prefs.php is not just an user config file as conf.php is. It defines the 
preferences, their type relationship a.s.o. So it's a system conf file as 
well. If you restore it from backup, you destroy this information which 
probably had been updated / changed.

Your original prefs.local.php had an error. Find it and keep your changes 
(only) there. If you get a blank screen, there probably is a PHP syntax 
error in one user file, which should be visible in the error log of your 
web server.

Also, your prefs.local.php file should look like:

$_prefs[<pref_name>]['value'|'hook'] = setting;

and should not mimmick prefs's syntax:

$__prefs[<name>] = array( ...
);
