This Sony Sync TV Data Cable links your TV to the external Sony ACDP power adapter. It carries DC power and the low-speed ID/sync signal so the TV can recognize the adapter and power on at the correct wattage. (Not HDMI/USB; no audio/video.)
Fixes common issues
TV won’t power on with the ACDP adapter connected
Random shut-offs or power-cycling/boot loops
“Adapter not recognized”/status LED error patterns related to the DC-in lead
Intermittent startup (works only after multiple tries)
TV won’t wake from standby or loses power when moved/bumped
Loose, damaged or missing original DC-in/sync cable
