Common PXW-Z750 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 →
"BackUp Battery End" message in viewfinder / clock and settings reset each power-up
Likely cause: A dead backup cell cannot retain the real-time clock/config, so settings drop on power-off; only a service battery swap fixes it permanently.
- Step-by-step fixGet the fix →
Battery error: "Use InfoLithium battery only" / C:04, C:23, E:92
Likely cause: The camera refuses to run on a pack it cannot authenticate/monitor to avoid unsafe discharge; genuine communicating cells clear the fault.
- Step-by-step fixGet the fix →
Buffering / dropped frames / recording stops at 4K or high bit-rate
Likely cause: Intra-frame 4K writes need high sustained throughput; under-spec or full cards cannot keep up, so matching media class and freeing space restores headroom.
- Step-by-step fixGet the fix →
C:21:xx moisture condensation warning
Likely cause: Condensation on the optical block/heads can short or fog components; the interlock protects hardware until moisture evaporates.
- Step-by-step fixGet the fix →
Cannot genlock to external reference / external timecode will not lock
Likely cause: Genlock is a frequency-phase reference; a mismatched or absent reference frequency makes phase lock mathematically impossible, and certain special record modes disable the reference path.

How to update firmware / what is the current version
Likely cause: Firmware adds codec/network fixes and stability; a matched, uninterrupted update from genuine media avoids bricking, and current host drivers prevent card-mount problems.

Quick spec / config reference (what am I working with?)
Likely cause: Grounds every other answer: knowing it is a global-shutter 2/3-inch 3-chip B4 broadcast body (not a large-single-sensor cine cam) drives correct advice on lenses, ND, exposure and codecs.

Self-diagnosis code C:13:xx on viewfinder/LCD; card not read/written
Likely cause: C:xx codes are hardware-detected faults; C:13 specifically flags a media/contact read-write failure, so cleaning contacts, swapping cards and reformatting isolates card-vs-slot.
- Step-by-step fixGet the fix →
Self-diagnosis code C:31:xx or C:32:xx
Likely cause: A full 60s power-drain clears transient controller states; a factory reset rules out a corrupt setting.
- Step-by-step fixGet the fix →
Self-diagnosis code E:61:xx
Likely cause: E:6x are higher-severity self-diagnosis faults; the power-drain + reset clears soft errors, but a repeatable E:61 usually means impact-related internal damage.
- Step-by-step fixGet the fix →
Self-diagnosis code E:62:11 or E:62:12 (or any E:xx not otherwise listed)
Likely cause: The 60s drain clears volatile fault latches and a reset clears bad config; a sticking E:62 points to an internal board/sensor fault only service can clear.
