Item is damaged before sending

Hi, 

So I am relatively new to selling on eBay (about 5weeks in) & today I listed a handheld game console and it sold within an hour of listing! However, I was selling this item on behalf of a family member who took the photos and I was going to go and pick the item up later in the day. I always test electronic items and video games before listing to ensure they work, so for some reason I just assumed my family member had at least turned the console on. However, upon getting it all home it turns out the LCD in this console is in need of a replacement & I didn’t find that out until after the buyer paid!

I’m so embarrassed this has happened as I try my best to be thorough and honest in my listings, so I’m not sure what to say to the buyer in this situation. I’m also assuming I will receive a strike for cancelling the order?

 

I would thoroughly appreciate some advice! Thank you 🙂
