Water crept in below the glass
After years of excellent service, my Forerunner probably lost is waterproof and I found moisture (actually some water) underneath the glass, over the LCD panel. So yesterday, after my run, I could not turn it off and the display kept changing randomly. It worked during the training, though.
I, probably, have to open it, if it is still fixable.
Any instruction on how to fix it?
Is this a good question?
