Hi,

Have a look at the following link:

How do you do a SIMATIC HMI operating system update (firmware update, OS update) on operator panels or perform a "Reset to factory settings"?

It's possible using WinCC TIA Portal or Prosave.

Did you install the images for TIA Portal v19?

Best regards,

Hello,

It is possible to change brightness in Control panel/Settings of HMI panel.

Or you can use a System function in your project. (SetBrightness)

Best regards,

Hello milos23

do you have installed TIA Portal ?

for TP700 there is only a v17 Image the newest Image you can use, Siemens  has stopped developing Basic /Comfort/Advanced in v17. But of course you can program them in V19  (ut only with v17 Image).

In TIa you can also create a Image on USB Stick and then do the OS Updat directly on the Panel for example (if you have trouble with connecting)
