I have an AVR-1604 and it shut itself down abruptly today

Customer Question

I have an AVR-1604 and it shut itself down abruptly today while playing a CD. The standby light blinks continuously twice/second. When selected on, it cycles through its boot-up and when the display indicates "receiver", it shuts down again. I disconnected all speakers suspecting a short but no joy.
JA: What's the make/model number of your stereo? How old is it?
Customer: AVR-1604. 7 years old
JA: What happened right before this popped up? What troubleshooting have you tried?
Customer: Have you read my first statement?
JA: Anything else you want the theater expert to know before I connect you?
Customer: I think that's it. No pop no sparks. Thanks

Hello, I’m Nathan, and I’ll be assisting you today.
Sorry to hear that you’re having trouble with this but I’ll do my best to help you out.

If you disconnect all the speakers and all input sources, will it turn on and stay on all by itself?

Thank you for trying,

Unfortunately that confirms an internal hardware failure. The system is shutting down as part of a protection mode to prevent further damage. There is a fault in the power supply or a short (dc offset condition) in the output stage of the amplifier.

This can happen as the result of damage from a power surge, but is also often just from normal age related wear and tear. I know you said 7 years old, but this is a 2003/2004 model, so it is actually at least 12 years old at this point, and well over doulbe its service life.

While it is possible to fix, it is simply not practical or worthwhile to do so, repairs will easily run you several hundred dollars, more than enough to replace it with a brand new model with updated features (hdmi, networking, etc) and a fresh warranty. That said, I can help with finding a repair shop or replacement recommendations, whichever you prefer.

My apologies for the news.
