AV Input with sound but no video
I have a TCL Roku TV and I connected my Wii with a 3 input RCA to AV input adapter (#https://a.co/d/32M5JsA), the sound works but there's no video. Is there a reason why?
IhaveaR_okuTv Make sure the input adapter is firmly seated in the TCL Roku TV. Check the yellow connection to the Wii. It is possible you have a faulty connector. These things are really cheaply made.
