I am looking at a TV cabinet like you describe. We have converted it to a computer printer cabinet. If I hit that door with a 60G impact, the heavy door would be damaged.

I could tell from your write-up that this was an anxiety issue and your anxiety was trying to convince you that this cabinet door did damage.

As I tell others who post anxiety ridden posts like this, I will not enable your anxiety with an answer.

I hope you will answer this one question.

What difference does it make whether the impact was damaging or not?

It already happened.
