Hello

What type of cables /connection do you have between the cable box and tv ?

O.k then , would it be HDMI 1 for example ?

You are able to select the correct hdmi input and it says no signal ?

Expert:  Jack replied 1 month ago.

Can you try another hdmi input ?

It does happen that a single input will fail

Customer: replied 1 month ago.
It all seems to be fine. We get tv and can watch. It just says no input detected tv will turn off in one minute. No matter what we do it shuts down. We turn it back on and we're good for another 15.
Expert:  Jack replied 1 month ago.

O.k now this is odd , you mean that it works and then it sends that message ???

Could you please give me the model number written on the tv`s back cover ?

Customer: replied 1 month ago.

Expert:  Jack replied 1 month ago.

Do you have much programmed items done on this tv ?

We could try a factory reset but you will get back to first time setup.

Been looking for an option to turn off the no activity time out but no luck so far , some tv have it

Customer: replied 1 month ago.
Thanks. Worse comes to worse it's a new tv. Bummer, right????We're done here . Thank u for it help.
Expert:  Jack replied 1 month ago.

I am still looking if you want to wait a bit longer

Expert:  Jack replied 1 month ago.

Try this as a last ditch attempt but you will lose all your setup and have to restart them but at this point not much to lose

  1. On the supplied remote control, press the HOME button.
  2. Select Settings.
  3. Select Storage & reset.
  4. Select Factory data reset.

There is at least 2 more ways of resetting this tv beside the standard "arrow up on the remote and power on the tv itself"

You can see those at the link below;https://us.en.kb.sony.com/app/answers/detail/a_id/75705/p/61659,95543,95552,95718/c/65,66/kw/factory%20reset

Expert:  Jack replied 1 month ago.

This is an odd problem but i can tell you that it is definitely sitting on the tv`s main board , namely its eeprom and perhaps a firmware upgrade would do it if the reset does not work ; https://esupport.sony.com/US/p/model-home.pl?mdl=XBR75X850C&template_id=1&region_id=1&tab=download#/downloadTab
