin, turn off the WAAS function. Disable it for now, because the government has changed the WAAS signal coming from the satillite, and Garmin has not yet come out with a remedy to correct this problem yet. It should be out in a software update sometime in the future...............I did this and it corrected my problem immediately. The unit performs perfectly now, however, the accuracy is not as good, due to the lack of WAAS.......................

Screen goes blank except for a verticle streak


I had the same problem (blank screen, vertical line). After speaking with Garmin, I was told to make sure I was using the latest software version, and to turn off the WAAS function. Disable it for now, because the WAAS signal, coming from the satellite, has changed, and Garmin has not yet published a remedy to correct this problem. A fix should be out in a software update, sometime in the future, hopefully. I also did the software update, to the latest version 4.0. The unit performs perfectly now, however, the accuracy is not quite as good, due to the lack of WAAS. Good Luck!!

Screen goes blank except for a black line


I had the same problem with my 76S. Called Garmin to send it back for service. They said it was a problem with new WAAS signals that causes the freeze/black line. Disabling WAAS using menu/system solved it for now. They are working on a software update Real Soon Now.

Blank Screen on Garmin E-Trex Vista


The problem is that your software version needs updating. A recently added satellite creates a glitch in the older software. Go to the Garmin website, load WebUpdater if you haven't already done so, and the updated version (3.8) will automatically install to your Garmin unit. I had the same symptoms, they have now disappeared and my Etrex Vista is back to normal.
