One connect box not working

[Glenn119]

I have a recently purchased (Oct 2022) 2022 Frame TV model QN55LS03BAFXZA and the tv just went off 1 night while I was watching tv. I cannot get the tv to come back on and it doesn’t seem to be getting power from the one connect box as I cannot see a power light on either box or tv. I checked the outlet and it is powered so I think the issue is with the one connect box. Is there a way to tell if the issue is with the one connect box? Can I just replace the one connect box? I have seen some posts that say the one connect box is matched to the individual TV. Is this easy to replace? Any help troubleshooting would be greatly appreciated.

@Glenn119: I'm sorry to hear that you have encountered this issue. In this instance, please take a look at the steps on page 219 of the user manual by following the link below (titled 'Unable to power on').

Although unlikely, you could also check that the issue is not with the power cable. If you have any other equipment that uses the same rated figure 8 cable (assuming you have the UK version), you could try swapping out the cable to rule out a cable or fuse issue.

I have an older Samsung curved tv and the one connect got damaged from a near by lightening strike and the service center (best buy) replaced it still work 8 yrs later. 

but my new QLED just did the same thing your tv did and I'm haveing a hard time trouble shooting and Samsung just wants me to buy a new tv and I'd rather not spend 5k if I can spend 500. did you find anything on your tv yet?

I have the exact same issue with 65" QN900B Neo QLED 8K, no power and can tell there is no power to the one connect as the optical port no longer shines red, has anyone had issues like this and had them resolved. Really not getting anywhere with customer service on what was a £3K plus tv at release and I have had it just under 2 years.
