Hi wondering if I can get some asistnce with my HTR-5790, for the third time I have had it repaired in the last 2 months, the first time it went out I was told by the technician that he had to replace 3 trans. I took it home hooked it up then 3 days later it did it again it shut off and only would turn on for a few seconds then click off before any sound woukld come out, so I had it repaired took it home this time 5 days later same problem, even afetr I disconnected all the components and speakers still would not stay on, could the problem be from a shorted speaker, please advise..
