Hello everyone, I hope this is the right place for this.

I have a light leak problem on my XTR prod, it's a strong red flashing cast that comes across the image fairly sporadically, I have attached an example video:

I thought it might be the viewfinder glow somehow leaking through the gate, however I thought when I was filming this the glow was off, but I can't be 100% sure.

I have found two other posts from the forum about this kind of problem:

But I'd like to post about my specific problem with examples here to see if anyone might know definitively what causes it. 

I am based in the UK and I am going to get the camera serviced and hopefully fixed, but in order to chase down this particular problem I thought I would ask here and see if anyone else has had this problem and what solutions  they found please?

Here are video examples from my camera:

The password for both videos is: leaky

Thanks for taking the time to read my post, please can anyone let me know if they've seen the same thing and is it a simple fix? ?

Thanks,

Eddie
