Been trying to contact the e-bay seller about the TBS 5980, power supply, etc. No luck so far. In the meanwhile I have been using it with a stable power supply, but the last few times I had it running it quits after about 5 minutes. This am it only worked for about a minute, then the receiver stopped working. Not long enough to do a blind scan etc. Repeated a while after againwith the same results. I suspect there is damage to the unit from the problematic power supply and it has just about completely failed, likely an overheated semiconductor. Doesn't seem to be warrenty (seller doesn't respond), so it would seem this was a waste of $70. I don't think there is any point in contacting a different seller (US based?) for warranty replacment/service, wouldn't be fair to them, unless they might have a suggestion or contact info for the people I originally purchased the device from I suppose...
