W/o being able to look at it, I don't know what else to tell you? IF circuit board is faulty, I don't know what else, except replace lamp assembly?
Just for testing, you could try using separate voltage wires, jumper wires off battery voltage. Use separate jumper wires from one side to the other, so one side can't kill the other side. See if brake lamps will stay on. You don't have to use brake pedal. With the jumper, you might use an inline fuse, just in case.
If the stop lamps come on and stay on, I don't think it is the lamp assembly. I've been racking my brain trying to figure something w/o being able to look at vehicle. I'm about at the end of my rope. Lol
