Benny - Please know that the Q70C TV’s stand was solidly designed and extensively tested for stability, but there are a few things we’d like you to check:
1. Make sure the stand is correctly installed (all screws aligning, snug in place, etc.).
2. If you need more instruction, refer to the Quick Setup Guide for more help: https://image-us.samsung.com/SamsungUS/samsungbusiness/tv-ci-resources/Q70C_65_to_85in_Install_Guide.pdf
3. Inspect the stand for any cracks, damage, or missing hardware.
If your stand is correctly installed and it still seems crooked/wobbly, please reach Samsung Support and an agent will be happy to help. You can call us at 1-800-SAMSUNG, 8AM - 12AM EST, 7 days a week, or Chat with us on Samsung.com: https://www.samsung.com/us/support/contact/
