Onkyo TX-NR656 No Sound Fix: NG:LCRSL BLBR Error Code Explained

Is your Onkyo TX-NR656 AV receiver locked with no sound and a flashing "NG:LCRSL BLBR" error message on the display? In this video, we open up this home theater amp to diagnose exactly why it is failing its automatic diagnostic check. We track down the root cause of the audio failure, which includes a locked volume wheel and an internal short circuit caused by stray wire pieces sitting directly on the amplifier circuit board. What we cover in this repair breakdown: What the "NG" channel letters mean on an Onkyo display. How the receiver protects itself by cutting off sound and volume control. Finding hidden debris, shorts, and replacing parts to restore audio. Before you throw away your broken receiver or pay for expensive repair shop diagnostics, watch how to check the circuit boards yourself! 🛠️ Saved you $$$ on this repair?
