My Samba 70-JRA22  has a scrambled screen. There are colored bands(vertical) on the screen. The program still runs but the display looks like the old tvs when the network would go off the air.  The touch aspect of the screen works as well.  Is there anything I can do?

This could be either hardware or software. On the off chance it's software, try the following:

- Make sure you have a copy of the VisiLogic project running on the PLC on your PC or laptop.

- Load a BLANK project into the PLC.

- Perform Initialize & Reset on the PLC.

- Re-load your original project.

If this doesn't fix the problem and you are able to see the boot text clearly, search this forum for additional help regarding firmware, etc.
