Why we build EnginBox
For more than 20 years we repaired cinema lenses and cameras for rental houses, broadcasters and filmmakers.
We spent countless hours searching for rare service manuals, reverse engineering parts, building our own tools and solving problems without documentation.
Every engineer we met was facing the same challenges.
Valuable knowledge was scattered across hard drives, forums and private chats.
So we decided to build the platform we always wished existed.
EnginBox isn't another startup.
It's the toolbox we built after two decades in the industry.

Probable cause
Faulty Power Distribution Board
The camera doesn't power on due to a failure in the power distribution circuit. This is a known issue on some ALEXA 35.
Recommended actions
1. Inspect all connectors on the power
supply board for signs of oxidation.
2. Check capacitors C11, C12, C14,
and C15 for short circuits.
3. Check the fuse F154
4. Perform system test after board
replacement.

- THE COST OF BEING WRONG
One wrong step
can cost thousands.
Modern cinema and photo equipment is precision-engineered.
Without the right knowledge, the smallest mistake can lead to massive damage.
No documentation. No guidance.
Guesswork leads to broken parts.
Expensive components.
Sensors, boards and optics are not cheap.
Downtime is money.
Every day without your gear costs you.
One mistake. Big consequences.
It's not just a repair - it's your reputation.
Manufacturers don't share everything.
Without proper documentation, even experienced engineers are forced to guess.
- BROKEN LENS
ARRI / Zeiss Master Prime 14 full damaged
Cause: Someone used non‑original, too‑short screws in the PL mount.
Repair cost
$7,500+
- DAMAGED LDS GROUP
ARRI Signature Prime 65 LDS damaged
Cause: The flexible printed circuit (FPC) cable was routed incorrectly. The main LDS board was burned.
Repair cost
$4,000+
- SENSOR UNIT
ARRI Alexa MINI LF ND-Filter module was damaged
Cause: The ND‑filter actuators were lubricated with an incompatible grease, leading to mechanical jamming and eventual failure of the module.
Repair cost
$11,000+
These are real repairs.
They happen every day to engineers who don't have access
to the right manuals, tools and experience.
Don't risk your equipment. Don't risk your reputation.

Michael M.
Senior Lens Technician.
ARRI Service Department.
EU DE
I've been repairing cine lenses for 22 years. Never thought I'd need a platform. But after 6 months with EnginBox, I'm hooked. The docs save me weekly — like last month, found a Cooke manual in 30 seconds that would've taken hours. Plus the CRM actually works the way we do.
Dmitry L.
Owner at OptiService.
Cooke, Zeiss, Angenieux Service.
EU FR
We're a small shop. Every hour counts. EnginBox is constantly saving us — just last month, for example: we found a parts diagram that wasn't anywhere else, and a video guide that showed exactly how to collimate a Angenieux 25-290.
Carlos T.
Senior Technician.
RED Camera & Lens Service.
USA NY
Started repairing cine cameras five years ago. Had a weird RED power board issue — asked EnginBox directly and got a clear fix from a RED specialist who'd dealt with the exact same problem.
Yuriy S.
Senior Lens and Camera Technician.
ARRI, Zeiss, Cooke Service Dept.
RU and MENA
I worked at ARRI for over a decade. This platform was built by real engineers — for themselves, first.
And you can tell.
The docs are real, the repair guides are shot in actual service centers.
This is the real deal.
