Common Pyro Series errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.
- Step-by-step fixGet the fix →
Camera's own screen goes black when it starts recording 4K (feed to Pyro TX)
Likely cause: The camera's HDMI and internal display share one video pipe at 4K; routing through a recorder gives the TX its own clean output.
- Step-by-step fixGet the fix →
Connect a phone/tablet to the Pyro TX with the HollyView app
Likely cause: The TX broadcasts its own Wi-Fi AP; the app rides that link for monitoring and can push RTMP out through a phone's data connection.

Firmware update procedure for Pyro H / Pyro S / Pyro 7 (USB method)
Likely cause: The bootloader only reads FAT32 volumes <=32GB from root; interrupting power or removing the drive mid-write is what bricks these units, and version jumps must respect the required stepping.
- Step-by-step fixGet the fix →
Freezing / mosaic specifically on the HollyView app image (phone/tablet)
Likely cause: RF overload at very short range desensitizes the phone radio; backing off 2m clears it.

How to pair a new/replacement receiver to an existing Pyro system
Likely cause: Pyro pairs by matched group ID rather than a button handshake, so aligning the group is the whole pairing step.
- Step-by-step fixGet the fix →
Pyro S bricked / unresponsive after a failed firmware upgrade
Likely cause: Flashing the base image rewrites the bootloader/partition a failed update left half-written, giving a clean floor to upgrade from.
- Step-by-step fixGet the fix →
Receiver drops / loses connection to transmitter that is otherwise working
Likely cause: RX dropouts are usually undervoltage or RF congestion; fresh power plus a clean channel plus a clean re-pair restores a stable receiver.

Sony mirrorless/DSLR HDMI screen goes black when connected to Pyro TX
Likely cause: Sony bodies drop the clean HDMI feed when Info Display / HDMI Control handshake or a 4K output mode conflicts with the receiving device; forcing 1080p and disabling the control lines restores a clean output.
- Step-by-step fixGet the fix →
Video freezing, blurriness, mosaic/blocking artifacts on the link
Likely cause: Mosaic and freezing come from RF interference or brownout; a clean channel plus correct antennas plus stable power restores link margin.
