I feel for you man, mine lasted 12 YRS and served me well . One day I went in to play , no audio at all , I thought it was a firmware issue ( I’ve loaded 2 of them successfully) downloaded the latest software,this time the display went blank,still lit up , no lights on the buttons . It would not connect the the VIRUS TI went through all the rituals of loading and holding buttons. Turned out I was not getting any reaction from my unit, It was suggested I contact my nearest authorized service center in Texas I live in Denver ,and there reviews were not very good on this particular service center, to put it straight ,I don’t live by reviews, however ,some of the points they made were simmular to the ones I’ve experienced on other instruments I had serviced.
