You can fix this issue of random pages turning black on a pdf by :
Toggle 'Display PDF in browser' on or off in Adobe Reader by going to Edit > Preferences > Internet. Then, to ensure that the configuration change takes place, close Adobe Reader.
Reopen the file if necessary. The PDF should open, depending on your new setting, either inside the browser or, if you selected Start PDF outside the browser, a new Adobe Reader window should open, this time outside the browser, with all of the material displayed. i hope this answer will help you to solve your query
