Can I check whether the TV in the hotel is broken?

This problem should be divided into the burden of proof. First of all, the hotel should prove that the TV is good before you check in. If they can't prove that he bears the loss, if he can prove it, you have to bear it. Of course, if you can prove that it was damaged for other reasons, you don't have to bear it. In general, it is difficult for hotels to provide evidence, so it is likely to be borne by hotels.
