Heh, as I thought ..kinda puts the kibosh on suggesting Sandton, dunnit? But, in a manner of speaking, Slaapstad is a major metropol so why not ask "support" (sorry, but you just have to suffer through this one) where to take/send it in CPT?
I've had 2 UTD's in the last week that were dead and it turned out to just be blown power supplies. iBurst will send you a replacement for around R200 or you can take your chances on a 9v / 1.2A powersupply from your local electronics shop.
