After getting sucked into "I bought this to repair it" YouTube I started looking for things on eBay. I was amazed to find that things like PlayStations with declared faults which made them completely unusable were selling at 70-80% the price as things which were sold as working.

The only thing I can imagine is that there is an underground repair business buying broken items to repair them and resell them that was efficient enough to keep the margin between non-working and working that low.
