I really like this Garmin Forerunner 210, but twice it just gave me a blank screen and nothing else. After some research on the net I found some reset methods: (note: these were not always for the 210 model but until now method 1 and 2 worked for me; you may need method 3 one day …)
Press the lap/reset button a few seconds and then press the light button to switch on the Garmin device again. Pressing both lap/reset and the light button may work better: keep both buttons pressed for several seconds until the 210 watch is “reanimated” again.
If this fails you can try the hard reset; keep the following 3 buttons pressed together during some seconds: page/menu, lap/reset and light. Release the buttons and press the light button again.
Soft Reset: keep the page/menu and lap/reset pressed for a few seconds.
Update – 25/01/2014:
Garmin released a firmware update, which should fix this issue. I installed it today: hope it really helps 😉
Changes made from version 2.60 to 2.70:
- Fixed an issue where the device could display a blank screen while connected to the charger.
