Canon 70D lens issue
Whenever I attach a zoom lens into my camera, use my LCD instead of my viewfinder then if I zoom in and then zoom out, my LCD goes blank and it switches to my viewfinder, sometimes I get this error :

Here's a video I recorded:
This is bad because I have a gig tomorrow.
P.S the lens cap was off, it was just dark in my room.

^ this seems to be an issue similar to mine.
What I have tried doing :
Cleaning my camera and contact lens, trying my lens on another camera which made me realize theres a problem with my Canon 70d.
