NuVo Grand Concerto NV-18GM power problem
I have a GC system installed in 2015 and has worked fine until now. Here is the problem.
WHen I power the system on the blue power indicator light stays on for about 30 seconds and then goes off. No keypads seem to work or any sound coming out.
I figured one of the speaker wires had a short and the unit cut off to protect system. SO I unplugged the network cable and all the speaker connections. Same result.
Fuse at the AC connection is not blown.
What could be wrong here?
Any diagnostics I could try?
Thanks Paul G
