How to turn off channel number displayed in TV screen

Hi Carl
Have you tried pressing the "Display" button on your remote, located centre right on the remote just above the number "3"
If you need an instruction manual you will find at the following link:

some tvs are set to hotel mode if they were bought for this and can have the channel number on all the time , you may be able to remove this using this manual. https://docs.sony.com/release/KV27S10.PDF it may help you to read this to remove it.

On your remote control (with tv off)
1. press Display, channel 5, Volume Up and then Power
this brings up the service mode (you will see some green text on your screen)
2. Press channel 2 to scroll through options until you see "Micro" in the upper left of your screen
(channel 2 cycles up through the options, channel 5 cycles down)
3. Press channel 1 to scroll through suboptions until you see "DIOF" appear under "Micro"
(channel 1 cycles up through the suboptions, channel 4 cycles down)
4. Press channel six until the default value (12:60) changes to 12:40
(channel 3 increases the value, channel 6 decreases the value)
5. Once the value has been changed to 12:40, press Muting and you should see red text in the upper right hand corner that says "Write"
6. Simply turn the power off and back on for the change to take effect. Your volume problems should now be fixed.

There should be a button marked i,press this and it should disappear

the tac switches have gone bad.this happens from age or sometimes from washing the screen of the set and moisture gets on the.. it is not a big job but it does involve soldering skills
