How to add start up delay for the LCD;
It REALLY is as simple as what Mister_E said... where you have your "pause 100" command at the moment, change it to "pause 500". This SHOULD allow enought time for the LCD to settle. If this still does not help, change it to "Pause 2000" and try that. If that still does not work, your problem is unlikely to be LCD settle time. Post back if these do not work
