thanks for the quick response. yes, here in Brasil there is still much demand for such equipment, including repair. I would be delighted if someone sent me a list of companies or reliable technicians who work with this line of reconditioned equipment.
Phill, that is a brilliant idea. Work with a circuit board repair, rather than CPAP repair. The shops that are authorized to repair CPAP machines are limited by law in what they can do, and are required to use OEM parts, and make repairs in accordance with medical and manufacturer standards. If you just treat it like a washing machine, you stand a better chance. That said, most circuit boards are considered disposable, however the OEM replacement of a CPAP board costs several hundred dollars.
