Sears 1/2 hp GDO acting crazy

Our GDO has gone berzerk. It started with working intermittently with the remotes, but was working fine with the wall button. We tried changing batteries in remotes - no change. The green lights on sensors are steady, but the green light on back of main unit flickers constantly. Holding the green button down has no affect. Now garage door opens occasionally by itself, and when we push wall button, door opens, closes, reverses, etc. Even switching electrical wall switch on sometimes activates it. Tried unplugging GDO overnight - no luck. Does anyone know what is happening, or what we can try?

The little green light flickering is normal. If you can hold the green button in and it has no effect you have a bad logic board. It would normally erase the memory so that none of your remotes would work. I think all your problems are tied to this.
