Playback Issues - Audio/Video & Power

[Bubblehead97]

Please help I recently bought a tlc 65” Roku tv. Getting the switch to work hdmi 2 was ok at the beginning but got worse and worse cutting in and out. And now it won’t work at all saying no signal(is it on). I tried a different hdmi cord, unplugging the switch and tv, switching hdmi ports, checking for updates and none of it worked. I even factory reset the tv and after getting it all set up again I had audio and picture for about a second and a half before it cut out again. I have no idea what to do.

I am having a similar issue. We have a TCL Roku TV and have successfully connected and displayed our Nintendo Switch to the tv for over a year and a half. A few weeks ago it stopped working. I only get the Looking for a Signal message.

So far we have tried:

1. using a different HDMI cable
2. using different HDMI ports
3. unplugging all cables and reconnecting in the "proper" order
4. Restarting the TV along with #3
5. Restarting the TV and Switch along with #3

The one thing I haven't tried is resetting my Roku TV because that is a huge hassle and I get no indication for these support posts whether this actually solves this problem.

Please let me know of any other solutions to this issue, or whether Roku has documented it and is working on a fix.

Thanks.

Having the same issue and we bought a new switch terminal. I did try resetting my roku and it didn’t work. Please fix!! I want to play Just Dance with my friends on a big screen

Did you ever get the Switch to work?  Ours worked just fine when we first hooked it up, but now we get no signal and nothing we've tried (same steps listed above) has helped.  This is a huge disappointment.

@Burnsides7, yes, although the issue was with the Switch dock, not my TCL Roku TV. I experimented by connecting the dock to an external monitor, as well as borrowing a friend's newer Switch dock. The TV and external monitor both successfully connected with other HDMI inputs, as well as the borrowed dock. Turns out the Switch docks are very poorly made and this issue is widespread. I replaced the original dock with a refurbished one,  which works fine. Also, proceed with caution: there are plenty of 3rd party docks but apparently they can brick once there is a Switch update. Hope this helps. Good luck!

These steps actually worked for me:
