I bought my TCL Roku TV a month ago and it works fine, mostly, but when I try to connect a DVD player in the auxiliary input, I get a nasty buzz - unless I disconnect the yellow RCA plug from the DVD player, but that's where the video is. And the audio is so low it sounds like it's being overheard from another source.
This DVD player was working fine on my old TV. I thought it might be the cheap adapter, but I bought another one on Amazon and same problem.
If it weren't 55", I might have taken it back to Walmart to have it looked at, but... Is the input busted? Should I just give up on DVD input?
Do you have a link to this adapter? What's the model number of the TV?

But I had the same problem with another.
Didn't it come with an adapter? It sounds like the colors may be mixed up (not all adapters are the same). With the TV set to the AV input, try each of the 3 connectors in the yellow DVD output and see if a picture ever appears.
Basically, it didn't. I did get a rough, quivering picture on one, but then no sound on the others. (The corresponding outlets worked fine on my old TV.)
I would contact TCL and see if they can send you an adapter. There's really no way to know if a random adapter is going to work.
I have tried two cables and get the same buzzing each time I plug the yellow RCA cable into the DVD player. I have also tried two different DVD players. I am getting the same results as the original complaint.
