Any 3808CI troubleshooting tips?
Have a 3808CI that has recently developed a thermal issue where it takes about 2-4 minutes after powering on before the AVR becomes stable. During this unstable warm up period it will repeatedly flip between displaying the current video source input (HDMI) and switching to searching for source input (presumably losing the current source input?). It's doing this with multiple HDMI input sources, so the problem appears to be with the AVR itself. Once the system warms up it works perfectly fine. Though the warm up period has been slowly growing so I expect at some point it's going to be fatal if unresolved.
Going to open up the AVR, dust everything out, and make sure anything pluggable or socketed is seated well since I know connections are a common source of these sorts of thermal issues. Also going to do some bench testing with other input and display devices to confirm precisely what's happening.
Any suggestions on things to check out in the AVR are appreciated. Did some searching in the thread, but couldn't identify if other folks had experienced similar issues in the past?
