Hardware Problem with joycons (but NOT the joycon drift!)

[APyroli]

Hello,

I have my switch since about a year and the joycons have never performed really well while on "TV" mode. It was fine for me as I was travelling a lot and has scant access to a TV set . But now I'm back home and have a TC but I can't really play if I'm more than 1 meter from the dock. Both joycons will loose signal with the switch, and I tried with different TV sets, and in different houses (away from routers and other possible sources of interference) . I even tried to take the joycons off the switch and play several meters (around 3 I think) from the small screen and it works fine. But as soon as the switch is docked, I have to be really close to it. Does anyone else have the same problem?
My switch is working with the last firmware version, the joycons are updated as well, and I tried several time the calibration thing.

I tried to ask the seller of the switch, and he wants me to send it back, but I will loose all my games data, as it's not transferable to the SD card.... Or is it?

Thanks to anyone that can help me with any of these questions!

After reading some topics on the same subject, it seems it might be some kind of "joycon drift" related problem, but I don't have any "ghost motions"... it is really strange

More seriously, signal looses are not the same problem as "joycon stick drift". However, it seemed to be a common issue:

Thanks so much for your reply! So now I know it just comes from the controllers and can just send them back to Nintendo before my warranty is over (in 2 weeks!) I'll just have to buy a pro controller in the meantime -_-'
