SOURCE: My Garmin Etrex wont turn on on batteries but it works fine on external usb power.
I have the same problem. The unit works until I connect it to whatever computer via USB (Mac or PC). The screen blanks out as soon as I plug in the USB cable. I have to disconnect the device and only then I am able to turn it on again. That started after Firmware update from V 2.90 to 3.00 . I am not sure this is causing problem. What about the firmware versions of your devices ? Are they all on the latest ?
However, does anybody know if there is a way to go back to firmware version 2.9 if it is not possible anymore to connect the device to any computer (evtl. through putting data on the microSD card ?).
Thanks,
Martin

I have run into the same problem and it may be related to the WAAS (Wide Area Augmentation System) feature. Try disabling this feature (under MAIN MENU / Setup). I used this receiver overseas (Asia and Europe) last year for 35 days straight with no problems. During this time WAAS was disabled as none of these satellites are visible overseas. The problem occurred intermittently prior to the overseas trip, and has reoccurred after returning. I was running into the same problem this past weekend and noticed the screen blanking out (with the vertical line) shortly after differential corrections were applied to the GPS signals. I disabled the WAAS and let the receiver run for over an hour. The problem did not return. Hope this helps.

All Garmin users,
There is no easy solution for this except to return your unit to the nearest Garmin outlet. You need to have very special equipment called an E-Prom burner or writer which only Garmin have. With this equipment they re-programmed (restore) the operating system back on your specific Garmin unit and model.
The problem why anybody can't do it is because there is no way you can access your Garmin unit from a pc or mac if the operating system is lost or damage on your Garmin, for the simple reason your pc or mac can't reconize the device that is pluged in, because there are no communication platform between the two devices.
As simple as that, life with it or send your Garmin gps to an autherized professional Garmin dealer.

Have you checked the fuses in the power cable? There is a reset button under the front bezel. Try pressing that to see if your unit comes back to life too.
Cheers
