Canon 70d lens contact error

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. However if I work with my camera for a little bit (so it warms up lol) the issue stops occurring

Sounds like it could be a camera hardware issue. As was suggested in the other post you referenced my recommendation would be to call Canon support. In the US Canon team is available weekdays from 9am to 6pm (ET) at 800-OK-CANON (800-652-2666).
