edge programmer.
 

I have an edge evolution for my 01 F350 every now and then the screen would go out. Edge said just unplug it from the cord and plug it back in. That fix worked for years every time the screen went out. Now it doesn't at all and it's programmed on level 3. My question is do I have to buy a whole new programmer or just the screen, where is the stock programming stored. Been thinking about getting the ts six position chip. Any help would be appreciated.
