1198 not powering down.

[JVB 73]

My 1198 wont power down with power button when I power it down it shuts down to a point that the screen is all pixilation and diferent colors hard to explain could it be a soft ware issue or maybe its because it is wired to fuse block instead of directly to battery current software 6.180 any ideas? The only way to shut down is to unplug unit my voltage is 12.6 thanks.
