LW Pro only poor or fair quality
 

When i first got Pro a few months ago, the quality was always turbocharged like it's supposed to be, but about two weeks ago one day, it suddenly stopped that and now the best i can get out of it is Fair or fluctuating between Poor and Fair. If i wait long enough and watch it closely, it will go to turbocharged, but only for a minute and then it goes right back down.
