To understand why this happened, one must look at the receiver’s digital architecture. The update aimed to improve HDMI handshaking with HDCP 2.2 (copy protection) and enhance Dolby Vision pass-through. In doing so, it likely altered the power management states of two key components: the main DSP (Digital Signal Processor) and the HDMI switching board. Evidence from user diagnostics and service technician reports suggests the update disabled or bypassed certain low-power idle modes. In essence, the software commanded the receiver’s processing cores to run at a higher operational state constantly, never dropping to a “sleep” or “standby low-power” mode when no audio signal was present. This caused a sustained power draw, translating directly into excess waste heat.
