Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
No power	Fuse, power supply	Check F101 (2A); measure standby voltage; replace power IC.
No disc reading	Laser, spindle motor	Clean lens; check RF amplitude; replace pickup if <0.6Vpp.
No video output	Video processor, cables	Check video DAC output; replace U301 if no signal.
No audio output	Audio DAC, op-amps	Verify digital input to U401; check ±15V supplies.
HDMI no signal	HDMI chip, connection	Check 3.3V supply to U501; replace HDMI transmitter.

Reset: Power cycle or service mode initialization.
