Viore is another badge name for sets put out by a company called DSI. They also distribute ILO and Akai badged sets.
Unfortunately, while my service company does "attempt" to repair Viore, we aren't always successful. Mostly due to the absolute lack of support by the company when it comes to service after the sale. Their parts situation is pathetic and we have a great deal of difficulty getting any sort of technical support from them. They just plain ignore us.
What cities do you guys live in? I might be able to direct you to one of our service centers close to you. We can at least try and effect repairs as we are authorized on Viore's.
