I have had my transporter for over two years now with no problems but yesterday it started cycling between on and off (the logo pops up onto the screen) every 10 seconds after working normally for about 10 minutes. I can hear the relays inside the unit clicking as it cycles. I am running software version 7.5.3. Does anyone know anything about these things? Or does anyone know where in Joburg I can take it to be seen to? I bought it from a local online store in 2009 so i am assuming no warranty.
