I have noticed that one of my liftmaster LCD screens is blank but still works. I have pushed the Hr and Min buttons and nothing appears on the screen. The light button and the Garage door work from the wall. What could be the problem? Thanks
Common problem; I too had that problem and usually the screen comes back to life as quickly as it went dead. I also have had several homeowners "complain" to me that they also have this issue on their warranty walk thru; I, nor will my garage door installer cover the LiftMaster screens any longer because its a known quark and swapping the key pad out does nothing as the new ones will also go on the fritz and everyone says that they always start working again. Just so were clear, were talking about these right? http://www.liftmaster.com/consumerweb/pages/accessoriesmodeldetail.aspx?modelId=842
