TIA Portal V20 Unified Panel Images: Bug in start screen

He ririk,

Unfortunately, there will be some bugs found in the current V20 image in the future. And maybe you are right and have already found a bug. However, telling us more about your problem may help the community avoid the same problem. On my Unified Comfort Panel, I see no problem with the startup screen.

Kind regards
Stefan

Hi rerik,

Are you sure this is a firmware issue and not a hardware issue? Yes, your image shows a display error while the control panel is visible. Have you tried running a runtime project? Does this display error occur there as well? The same goes for installed applications like Firefox or File Manager. Is the error visible there?

It cannot be a general problem as none of the panels I have updated show an error like yours.

You can check the current boot loader version on your device and make a note of it's version. Then update the boot loader and try again. If the display error occurs during the boot loader update, your device probably has a hardware problem and needs to be repaired. However, even if updating the boot loader solves your problem, you should contact technical support to inform them of the problem.

Kind regards
Stefan

Hi Erik,

Hi Stefan.

Yes I am sure. I have the latest bootloader. With Image version V19.00.00.03 works fine.

When I updated to version V20 this happened. What you see in attached pic is a blank page. 

Now I downgraded back to version V19 and HMI works fine again. 

I will wait to a new image file until then I will not do an upgrade again.

Thanks anyway,

Erik

From your description, this appears to be a bug. However, this is not a common problem and is probably not yet known to the developers. So unless you report your problem to technical support, it may not be fixed in a future release.

So please create a support request. It may be helpful to the community to know the device type and article number of your panel.

Kind regards
Stefan
