Pink/purple spot on screen / helium sensor

[Luka Rukavina]

Hi all!

Did anybody have an issue with a small spot on screen on their helium (or other) cameras? It looks purple on RED's LCD and a bit more pink on computer monitor when looking at the footages.

It stays there the whole time but it is not visible when camera points at bright daylight or totally dark areas.

The problem persists even when I switch lenses or have no lens at all.

Everything regarding optics is clean from debris and I even blackshaded again but the issue remains.

Last time everything was ok was just two days before on my last shoot and I had no lasers, strange lights etc on set to damage the sensor. It was a controlled shoot in daylight with normal additional lights (ARRI, LED panels).

It looks something like on picture attached, small but visible. I can provide with a single R3D frame for example.

Any thoughts?

Hey Luke,

I’d say first, if you haven’t, do some testing checking the usual suspects.
Make sure your temps are in the green and do some manual black shades.

Best case scenario they could maybe be some stuck pixels.
If that, and what other people advise to try doesn’t work, I’d say get in contact with RED.

Might be a good idea to export that .r3d frame as a .r3d as well.

Hope that helps.

Hi Brandon,

I checked all of that, green lights, temperature, did the manual blackshade, all of that...but nothing changes. The camera looks and acts normally except that issue on the screen and footage.

And it doesn't look like a hot/dead pixel because it doesn't look like some "rightly shaped" dot, it is bigger than just one or two pixels and it is shaped like some kind of smudge when I zoom in.

I already contacted bomb squad and sent them .r3d file to check. The picture I attached here is not mine - it just looks exactly the same.

Thanks for your advices anyway!
