TV interference

[Chris38]

Does anyone know how to stop the continued reappearance of an icon on my Toshiba TV inviting me to instal a systems upgrade? Clicking OK merely produces a "searching" icon which fails to find the upgrade referred to. I thought it was illegal to interfere with the transmission of TV programmes.

Are you sure it is not that your TV has detected that the channels need updating and is suggesting that you do something about it?

I suspect that the system upgrade notification or similar has not been disabled.

The TV needs to be wifi enabled to update system or this can be done with a flash drive via the computer and plugged into the TV.

jomifl's channel update can be done without internet.

My belated thanks to jomifl and wildwood. Retuning seems to have worked. I still find it thoroughly objectionable that someone (presumably Toshiba themselves) is allowed to interfere with TV transmissions - I thought this was a criminal offence.

The transmission isn't being interfered with. Along with the sound and picture, engineering data is present on a transmission. You may have seen this on older analogue TVs as an occasional black band at the top of the screen with white dots running through it. The data includes program type, timing information, etc. If new software version information is received in this way, and it doesn't match that stored in your TV, the TV will show an upgrade recommendation. Usually, it's for your benefit as a viewer.
