My V50 display was working but the screen is black and it’s not working now.

1. Ensure that the wall plug power outlet is working. Try plugging something else into the same outlet or moving the V50 to another known working outlet.
2. If the wall plug power outlet is confirmed working, and the weather display will not turn on, then it might need to be completely power cycled.
   1. Unplug the AC adapter from the wall.
   2. Remove the small battery cover on the back of the display. Use a quarter or other coin to turn it counterclockwise. 
   3. Remove the coin cell battery from the display.
3. Plug in the wall adapter and confirm the display turns on and starts to work again.
   
   
4. Re-install the battery again and install the cover.
