If a frame has been unplugged while running, or if there has been a power outage or power surge, problems can occur with the display of the frame. It can show as flickering on the screen, as lines going across the screen or it can freeze the display entirely.
Troubleshooting steps:
1.Reboot and unplug the frame
Try to power off the frame from the menu of the screen if possible.
Then unplug the power cord for the frame in both ends (from both the frame and from the outlet) for 5 minutes before plugging it back in again.
2.Try another power adapter
The problem can also be related to the power adapter of the frame.
If you have another identical power adapter lying around, you can test if the screen stops flickering using this instead of the original.
If none of the above seem to solve the problem, please get in touch with retailer to request after-sales treatment. Usually,the corresponding after-sales contact for handling can be found in the purchase link of the product.
