help!! docking my refurbished Switch with the travel dock and getting this on teh TV in teh bedroom:

No Signal
HDMI 2
Check the cable connection and the input source.
the console does seem to detect teh dock. befroe I order a new one, what can I test at home?
If anyone has had the same thing and fixed it, Id love to hear what worked 🤷 Ill report back with whatever i find.
Id rather not buy a new dock if its smth simple. If theres a reset or a specific order to plug things in, please let me know. im about to throw this thing out the window lol
