"Creating the best products and experiences for our customers is our top
priority. We have heard your feedback and after careful examination, have
determined that a small percentage of Surface Pro 4 devices are exhibiting a
flickering or scrambled screen that cannot be addressed with a firmware or
driver update. To support customers affected by this issue, we will replace
eligible Surface Pro 4 devices for up to three years from the date of purchase,
free of charge.
Replacement Process
First, ensure that you have taken all the latest Surface and Windows Updates.
Surface and Windows updates are designed to keep your device running in an
optimal state. If the flickering or scrambling persists on the screen with all
current updates installed, please contact Microsoft support
https://support.microsoft.com/en-us/help/4051701. Once an agent has determined
that your device is eligible for replacement, you will need to prepare your
Surface for service. We will ship you a replacement device as soon as you return
your existing device. Typically, it will take 5-8 business days for you to
receive an exchange device from the date that you ship your current device back
to us."
