Panasonic PT-RQ35K troubleshooting
The Panasonic PT-RQ35K problems live-event techs bring to Ask Roadie most (also called PTRQ35K, RQ35K). Pick your symptom, or describe your own in plain words, and get the likeliest fix first, with the manual page when there is one.
Common PT-RQ35K 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.

Air filter clogging warning / recurring thermal warnings
Likely cause: Restricted airflow is the root cause of most escalating temperature warnings; filter/vent maintenance restores thermal margin.
- Step-by-step fixGet the fix →
Core specs reference — brightness, resolution, weight, power, connectors
Likely cause: Manufacturer spec sheet values; establishes the baseline for every downstream diagnosis (power class, thermal envelope, I/O).
- Step-by-step fixGet the fix →
Image flicker or unstable brightness
Likely cause: On laser 3-chip DLPs, most field flicker is the dynamic-contrast/light-output loop reacting to unstable input timing or a firmware brightness bug rather than a hardware fault; isolating the loop and updating firmware resolves it.

Multi-projector blend/stack: geometry and brightness/contrast matching
Likely cause: Hardware sync plus the geometry/blend engine is how large-venue RQ arrays hold a seamless image; the keystone limits stop techs from over-correcting on short lenses.

Projector looks dim / not reaching rated brightness
Likely cause: The RQ35K derates on 100-120 V mains by design, and Eco/Quiet trade lumens for life/noise; both are the most common causes of unexpected dimness.

Signal flow / integration into a show system (control + long cable runs + SDI)
Likely cause: Maps each show need (control, long haul, SDI, multi-unit sync) to the correct RQ35K terminal/board so integrators wire it right the first time.

Temperature WARNING codes on info monitor: U11 / U12 / U14 / U16
Likely cause: The RQ family uses the same U-series self-diagnosis scheme; warnings flag airflow/thermal margin loss so you can fix cooling before the error-level trip shuts the unit down mid-show.

Which lenses fit, and lens will not zoom/focus or image is soft after a swap
Likely cause: Loose lens-to-mount contacts are the classic cause of dead powered zoom/focus after a swap; reseating and recalibrating restores control.
