HDMI port damage on camera and monitor when powered through dummy batteries and multi-tap distribution
What the thread found
- Multiple HDMI ports on both a camera and monitor were damaged simultaneously during operation, requiring service repair, with the failure occurring suddenly during active use after the equipment had been working.
- The damage affected both the camera and monitor connected via HDMI cable with a micro-to-full-size adapter pigtail, all powered through regulated dummy batteries connected to a multi-tap distribution system fed by a V-mount battery.
- Replacing the HDMI cable and pigtail did not restore functionality, indicating the damage was to the ports themselves rather than the cables.
Depends on
- No definitive cause was identified in the discussion.
- The exact power supply configuration and quality of the regulated dummy batteries and multi-tap are unknown.
- No determination was made whether the issue was specific to this power delivery method or could occur with standard on-device batteries.
- A photo intended to clarify the setup did not display properly.
- The specific monitor model was not fully named in the thread.
