Jandy Lite2 controller blinking and can't program

I opened my 24' round pool last week and when I started up the Lite2 it worked. The next day I noticed that every graphic on the controller panel was blinking. I tried some of the keys and none of them worked. There are no error codes flashing (because all the graphics are blinking).

    Bad controller was my problem. From now on I will be disconnecting my controller and will be bringing it inside my house out of the cold climate here in Canada. It's just 4 screws and a ribbon cable. Hope this helps other Jandy lite 2 owners.

I had the same problem and a friend of mine told me that the board is shot and needs to be replaced. I got a new board and installed it just now and everything is working fine now. The back of the board looked a little fried. If you can take the board out which is connected by a ribbon cord and plug and 4 screws on front. It might be possibly fixed by an electronic person or else you will have to get a whole new board $275. Sorry
