Remove the RS232 board and wash it with clean water and a light brush. Make sure it is well dried out and replace. I am 99% sure this will solve your problem. Some boards had some fluid left on after manufacture and developed this fault, mine included. Washing the board removes the film. I have had no problems since. Use just water of course, no detergents :)
