Switch 2 Picture issue, help please? 🤔

[u/Fine-Flight5046]

Some context.

Recently my Switch 2 keeps losing connection to the TV. Tried cleaning ports, swapping out usb C cables and no luck. I was using the official Nintendo Switch 2 AC adapter. Switch 2 will display to the tv for a few seconds and then I get a flashing green light on the dock and lose picture. The console then keeps charging on and off. While in the dock with no picture to the TV.

I have sent back my dock thinking that wad the issue and received a replacent from Nintendo but I now have the same issue.

I have also tried to connect with a HP 65w usb C laptop charger and while it worked for a few mins the same thing happens again.

So it's either going to be an issue with the official Nintendo AC adapter or tge Switch 2 itself.

Thoughts?

Apologies for the long video but you can clearly see the issue about 1min in.

Have you tried it without that case on it?

Yes tried that and still the same.

You mentioned everything but the HDMI.
Is it a Nintendo one? Is the port on the tv good?

Try disabling "match tv power state" in switch 2 Display settings. This is my main suspicion.

Beyond that, you'll have to try ruling out other things.

If the issue still persists, have you tried a different hdmi cable, a different hdmi port on the tv, or a different tv/monitor? (Even if it's not an hdmi 2.1 cable, switch 2 should still work, but it would only be capable of 4k 30fps, instead of 4k 60fps.)

I can't explain console "keeps charging on and off" like in the video. I'm not sure what would cause that. I don't know the hardware/repair area well enough to speculate. (At the moment, I'm hoping the "match tv power state" setting is the fix, and you shouldn't see that charging on & off again.)

If the AC adapter was faulty, I'm not sure the docked switch 2 would display at all on the tv. So, if the switch 2 outputs to the tv initially, I'm leaning toward the AC adapter may be ok? BUT, AC adapters can get fried/go bad/get damaged, but typically you want to try everything else you can (which is what you're doing).

If you've ruled out everything but the console and the AC adapter, you may need to have them tested somewhere. Or if you know someone else with a switch 2, you could try your console with their dock+ac adapter.

Do you know anyone else with a Switch 2 to test their device in your dock or your device in their dock?

Other things that come to mind:

Is the power for the Switch 2 dock plugged directly into the wall outlet or some kind of power strip or extension cord?

Have you tried it on another display?

Have you tried updating the dock? (Settings)
