My Forerunner 245 appeared dead pixels on left screen few days ago.
I saw many users here have the same problem.
I contacted the Garmin Thailand and they said if my Forerunner is over 2 years, I need to pay money around 120 USD for a new one and get 3 months of warranty.
But if I don't want to pay money, they suggest me to wait until new model is launched and buy a new one!!!
But this problem is a global issues for this Forerunner.
I've never had problem before until I updated the software.
Garmin should have more responsibility to solve this problem.
