I have started to say that all "consumer" devices like game consoles, cable boxes Apple TVs, chrome casts etc are not part of my warranty. If the device responds to up/down commands and you see a picture on your TV then it's not my problem. I started doing this with game consoles a year or so ago and now have been doing it with end user devices.

Too many service calls like this and pissed of clients when you hand them a bill for an issue you had nothing todo with. I will gladly hold your hand for my hourly rate but if you cause a panick service call because of your dumbass password then you will get charged.
