I've had my AE1000 for around 9 months now, and it's just developed what appears to be a fault. On powering up after say a few hours, it'll run for a few mins, then intermittently go into standby mode. Trying to turn it back on using the remote doesn't work, although giving it a few seconds, turning it off, then back on, then powering up, gets it working fine. The unit has around 800 hours on it. Any thoughts? It's still under warranty, so I'm not too worried at the moment, but would like to have it resolved.
