Since the data is probably not syncronised with the mains, the end result is the amazing racket we are used to.From the symptoms you describe, I agree with your diagnosis.It is definitely a power supply problem, possibly caused by faulty filter capacitors. OK. Who is going to write to them? Mike -- M.J.Powell |
