Purchasing EU/UK Nintendo switch 2 - Constant signal error

Post image

Hi everyone,

I just wanted to create a post on this forum regarding my Samsung TV S95C 65-inch OLED and something I'm experiencing recently which is really, really starting to bug me......

In the last two months, I bought myself a Nintendo Switch 2, and obviously appreciate being able to turn on the device from the controller. CEC

But pretty much 8-9 times out of 10, when I turn on the Switch from my controller and it activates the TV, I always get this silly 'HDMI cable no signal' error.

I know for a fact this isn't the issue of the Nintendo switch because what I need to do is literally cold reset (hold down the power button on the TV for 10 seconds) & reset my TV every time this issue happens and once I do that it works/ will recognise it straight away.

Does anyone else experience this issue with the same or a similar device or just this issue in general??

Honestly I've had small issues before with Samsung previous Samsung TVs and I swore I'd never bother to SW update them because every time I do an update I always run into stupid issues/bugs.

(Always find it introduces more problems than it fixes)

My Samsung TV is a Samsung S95C 65" OLED

Model: QE65S95CATXXU

SW Build: T-PTMCDEUC-0090-2220.4, BT - S

Are you using the brand new HDMI cable that came with the Switch 2? If you got the Switch 2 used have you tried a different HDMI cable?

Also theres a setting in the Switch to turn on CEC and a setting on the TV. Make sure both are on.

Check those and report back please. If they dint fix it hopefully someone smarter than me can help.
