Hi, how can i get rid of an image on my PFD display has has an embedded colour image of CSB408 with in? The only way to get rid of it is to turn the brigtness down of EFIS.

Also, even with engine bleed valves, trim air, and packs the cabin altitude alert will not go off. I'm wobdering if a recent WEIN10 upgrade has damaged the 757. as it won't start properly either. I also notice taxiing is alot harder now too.
