So managed to get to the menu with the info settings mute power buttons. I have attached a photo of the menu, it says failure, does that indicate what the fault is? The factory reset isn't in the main menu but within the first option section, as per photo. Should I proceed with the factory reset?
hopefully someone will have seen that failure screen before as i have not, i am still learning about firmware and software issues.
Sorry didn't mean to suggest you're not an expert, to me you are, just that I have no idea! It was a low end tv, but still £400 and expected to last longer than 2.5 years!

Yes, it can be located under the menu Only in no case should you change the parameters in this service menu, if you don’t know what for what, the changes can turn the TV into a brick (replacing the motherboard) if EMMc is alive, then the reset will go well if bad, then you can hang on the "SAMSUNG" screensaver, then how lucky you are.

So just did this, and it seemed to turn off and go into standby mode. Turned the tv on and it came up with the Samsung screen then went blank and back to the No signal screen but not coded correctly?

so, just tried a few things. I can't use the source button on the remote but can change with the buttons on the screen. But like before no sound and it says its optimising the video

not sure if you can re programe the eemc etc on these sets if a replacent mainboard is cheap maybe its worth going down that route will need a picture of your mainboard thats used in your tv plus on the metal tv chassis should be a white sticker with the lcd panel type.
no none seem too have a fix all the ones i have been reading says replace mainboard
Just tried a fix on the link you shared, one where you reset the apps. That too, no joy. Still getting the same thing. Interestingly I get the SID_No_Signal something and sometimes it displays properly, saying No Signal.
Ok so followed all of those steps but when I click on update now, it doesn't give me the option to use USB? Anyway just thinks a bit and then goes back to the No Signal screen. I check the version and it say 1310. Any idea how else I can update via the USB?
