AVR problems

Real buyer questions on avr problems, answered in plain terms.

My AVR's control app can't find the receiver, even though the receiver is on the network. How do I fix it?

This is a network problem wearing an AVR costume, and the fix is almost always on the router or the phone, not in the receiver.

AVR problems
Some days my AVR gives no picture or sound when everything turns on β€” until I switch it off and on again. Why?

Intermittent HDMI handshake failure. When source, AVR and TV all wake at once, the negotiation between them (HDCP authentication and EDID, the TV telling the chain what it can display) occasionally completes wrong, and a power cycle forces a clean renegotiation. It is not a fault as such, it is a race, and you can make it rare or gone.

AVR problems
Auto-calibration keeps failing with errors like 'speaker none', phase warnings, or speaker-matching errors. What do they mean?

Each error points somewhere specific, and almost all of them are wiring or noise rather than the AVR. Read the error, then look at the thing it names.

AVR problems
My AVR turns itself on at odd hours. Is it haunted?

Not haunted, networked. Something on the same HDMI chain or the same Wi-Fi is waking it, and there are three usual suspects.

AVR problems
My receiver shuts itself off when I turn the volume up (or randomly mid-movie). Why?

It is protecting itself, and the trigger is one of three things: heat, load, or supply. The pattern of when it happens tells you which.

AVR problems
My AV receiver went into 'protection mode' (or just blinks its standby light and won't turn on). What now?

Protection mode means the AVR caught a short, or thinks it did, and locked itself to survive. The circuit is doing its job. Your job is to find the short instead of fighting it.

AVR problems
The auto-calibration says my subwoofer isn't detected (or the sub went silent after calibration). What's wrong?

Settings, not hardware, nine times out of ten. Do not carry the sub anywhere yet.
