Model TP550LAB screen issues

I have 2 model TP550LAB laptops. These are the models which can be used as a laptop or a tablet. About a year ago, one of them began doing the following: When the laptop is taken off the charger, even when the battery is full, the screen will flash over and over to the point that you can not do anything on it. Sometimes it will black out completely. You can hear the sounds on the computer but just the screen is out. Well about a month and half later, the other laptop started doing the exact same thing. Obviously, this is an issue, as I can not unplug my laptop at all. When they started doing it, it was once in a while. The first time I was at a friends house trying to use it. Now, both of them do it every single time they are unplugged. I have tried some obvious stuff like changing outlets. We have tried them at completely different houses. I find it strange that they both began to do the same thing within weeks of eachother. They were both purchased the same day. The 2nd laptop is not used as often as the first. I have done updates to see if it was a software issue. I am at a loss. Any ideas?
