No Display with TAS620

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a TAS620 displaying on a G600. A couple of years ago the G600 was showing no targets although the traffic page showed is was connected to the TAS with no faults. The unit was sent in for repair and came back with "replaced Q7 on 65-2007" as the service performed. Everything worked OK for awhile.Now I have the same problem. No faults, but no display. I don't have any audible alerts either. 
This was a fairly expensive repair, and I'd prefer not to have this be a repeating event. 
My avionics shop/Avidyne dealer has checked the configuration as best they can and everything seems OK. 
Looking for ideas.

	This apears to be a big problem that Avidyne is ignoring. The most likely repsonse is to add a Skytrax for $4k, but it is mainly fot TIS B traffic.
