What you'll notice
The recorder is running (lights, beeps, app works) but the connected TV or monitor shows no signal.
Why it happens
Output resolution set higher than the display supports, a failed HDMI port, or the wrong input selected on the screen.
How we fix it
We recover the output resolution via the app or a VGA fallback, test the ports, and configure a resolution every connected display can handle.
Still not working?
If the checks above haven't restored your dvr (digital video recorder), this usually needs a technician. Our DVR Repairs service covers exactly this fault.
