Thanks for the clarification as the use of all Capital Letters - via the internet sounds serious
I have been around a long time doing troubleshooting in the field - as well as from the other side designing and performing failure analysis. The OP seemed to be indicating that it was good quality equipment. That implied to me that the manufacturer might have an interest in helping out. Of course if they have a known design flaw they might try to hide it. If they are a quality unit without known issues then they might be interested in getting to the root if the issue at hand.
I feel it is always worth a try contacting the manufacturer. I agree that it will often not lead to any real assistance but still worth the phone call.
